93C66C-E/ST Description:

The Microchip Technology Inc. 93XX66A/B/C devicesare 4Kbit low-voltage serial Electrically ErasablePROMs (EEPROM). Word-selectable devices such asthe 93AA66C, 93LC66C or 93C66C are dependentupon external logic levels driving the ORG pin to setword size. For dedicated 8-bit communication, the93XX66A devices are available, while the 93XX66Bdevices provide dedicated 16-bit communication.Advanced CMOS technology makes these devicesideal for low-power, nonvolatile memory applications.The entire 93XX Series is available in standardpackages including 8-lead PDIP and SOIC, andadvanced packaging including 8-lead MSOP, 6-leadSOT-23, 8-lead 2x3 DFN/TDFN and 8-lead TSSOP. Allpackages are Pb-free (Matte Tin) finish. 2003-2011 Microchip Technology Inc.DS21795E-page 1
