MXIC's Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29SL800C T/B is packaged in 48-pin TSOP and 48-ball CSP . It is designed to be reprogrammed and erased in system or in standard EPROM programmers. The standard MX29SL800C T/B offers access time as fast as 90ns, allowing operation of high-speed micropro- cessors without wait states. To eliminate bus conten- tion, the MX29SL800C T/B has separate chip enable (CE#) and output enable (OE#) controls. MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The MX29SL800C T/B uses a command register to manage this functionality. The command register allows for 100% TTL level control inputs and fixed power supply levels during erase and programming, while maintaining maxi- mum EPROM compatibility. MXIC Flash technology reliably stores memory contents even after 100,000 erase and program cycles. The MXIC cell is designed to optimize the erase and programming mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and program operations produces reliable cy- cling. The MX29SL800C T/B uses a 1.65V~2.2V VCC supply to perform the High Reliability Erase and auto Program/Erase algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up pro- tection is proved for stresses up to 100 milliamperes on address and data pin from -1V to VCC + 1V. REV. 1.0, APR. 20, 2006

P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 REQUIREMENTS FOR READING ARRAY DATA To read array data from the outputs, the system must drive the CE# and OE# pins to VIL. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid address on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered. WRITE COMMANDS/COMMAND SEQUENCES To program data to the device or erase sectors of memory , the system must drive WE# and CE# to VIL, and OE# to VIH. An erase operation can erase one sector, multiple sectors , or the entire device. Table indicates the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. The "Writing specific address and data commands or sequences into the command register initiates device operations. Table 1 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence resets the device to reading array data. Section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. After the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on Q7-Q0. Standard read cycle timings apply in this mode. Refer to the Autoselect Mode and Autoselect Command Sequence section for more information. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC Characteristics" section contains timing specification table and timing diagrams for write operations. STANDBY MODE When using both pins of CE# and RESET#, the device enter CMOS Standby with both pins held at Vcc ± 0.3V. If CE# and RESET# are held at VIH, but not within the range of VCC ± 0.3V, the device will still be in the standby mode, but the standby current will be larger. During Auto Algorithm operation, Vcc active current (Icc2) is required even CE# = "H" until the operation is completed. The device can be read with standard access time (tCE) from either of these standby modes, before it is ready to read data. OUTPUT DISABLE With the OE# input at a logic high level (VIH), output from the devices are disabled. This will cause the output pins to be in a high impedance state. RESET# OPERATION The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP , the device immediately terminates any operation in progress, tri- states all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS±0.3V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS±0.3V, the standby current will be greater. The RESET# pin may be tied to system reset circuitry. A system reset would that also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is completed within a
P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. Refer to the AC Characteristics tables for RESET# parameters and to Figure 22 for the timing diagram. READ/RESET COMMAND The read or reset operation is initiated by writing the read/ reset command sequence into the command register. Microprocessor read cycles retrieve array data. The de- vice remains enabled for reads until the command regis- ter contents are altered. If program-fail or erase-fail happen, the write of F0H will reset the device to abort the operation. A valid com- mand must then be written to place the device in the desired state. SILICON-ID READ COMMAND Flash memories are intended for use in applications where the local CPU alters memory contents. As such, manu- facturer and device codes must be accessible while the device resides in the target system. PROM program- mers typically access signature codes by raising A9 to a high voltage (VID). However, multiplexing high voltage onto address lines is not generally desired system de- sign practice. The MX29SL800C T/B contains a Silicon-ID-Read op- eration to supple traditional PROM programming meth- odology. The operation is initiated by writing the read silicon ID command sequence into the command regis- ter. Following the command write, a read cycle with A1=VIL, A0=VIL retrieves the manufacturer code of C2H/ 00C2H. A read cycle with A1=VIL, A0=VIH returns the device code of EAH/22EAH for MX29SL800CT, 6BH/ 226BH for MX29SL800CB. SET-UP AUTOMATIC CHIP/SECTOR ERASE COMMANDS Chip erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command 80H. Two more "unlock" write cycles are then followed by the chip erase command 10H or sector erase command 30H. The Automatic Chip Erase does not require the device to be entirely pre-programmed prior to executing the Auto- matic Chip Erase. Upon executing the Automatic Chip Erase, the device will automatically program and verify the entire memory for an all-zero data pattern. When the device is automatically verified to contain an all-zero pat- tern, a self-timed chip erase and verify begin. The erase and verify operations are completed when the data on Q7 is "1" at which time the device returns to the Read mode. The system is not required to provide any control or tim- ing during these operations. When using the Automatic Chip Erase algorithm, note that the erase automatically terminates when adequate erase margin has been achieved for the memory array (no erase verification command is required). If the Erase operation was unsuccessful, the data on Q5 is "1" (see Table 8), indicating the erase operation ex- ceed internal timing limit. The automatic erase begins on the rising edge of the last WE# or CE# pulse, whichever happens first in the com- mand sequence and terminates when the data on Q7 is "1" at which time the device returns to the Read mode, or the data on Q6 stops toggling for two consecutive read cycles at which time the device returns to the Read mode.

