E-CMOS Corp. ( www.ecmos.com.tw ) Page 1 of 14 2G30N-Rev.F001 General Description Features The EC93C56A/66A provides 2048/4096 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 128/256 words of 16 bits each, when the ORG pin is connected to VCC and 256/512 words of 8 bits each when it is tied to ground. The EC93C56A/66A is available in space-saving PDIP-8, SOP-8, TSSOP-8, MSOP-8, and DFN- 8 packages. The EC93C56A/66A is enabled through the Chip Select pin (CS), and accessed via a 3-wire serial interface consisting of Data I nput (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The WRITE cycle is completely self-timed and no separate erase cycle is requi red before write. The Write cycle is only enabled when it is in the Erase/Write Enable state. When CS is brought “high” following the initiation of a write cycle, the DO pin outputs the Ready/Busy status. /circle6 Low-voltage Operation - 1.7V (VCC = 1.7V to 5.5V) /circle6 Three-wire Serial Interface /circle6 Sequential Read Operation /circle6 2 MHz Clock Rate (5V) Compatibility /circle6 Self-timed Write Cycle (5 ms max) /circle6 High-reliability - Endurance: 1 Million Write Cycles - Data Retention: 100 Years /circle6 PDIP-8, SOP-8, TSSOP-8, MSOP-8 and DFN-8 packages.

E-CMOS Corp. ( www.ecmos.com.tw ) Page 2 of 14 2G30N-Rev.F001 Block Diagram Notes: When the ORG pin is connected to VCC, the “x 16” organization is selected. When it is connected to ground, the “x 8” organization is selected. If the ORG pin is left unconnected and the application does not load the input beyond the capability of the internal 1 Meg ohm pullup, then the “x 16” organization is selected.
E-CMOS Corp. ( www.ecmos.com.tw ) Page 3 of 14 2G30N-Rev.F001 Function Descriptions The EC93C56A/66A is accessed via a simple and versatile three-wire serial communication interfac e. Device operation is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising edge of CS and consists of a start bit (logic“1”) followed by the appropriate op code and the desired memory address location. Instruction set for the EC 93C56 A /66 A Instruction SB OP Code Address Data Comments x8 x16 x8 x16 READ 1 10 A 8 - A0 A 7 - A0 Reads data stored in memory, at specified address EWEN 1 00 11XXXXXXX 11XXXXXX Write enable must precede all programming modes ERASE 1 11 A 8 - A0 A 7 - A0 Erase memory location An - A0 WRITE 1 01 A 8 - A0 A 7 - A0 D 7 - D0 D 15 - D0 Writes memory location An - A0 ERAL 1 00 10XXXXXXX 10XXXXXX Erases all memory locations.

Valid only at VCC=4.5V to 5.5V EWDS 1 00 00XXXXXXX 00XXXXXX Disables all programming instructions Notes: The X's in the address field represent don't care values and must be clocked. READ (READ ): The Read (READ) instruction contains the address code for the memory location to be read. After the instruction and address are decoded, data from the selected memory location is available at the serial output pin DO. Output data changes are synchronize d with the rising edges of serial clock SK. It should be noted that a dummy bit (logic “0”) precedes the 8- or 16-bit data output string. The EC93C56A/66A supports sequential read operations. The device will automatically increment the internal address poi nter and clock out the next memory location as long as Chip Select (CS) is held high .In this case, the dummy bit (logic “0”) will not be clocked out between memory locations, thus allowing for a continuous steam of data to be read. ERASE/WRITE (EWEN): To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when power is first applied. An Erase/Write Enable (EWEN) instruction must be executed first before any programming instructions can be carried out. Please note that once in the EWEN state, programming remains enabled until an EWDS instruction is executed or VCC power is removed from the part. ERASE (ERASE): The Erase (ERASE) instruction programs all bits in the specified memory location to the logical “1” state. The self-timed erase cycle starts once the ERASE instruction and address are decoded. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (TCS). A logic “1” at pin DO indicates that the selected memory location has been erased, and the part is ready for another instruction. WRITE (WRITE): The Write (WRITE) instruction contains the 8 or 16 bits of data to be written into the specified memory location. The self-timed programming cycle, tW P, starts after the last bit of data is received at serial data input pin DI. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (TCS). A logic “0” at DO indicates that programming is sti ll in progress. A logic “1” indicates that the memory location at the specified address has been written with the data pattern contained in the instruction and the part is ready for further instructions. A Ready/Busy status cannot be obtained if the CS is brought high after the end of the selftimed programming cycle, TWP. ERASE ALL (ERAL): The Erase All (ERAL) instruction programs every bit in the memory array to the logic “1” state and is primarily used for testing purposes. The DO pin outputs the Ready/ Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (TCS). The ERAL instruction is valid only at VCC = 5.0V ± 10%.
E-CMOS Corp. ( www.ecmos.com.tw ) Page 4 of 14 2G30N-Rev.F001 Function Descriptions WRITE ALL (WRAL): The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the instruction. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (TCS). The WRAL instruction is valid only at VCC = 5.0V ± 10%. ERASE/WRI TE DISABLE (EWDS): To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all programming modes and should be executed after all programming operations. The operation of the Read instruction is independent of both t he EWEN and EWDS instructions and can be executed at any time.
