93LC56B - 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. For dedicated 8-bit communication, the 9.