P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 SECTOR ERASE COMMANDS The Automatic Sector Erase does not require the de- vice to be entirely pre-programmed prior to executing the Automatic Sector Erase Set-up command and Au- tomatic Sector Erase command. Upon executing the Automatic Sector Erase command, the device will auto- matically program and verify the sector(s) memory for an all-zero data pattern. The system is not required to provide any control or timing during these operations. When the sector(s) is automatically verified to contain an all-zero pattern, a self-timed sector erase and verify begin. The erase and verify operations are complete when either the data on Q7 is "1" at which time the de- vice returns to the Read mode, or the data on Q6 stops toggling for two consecutive read cycles at which time the device returns to the Read mode. The system is not required to provide any control or timing during these operations. When using the Automatic sector Erase algorithm, note that the erase automatically terminates when adequate erase margin has been achieved for the memory array (no erase verification command is required). Sector erase is a six-bus cycle operation. There are two "un- lock" write cycles. These are followed by writing the set-up command 80H. Two more "unlock" write cycles are then followed by the sector erase command 30H. The sector address is latched on the falling edge of WE# or CE#, whichever happens later, while the command (data) is latched on the rising edge of WE# or CE#, whichever happens first. Sector addresses selected are loaded into internal register on the sixth falling edge of WE# or CE#, whichever happens later. Each succes- sive sector load cycle started by the falling edge of WE# or CE#, whichever happens later must begin within 50us from the rising edge of the preceding WE# or CE#, which- ever happens first. Otherwise, the loading period ends and internal auto sector erase cycle starts. (Monitor Q3 to determine if the sector erase timer window is still open, see section Q3, Sector Erase Timer.) Any command other than Sector Erase (30H) or Erase Suspend (B0H) during the time-out period resets the device to read mode. ERASE SUSPEND This command only has meaning while the state ma- chine is executing Automatic Sector Erase operation, and therefore will only be responded during Automatic Sector Erase operation. When the Erase Suspend Com- mand is issued during the sector erase operation, the device requires a maximum 20us to suspend the sector erase operation. However, when the Erase Suspend com- mand is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After this command has been executed, the command register will initiate erase suspend mode. The state machine will return to read mode automatically after suspend is ready. At this time, state machine only allows the command register to re- spond to Erase Resume, program data to , or read data from any sector not selected for erasure. The system can determine the status of the program operation using the Q7 or Q6 status bits, just as in the standard program operation. After an erase-suspend pro- gram operation is complete, the system can once again read array data within non-suspended sectors. ERASE RESUME This command will cause the command register to clear the suspend state and return back to Sector Erase mode but only if an Erase Suspend command was previously issued. Erase Resume will not have any effect in all other conditions. Another Erase Suspend command can be written after the chip has resumed erasing. However, a delay time must be required after the erase resume command (500us for MX29SL800C T/B), if the system implements an endless erase suspend/resume loop, or the number of erase suspend/resume is exceeded 1024 times. The erase times will be expended if the erase behavior always be suspended. (Please refer to MXIC Flash Application Note for details.) WORD/BYTE PROGRAM COMMAND SEQUENCE The device programs one word/byte of data for each program operation. The command sequence requires four bus cycles, and is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically generates the program pulses and verifies the programmed cell margin. Table 1 shows the address and data requirements for the byte program command sequence. When the Embedded Program algorithm is complete, the device then returns to reading array data and addresses are no longer latched. The system can
P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 WRITE OPERATION STATUS The device provides several bits to determine the sta- tus of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/ BY#. Table 10 and the following subsections describe the functions of these bits. Q7, RY/BY#, and Q6 each offer a method for determining whether a program or erase operation is complete or in progress. These three bits are discussed first. Q7: Data# Polling The DATA# polling bit, Q7, indicates to the host system whether an Automatic Algorithm is in progress or com- pleted, or whether the device is in Erase Suspend. DATA# polling is valid after the rising edge of the final WE# pulse in the program or erase command sequence. During the Automatic Program algorithm, the device out- puts on Q7 the complement of the datum programmed to Q7. This Q7 status also applies to programming dur- ing Erase Suspend. When the Automatic Program algo- rithm is complete, the device outputs the datum pro- grammed to Q7. The system must provide the program address to read valid status information on Q7. If a pro- gram address falls within a protected sector, DATA# poll- ing on Q7 is active for approximately 2 us, then the de- vice returns to reading array data. During the Automatic Erase algorithm, DATA# polling pro- duces a "0" on Q7. When the Automatic Erase algo- determine the status of the program operation by using Q7, Q6, or RY/BY#. See "Write Operation Status" for information on these status bits. Any commands written to the device during the Em- bedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the programming operation. The Byte Program command sequence should be reinitiated once the device has reset to reading array data, to ensure data integrity. