93LC56A Datasheet (Microchip Technology) - 2-Kbit Microwire Compatible Serial EEPROM

93LC56A, 2-Kbit Microwire Compatible Serial EEPROM

The Microchip Technology Inc.

93XX56A/B/C devices are 2-Kbit low-voltage serial Electrically Erasable PROMs (EEPROM).

Word-selectable devices such as the 93AA56C, 93LC56C or 93C56C are dependent upon external logic levels driving the ORG pin to set word size.
