Descriptions:

  • The 93C66PC is a non-volatile memory device that allows data to be electrically erased and reprogrammed.
  • It supports both 8-bit and 16-bit organization modes.
  • Features a sequential read operation for faster data access.
  • Includes built-in write protection via software control.

Features:

  • Low Power Consumption:
  • Active current: 1mA (typical)
  • Standby current: 10µA (typical)
  • Self-Timed Programming Cycle
  • Software-Controlled Write Protection
  • Industrial Temperature Range Support
  • High Reliability:
  • ESD protection
  • Noise immunity

This EEPROM is commonly used in applications requiring small, reliable non-volatile memory storage, such as automotive, industrial, and consumer electronics.

(Note: Atmel was acquired by Microchip Technology in 2016, but legacy part numbers like 93C66PC remain in use.)