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from a "0" back to a "1". Attempting to do so may halt the operation and set Q5 to "1" , or cause the DATA# polling algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still "0". Only erase operations can convert a "0" to a "1". rithm is complete, or if the device enters the Erase Sus- pend mode, DATA# polling produces a "1" on Q7. This is analogous to the complement/true datum out-put de- scribed for the Automatic Program algorithm: the erase function changes all the bits in a sector to "1" prior to this, the device outputs the "complement," or "0". The system must provide an address within any of the sec- tors selected for erasure to read valid status information on Q7. After an erase command sequence is written, if all sec- tors selected for erasing are protected, DATA# polling on Q7 is active for approximately 100 us, then the device returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. When the system detects Q7 has changed from the complement to true data, it can read valid data at Q7-Q0 on the following read cycles. This is because Q7 may change asynchronously with Q0-Q6 while Output En- able (OE#) is asserted low. RY/BY# : Ready/Busy The RY/BY# is a dedicated, open-drain output pin that indicates whether an Automatic Erase/Program algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# or CE#, whichever happens first, in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the de- vice is ready to read array data (including during the Erase Suspend mode), or is in the standby mode. Table 8 shows the outputs for RY/BY# during write op- eration. Q6:Toggle BIT I Toggle Bit I on Q6 indicates whether an Automatic Pro- gram or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# or CE#, whichever
P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 During an Automatic Program or Erase algorithm opera- tion, successive read cycles to any address cause Q6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, Q6 stops toggling. After an erase command sequence is written, if all sec- tors selected for erasing are protected, Q6 toggles and returns to reading array data. If not all selected sectors are protected, the Automatic Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use Q6 and Q2 together to determine whether a sector is actively erasing or is erase sus- pended. When the device is actively erasing (that is, the Automatic Erase algorithm is in progress), Q6 toggling. When the device enters the Erase Suspend mode, Q6 stops toggling. However, the system must also use Q2 to determine which sectors are erasing or erase-sus- pended. Alternatively, the system can use Q7. If a program address falls within a protected sector, Q6 toggles for approximately 2 us after the program com- mand sequence is written, then returns to reading array data. Q6 also toggles during the erase-suspend-program mode, and stops toggling once the Automatic Program algo- rithm is complete. Table 8 shows the outputs for Toggle Bit I on Q6. Q2:Toggle Bit II The "Toggle Bit II" on Q2, when used with Q6, indicates whether a particular sector is actively erasing (that is, the Automatic Erase algorithm is in process), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# or CE#, whichever happens first, in the command sequence. Q2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But Q2 cannot distinguish whether the sector is actively erasing or is erase-suspended. Q6, by com- parison, indicates whether the device is actively eras- ing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sectors and mode information. Refer to Table 8 to compare outputs for Q2 and Q6. Reading Toggle Bits Q6/ Q2 Whenever the system initially begins reading toggle bit status, it must read Q7-Q0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on Q7-Q0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the sys- tem also should note whether the value of Q5 is high (see the section on Q5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as Q5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase op- eration. If it is still toggling, the device did not complete the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that system initially determines that the toggle bit is toggling and Q5 has not gone high. The system may continue to monitor the toggle bit and Q5 through successive read cycles, determining the sta- tus as described in the previous paragraph. Alterna- tively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation. Exceeded Timing Limits Q5 will indicate if the program or erase time has ex- ceeded the specified limits (internal pulse count). Under these conditions Q5 will produce a "1". This time-out condition indicates that the program or erase cycle was not successfully completed. Data# Polling and Toggle Bit are the only operating functions of the device under this condition. happens first, in the command sequence (prior to the program or erase operation), and during the sector time- out.

