2K (256 x 8 or 128 x 16)

4K (512 x 8 or 256 x 16)

The AT93C46/56/66 provides 1024/2048/4096 bits of serial electrically erasable pro-

grammable read only memory (EEPROM) organized as 64/128/256 words of 16 bits

each, when the ORG pin is connected to VCC and 128/256/512 words of 8 bits each

when it is tied to ground. The device is optimized for use in many automotive applica-

tions where low power and low voltage operations are essential. The AT93C46/56/66

is available in space-saving 8-lead PDIP and 8-lead JEDEC SOIC packages.
