N93C66 Datasheet, ON Semiconductor

sequential read and self−timed internal write with auto−clear. On−chip Power−On Reset circuitry protects the internal logic against powering up in the wrong state. Featur.

The N93C66 is a 4 kb CMOS Serial EEPROM device which is organized as either 256 registers of 16 bits (ORG pin at VCC) or 512 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The device.
