The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT59C11/22/13 is available in space saving 8-pin PDIP and 8-pin EIAJ SOIC packages. The AT59C11/22/13 is enabled through the Chip Select pin (CS), and accessed via a 4-wire serial interface consisting of Data Input (DI), Data Output (DO), and Clock (CLK). 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 selftimed and no separate ERASE cycle is required before WRITE. The WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. Ready/Busy status can be monitored upon completion of a programming operation by polling the Ready/Busy pin. The AT59C11/22/13 is available in 5.0V ± 10%, 2.7V to 5.5V and 2.5V to 5.5V versions. 4K (512 x 8 or 256 x 16) Pin Configurations Pin Name Function CS Chip Select CLK Serial Data Clock DI Serial Data Input DO Serial Data Output GND Ground VCC Power Supply ORG Internal Organization RDY/BUSY Status Output 8-Pin PDIP AT59C11 AT59C22 AT59C13 4-Wire, 1K Serial E2PROM 8-Pin SOIC Rev. 0173K–07/98 1 Absolute Maximum Ratings* Operating Temperature .................................. -55°C to +125°C Storage Temperature ..................................... -65°C to +150°C Voltage on Any Pin with Respect to Ground .....................................-1.0V to +7.0V Maximum Operating Voltage........................................... 6.25V *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

AT59C11/22/13 Functional Description The AT59C11/22/13 are accessed via a simple and versatile 4-wire serial communication interface. Device operation is controlled by six 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. 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 synchronized with the rising edges of serial clock CLK. It should be noted that a dummy bit (logic ‘0’) precedes the 8- or 16-bit data output string. 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 Erase/Write Enable state, programming remains enabled until an Erase/Write Disable (EWDS) instruction is executed or VCC power is removed from the part. 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, tWP, starts after the last bit of data is received at serial data input pin DI. The Ready/Busy status of the AT59C11/22/13 can be determined by polling the RDY/BUSY pin. A logic ‘0’ at RDY/BUSY indicates that programming is still 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. 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 Ready/Busy status of the AT59C11/22/13 can be determined by polling the RDY/BUSY pin. The ERAL instruction is valid only at VCC = 5.0V ± 10%. WRITE ALL (WRAL): The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the instruction. The Ready/Busy status of the AT59C11/22 /1 3 can be de termi ned by pol ling the RDY/BUSY pin. The WRAL instruction is valid only at VCC = 5.0V ± 10%. ERASE/WRITE 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 the EWEN and EWDS instructions and can be executed at any time. Timing Diagrams Synchronous Data Timing Note: 1.
