The Microchip Technology Inc. 93XX66A/B/C devices are 4Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA66C, 93LC66C or 93C66C are dependent upon external logic levels driving the ORG pin to set word size. Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications. They are available in various packages including PDIP, SOIC, MSOP, SOT-23, DFN/TDFN and TSSOP.
