The Microchip Technology Inc. 93XX86A/B/C devices are 16K bit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93XX86C are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93XX86A devices are available, while the 93XX86B devices provide dedicated 16-bit communication, available on SOT-23 devices only.
