93C66A - Microchip Technology

93C66A 4K Microwire Compatible Serial EEPROM

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. For dedicated 8-bit communication, the 93XX66A devices are available, while the 93XX66B devices prov.
