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.
