2 Am29SL400D Rev. A Amend. +1 April 13, 2005 ADVANCE INFORMATION GENERAL DESCRIPTION The Am29SL400D is an 4Mbit, 1.8 V volt-only Flash memory organized as 524,288 bytes or 262,144 words. The device is offered in a 48-ball FBGA package. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed and erased in-system with a single 1.8 volt V CC supply. No VPP is required for write or erase operations. The device can also be pro- grammed in standard EPROM programmers. The standard device offers access times of 90, 100, and 120 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The device requires only a single 1.8 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard . Com- mands are written to the command register using stan- dard microprocessor write timings. Register contents serve as input to an internal state-machine that con- trols the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm—an internal algorithm that auto- matically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facili- tates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm—an internal algorithm that automati- cally preprograms the array (if it is not already pro- grammed) before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low V CC detector that automatically inhibits write opera- tions during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via pro- gramming equipment. The Erase Suspend feature enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. The hardware RESET# pin terminates any operation in progress and resets the internal state machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode . The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. AMD’s Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection.

April 13, 2005 Rev. A Amend. +1 Am29SL400D 9 ADVANCE INFORMATION See “ Reading Array Data, on page 13 for more infor- mation. Refer to the AC Read Operations table for timing specifications and to Figure 13, on page 26 for the timing diagram. I CC1 in the DC Characteristics table represents the active current specification for reading array data. Writing Commands/Command Sequences To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to V IL, and OE# to VIH. For program operations, the BYTE# pin determines whether the device accepts program data in bytes or words. Refer to Word/Byte Configuration, on page 8 for more information. The device features an Unlock Bypass mode to facili- tate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. The Word/Byte Program Command Sequence, on page 14 has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sec- tors, or the entire device. Tables 2 and 3 indicate the address space that each sector occupies. A “sector address” consists of the address bits required to uniquely select a sector. The Command Definitions, on page 17 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 DQ7–DQ0. Standard read cycle timings apply in this mode. Refer to the Autoselect Mode and Autose- lect Command Sequence sections for more informa- tion. I CC2 in the DC Characteristics table represents the active current specification for the write mode. The AC Characteristics, on page 26 contains timing specifica- tion tables and timing diagrams for write operations. Program and Erase Operation Status During an erase or program operation, the system may check the status of the operation by reading the status bits on DQ7–DQ0. Standard read cycle timings and I CC read specifications apply. Refer to Write Operation Status, on page 18 for more information, and to AC Characteristics, on page 26 for timing diagrams. Standby Mode When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, inde- pendent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# pins are both held at V CC ± 0.2 V. (Note that this is a more restricted voltage range than V IH.) If CE# and RESET# are held at VIH, but not within VCC ± 0.2 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (t CE) for read access when the device is in either of these standby modes, before it is ready to read data. The device also enters the standby mode when the RESET# pin is driven low. Refer to the next section, RESET#: Hardware Reset Pin. If the device is deselected during erasure or program- ming, the device draws active current until the operation is completed. I CC3 in the DC Characteristics table represents the standby current specification. Automatic Sleep Mode The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for t ACC + 50 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system. I CC4 in the DC Characteristics table represents the automatic sleep mode current specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of reset- ting the device to reading array data. When the RESET# pin is driven low for at least a period of t RP, the device immediately terminates any operation in progress, tristates 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 V SS±0.2 V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS±0.2 V, the standby current will be greater.

14 Am29SL400D Rev. A Amend. +1 April 13, 2005 ADVANCE INFORMATION before erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is com- plete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to reading array data (also applies to programming in Erase Suspend mode). Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to reading array data (also applies to autoselect during Erase Suspend). If DQ5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Sus- pend). Autoselect Command Sequence The autoselect command sequence allows the host system to access the manufacturer and devices codes, and determine whether or not a sector is protected. Table 5 on page 17 shows the address and data requirements. This method is an alternative to that shown in Table 4 on page 11 , which is intended for PROM programmers and requires V ID on address bit A9. The autoselect command sequence is initiated by writing two unlock cycles, followed by the autoselect command. The device then enters the autoselect mode, and the system may read at any address any number of times, without initiating another command sequence. A read cycle at address XX00h retrieves the manufacturer code. A read cycle at address 01h in word mode (or 02h in byte mode) returns the device code. A read cycle containing a sector address (SA) and the address 02h in word mode (or 04h in byte mode) returns 01h if that sector is protected, or 00h if it is unprotected. Refer to Table 2 on page 10 and Table 3 on page 10 for valid sector addresses. The system must write the reset command to exit the autoselect mode and return to reading array data. Word/Byte Program Command Sequence The system may program the device by word or byte, depending on the state of the BYTE# pin. Program- ming is a four-bus-cycle operation. The program command sequence 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 tim- ings. The device automatically generates the program pulses and verifies the programmed cell margin. Table 5 on page 17 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 determine the status of the program operation by using DQ7, DQ6, or RY/BY#. See Write Operation Status, on page 18 for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the program- ming 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 DQ5 to “1”, or cause the Data# Polling algorithm to indicate the operation was suc- cessful. However, a succeeding read will show that the data is still “0”. Only erase operations can convert a “0” to a “1”. Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes or words to the device faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is pro- grammed in the same manner. This mode dispenses with the initial two unlock cycles required in the stan- dard program command sequence, resulting in faster total programming time. Write Operation Status, on page 18 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data 90h; the second cycle the data 00h. Addresses are don’t cares. The device then returns to reading array data. Figure 3, on page 15 illustrates the algorithm for the program operation. See the Erase/Program

April 13, 2005 Rev. A Amend. +1 Am29SL400D 37 ADVANCE INFORMATION ERASE AND PROGRAMMING PERFORMANCE Notes: 1. Typical program and erase times assume the following conditions: 25 °C, 1.8 V VCC, 1,000,000 cycles. Additionally, programming typicals assume checkerboard pattern. 2. Under worst case conditions of 90°C, V CC = 1.8 V, 1,000,000 cycles. 3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes program faster than the maximum program times listed. 4. In the pre-programming step of the Embedded Erase algor ithm, all bytes are programmed to 00h before erasure. 5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table 5 on page 17 for further information on command definitions. 6. The device has a minimum guaranteed erase and program cycle endurance of 1,000,000 cycles. LATCHUP CHARACTERISTICS Includes all pins except VCC. Test conditions: VCC = 1.8 V , one pin at a time. TSOP PIN AND BGA PACKAGE CAPACITANCE Notes: 1. Sampled, not 100% tested. 2. T est conditions TA = 25°C, f = 1.0 MHz.
