93LC46A Datasheet (Microchip Technology) - 1-Kbit Microwire Compatible Serial EEPROM

93LC46A, 1-Kbit Microwire Compatible Serial EEPROM

The Microchip Technology Inc.

93XX46A/B/C devices are 1-Kbit low-voltage serial Electrically Erasable PROMs (EEPROM).

Word-selectable devices such as the 93AA46C, 93LC46C or 93C46C are dependent upon external logic levels driving the ORG pin to set word size.

For dedicated 8-bit communication, the 9
