MCHP24AA32A-I/SN

Overview

The 24AA32A-I/SN is a 32-Kbit I2C serial EEPROM designed for low-power, non-volatile data storage applications. It features a wide operating voltage range from 1.7V to 5.5V and is organized as 4096 bytes of 8-bit memory. This component is optimized for industrial environments with a temperature rating of -40C to 85C and maintains a very low standby current of 1 microamp.

Why Choose This Part

This EEPROM offers excellent power efficiency with a typical run current of only 1mA and a standby current of 1uA. It supports standard I2C clock frequencies up to 400 kHz and is housed in a standard 8-pin SOIC package, making it a reliable and widely compatible choice for low-voltage systems.

Applications

Getting Started

To interface with the 24AA32A-I/SN, connect the SDA and SCL lines to your microcontroller's I2C bus with appropriate pull-up resistors. Set the hardware address pins (A0, A1, A2) to define the bus address, and ensure the WP pin is tied to ground if write protection is not required. Logic implementation is straightforward using standard I2C libraries like the Wire library for Arduino or Microchip's MCC for PIC microcontrollers.
