Overview

The AT24C08C is an 8-Kbit serial EEPROM that provides non-volatile data storage through an I2C-compatible interface. It supports a wide operating voltage range from 1.7V to 5.5V, making it suitable for various embedded systems. Its high reliability features like 1,000,000 write cycles and 100-year data retention ensure long-term data integrity.

Why Choose This Part

This EEPROM offers a simple I2C interface, making integration with microcontrollers straightforward. Its low standby current of 6 uA is beneficial for battery-powered applications, and the wide supply voltage range from 1.7V to 5.5V increases design flexibility. The write-protect pin provides hardware data protection, enhancing system security.

Applications

Data Logging
Store configuration settings, calibration data, or event logs in embedded systems like industrial control units or IoT devices.
Parameter Storage
Save user preferences, operating modes, or system parameters that need to persist across power cycles in consumer electronics.
Sensor Calibration
Store calibration coefficients for sensors to maintain accuracy without needing re-calibration after power loss.
System Configuration
Retain critical system settings for microcontrollers, ensuring proper operation from power-up.
Embedded System Memory
Provide additional non-volatile storage for microcontrollers that have limited internal EEPROM or flash.
