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 V_CCand 128/256/512 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 AT93C46/56/57/66 is available in space saving 8-pin PDIP and 8-pin JEDEC and

EIAJ SOIC packages.
