Overview

The AT24C32D-SSHM-B is a 32-Kbit non-volatile serial EEPROM organized as 4,096 words of 8 bits each. It operates over a wide voltage range of 1.7V to 5.5V and utilizes an I2C serial interface capable of speeds up to 1 MHz. This memory is designed for low-power applications, drawing only 6 uA in standby mode.

Why Choose This Part

This EEPROM provides a robust 1 MHz clock frequency for faster data throughput and supports a broad supply voltage of 1.7V to 5.5V, making it compatible with both low-voltage mobile logic and standard 5V systems. Its 8-SOIC package is easy to handle during assembly while maintaining a small footprint.

Applications

Configuration Storage
Storing calibration data, user settings, and network configuration parameters in embedded systems.
Device Identification
Housing serial numbers, MAC addresses, and revision data for hardware identification.
Data Logging
Recording error logs, usage statistics, or sensor event timestamps in small-scale monitoring devices.

Getting Started

Connect the SCL and SDA pins to your microcontroller's I2C bus with appropriate pull-up resistors, typically 4.7k ohms. Use standard Wire libraries in the Arduino ecosystem or I2C HAL drivers in STM32Cube or MPLAB X to perform page writes of up to 32 bytes. Ensure the WP (Write Protect) pin is tied to GND for normal write operations.
