描述 Description

The AT93C56A/66A provides 2048/4096 bits of serial electrically-erasable programmable read-only memory (EEPROM). The EEPROM is organized as 128/256 words of 16 bits each when the ORG pin is connected to VCC and 256/512 words of 8 bits each when it is tied to ground. The device is optimized for use in many automotive applications where low-power and low-voltage operations are essential. The AT93C56A/66A is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages.
