Overview

The AT24C08D-SSHM-T is an 8-Kbit I2C serial EEPROM organized as 1024 words of 8 bits each. It operates across a wide voltage range of 1.7V to 3.6V and supports a 1 MHz clock frequency for high-speed data transfers in space-constrained embedded systems.

Why Choose This Part

This device features a low standby current of 0.8 uA and a hardware write-protect pin for robust data security. It offers high reliability with 1,000,000 write cycles, 100-year data retention, and integrated Schmitt triggers on inputs for noise suppression.

Applications

Configuration Storage
Storing calibration data, user settings, and network configuration parameters in consumer electronics.
Asset Tracking
Maintaining small logs of identification data and operational history in portable tracking devices.
Board Identification
Used on mezzanine cards or peripheral modules to store revision info and serial numbers for host detection.

Getting Started

Connect the SCL and SDA lines to an I2C host with appropriate pull-up resistors, and tie the WP pin to GND for write access or VCC for protection. For development, use standard I2C libraries such as the Microchip XC8 peripheral libraries or the Arduino Wire library, targeting address 0x50.
