The Microchip Technology Inc. 93LC66CT-I/SN devices are 4Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices 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. The entire 93XX Series is available in standard packages including PDIP and SOIC, and advanced packaging including MSOP, SOT-23, DFN/TDFN and TSSOP.
