AT93C57 Datasheet 3-wire Serial Eeproms

Manufacturer: Atmel (now Microchip Technology)

General Description

The AT93C46/56/57/66 provides 1024/2048/4096 bits of serial electrically erasable programmable 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 industrial and commerc
