Description

The AT93C56A/66A provides 2048/4096 bits of serial electrically erasable program-

mable 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 device is optimized for use in many industrial and commercial

applications where low power and low voltage operations are essential. The

AT93C56A/66A is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead

EIAJ SOIC, 8-lead MAP, 8-lead TSSOP and 8-ball dBGA2™ packages.

The AT93C56A/66A is enabled through the Chip Select pin (CS), and accessed via a

3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock

(SK). Upon receiving a READ instruction at DI, the address is decoded and the data is
