93C66B - 4K Microwire Compatible Serial EEPROM

Download the 93C66B datasheet PDF. This datasheet also covers the 93C66C variant, as both devices belong to the same 4k microwire compatible serial eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

The Microchip Technology Inc.

93XX66A/B/C devices are 4-Kbit 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.

Key Features

  • Low-Power CMOS Technology.
  • ORG Pin to Select Word Size for ‘66C’ Version.
  • 512 x 8-bit Organization ‘A’ Devices (no ORG).
  • 256 x 16-bit organization ‘B’ Devices (no ORG).
  • Self-tImed Erase/Write Cycles (including Auto-Erase).
  • Automatic Erase All (ERAL) Before Write All (WRAL).
  • Power-On/Off Data Protection Circuitry.
  • Industry Standard Three-Wire Serial I/O.
  • Device Status Signal (Ready/Busy).
  • Sequential Read Fu.
