Description
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 munication, the 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit munication. Advanced CMOS technology makes these devices ideal for lowpower, nonvolatile memory applications.
