Overview

The AT24C32D-SSHM-T is a 32-Kbit non-volatile serial EEPROM organized as 4,096 bytes of 8 bits each. It operates over a wide voltage range of 1.7V to 5.5V and utilizes an I2C-compatible serial interface capable of speeds up to 1 MHz. This component is designed for low-power industrial and commercial applications requiring reliable data retention in a compact 8-SOIC package.

Why Choose This Part

This device features an ultra-low standby current of only 6 uA, making it suitable for battery-powered designs. It supports a high-speed 1 MHz clock frequency for rapid data transfers and provides hardware write protection to prevent accidental data corruption. The 8-SOIC package offers a familiar footprint for easy manufacturing and prototyping.

Applications

Microcontroller Configuration Storage
Ideal for storing calibration constants, boot parameters, and user settings that must persist across power cycles.
Asset Tracking and Identification
Used in modular systems to store serial numbers, hardware revision data, and manufacturing information for identification via I2C.
Sensor Data Logging
Provides sufficient capacity for periodic logging of environmental data or system event timestamps in low-duty-cycle applications.
Consumable Verification
Used within printer cartridges or medical disposables to track usage counts and prevent unauthorized refills.

Getting Started

To interface with this EEPROM, connect the SCL and SDA lines to a microcontroller I2C peripheral with appropriate pull-up resistors. Ensure the WP (Write Protect) pin is tied to GND for standard read/write operations or to VCC to protect the memory array. Library support is widely available for Arduino, STM32 HAL, and Microchip MCC environments.
