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. These devices are ideal for low-power, nonvolatile memory applications and are available in various packages including PDIP, SOIC, MSOP, SOT-23, DFN/TDFN, and TSSOP.
