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 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devic...
