AT93C66A-10SQ-2.7

EEPROM Serial-3Wire 4Kbit 512 x 8/256 x 16 3.3V/5V Automotive 8Pin SOIC

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.
