Description

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 industrial and com-

mercial applications 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 and EIAJ
