Descriptions:

  • The 93LC56 is a low-power, serial EEPROM designed for small, non-volatile storage applications.
  • It supports both 8-bit and 16-bit organization modes.
  • Features a simple 3-wire serial interface (CS, SK, DI/DO) for easy microcontroller interfacing.
  • Includes built-in write protection via software control.

Features:

  • Low Power Consumption:
  • Active Read Current: 1mA (typical)
  • Standby Current: 1µA (typical)
  • Sequential Read Operation: Allows faster data access.
  • Self-Timed Write Cycle: No external timing components required.
  • Built-in Error Checking: Ensures data integrity.
  • Industrial-Grade Reliability: High endurance and long data retention.

This EEPROM is commonly used in embedded systems, automotive electronics, and consumer devices for parameter storage and configuration settings.
