93LC66B Datasheet 4K Microwire Compatible Serial EEPROM

Manufacturer: Microchip Technology

General Description

The Microchip Technology Inc.

93XX66A/B/C devices are 4-Kbit low-voltage serial Electrically Erasable PROMs (EEPROM).

Word-selectable devices such as the 93AA66C, 93LC66C or 93C66C are dependent upon external logic levels driving the ORG pin to set word size.