P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 POW ER SUPPLY DECOUPLING In order to reduce power switching effect, each device should have a 0.1uF ceramic capacitor connected be- tween its VCC and GND. POWER-UP SEQUENCE The MX29SL800C T/B powers up in the Read only mode. In addition, the memory contents may only be altered after successful completion of the predefined command sequences. TEMPORARY SECTOR UNPROTECTED This feature allows temporary unprotected of previously protected sector to change data in-system. The Tempo- rary Sector Unprotected mode is activated by setting the RESET# pin to VID (10V-11V). During this mode, formerly protected sectors can be programmed or erased as un-protected sector. Once VID is remove from the RESET# pin, all the previously protected sectors are protected again. SECTOR PROTECTION The MX29SL800C T/B features hardware sector protec- tion. This feature will disable both program and erase operations for these sectors protected. To activate this mode, the programming equipment must force VID on address pin A9 and OE#. Programming of the protection circuitry begins on the falling edge of the WE# pulse and is terminated on the rising edge. Please refer to sector protect algorithm and waveform. To verify programming of the protection circuitry, the pro- gramming equipment must force VID on address pin A9 ( with CE# and OE# at VIL and WE# at VIH). When A1=VIH, A0=VIL, A6=VIL, it will produce a logical "1" code at device output Q0 for a protected sector. Other- wise the device will produce 00H for the unprotected sector. In this mode, the addresses, except for A1, are don't care. Address locations with A1 = VIL are reserved to read manufacturer and device codes. (Read Silicon ID) It is also possible to determine if the sector is protected in the system by writing a Read Silicon ID command. Performing a read operation with A1=VIH, it will produce Sector Erase Timer After the completion of the initial sector erase command sequence, the sector erase time-out will begin. Q3 will remain low until the time-out is complete. DATA# polling and Toggle Bit are valid after the initial sector erase com- mand sequence. If DATA# polling or the Toggle Bit indicates the device has been written with a valid erase command, Q3 may be used to determine if the sector erase timer window is still open. If Q3 is high ("1") the internally controlled erase cycle has begun; attempts to write subsequent commands to the device will be ignored until the erase operation is completed as indicated by DATA# polling or Toggle Bit. If Q3 is low ("0"), the device will accept additional sector erase commands. To insure the com- mand has been accepted, the system software should check the status of Q3 prior to and following each sub- sequent sector erase command. If Q3 were high on the second status check, the command may not have been accepted. DATA PROTECTION The MX29SL800C T/B is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transition. During power up the device automatically re- sets the state machine in the Read mode. In addition, with its control register architecture, alteration of the memory contents only occurs after successful comple- tion of specific command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up and power-down tran- sition or system noise. WRITE PULSE "GLITCH" PROTECTION Noise pulses of less than 5ns(typical) on CE# or WE# will not initiate a write cycle. LOGICAL INHIBIT Writing is inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle CE# and WE# must be a logical zero while OE# is a logical one.
P/N:PM1224 MX29SL800C T/B REV. 1.0, APR. 20, 2006 a logical "1" at Q0 for the protected sector. CHIP UNPROTECTED The MX29SL800C T/B also features the chip unprotected mode, so that all sectors are unprotected after chip un- protected is completed to incorporate any changes in the code. It is recommended to protect all sectors before activating chip unprotected mode. To activate this mode, the programming equipment must force VID on control pin OE# and address pin A9. The CE# pins must be set at VIL. Pins A6 must be set to VIH. Refer to chip unprotected algorithm and waveform for the chip unprotected algorithm. The unprotection mechanism begins on the falling edge of the WE# pulse and is terminated on the rising edge. It is also possible to determine if the chip is unprotected in the system by writing the Read Silicon ID command. Performing a read operation with A1=VIH, it will produce 00H at data outputs (Q0-Q7) for an unprotected sector. It is noted that all sectors are unprotected after the chip unprotected algorithm is completed.
