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 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.
