Overview

The Microchip 24LC32A-I/SN is a 32Kbit (4KB) serial EEPROM, offering non-volatile data storage through an I2C interface. This low-power CMOS device operates over a wide voltage range of 2.5V to 5.5V and supports industrial temperature conditions. It is a robust solution for applications requiring reliable data logging or configuration storage.

Why Choose This Part

This EEPROM provides reliable data retention for more than 200 years and offers over 1 million erase/write cycles, ensuring long-term stability for critical data. Its low-power CMOS technology and 1uA typical standby current make it suitable for battery-powered applications. Features like Schmitt Trigger inputs and output slope control contribute to robust performance in noisy environments.

Applications

Getting Started

To get started with the 24LC32A-I/SN, integrate it into your design with an I2C master device, such as a microcontroller. Utilize standard I2C libraries available for your chosen development platform (e.g., Arduino, ESP-IDF, STM32Cube) to read and write data. Ensure proper pull-up resistors are used on the SCL and SDA lines, and connect the write-protect (WP) pin as required by your application.
