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.
