Overview

The AT24CS01-SSHM-T is a 1Kbit I2C Serial EEPROM featuring a factory-programmed, read-only 128-bit unique serial number. It operates over a wide voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz, providing reliable non-volatile storage for small-scale configuration data and device identification.

Why Choose This Part

The inclusion of a 128-bit unique serial number simplifies inventory management and security without consuming user memory space. Its robust endurance of 1,000,000 write cycles and 100-year data retention ensures long-term reliability in demanding industrial environments.

Applications

Device Identification
Utilizing the 128-bit unique serial number to provide a globally unique identity for hardware nodes in a network.
Configuration Storage
Storing calibration constants, user preferences, or network credentials in 128 bytes of user-writable EEPROM.
Product Traceability
Ensuring inventory tracking and counterfeit protection through the permanent, factory-set serial number.
Asset Tracking
Integrating into low-power industrial sensors where minimal standby current (6uA) is critical for battery life.

Getting Started

Interface this device with any I2C master using standard wire libraries; the device address is fixed with specific bits for accessing the unique serial number versus the user EEPROM. Ensure a pull-up resistor is present on the SDA and SCL lines, and utilize the hardware Write-Protect pin to prevent accidental data corruption.
