Overview

The 24LC32AT-I/SN is a 32Kbit (4KB) Electrically Erasable PROM designed for low-power non-volatile data storage. It operates across a wide voltage range of 2.5V to 5.5V and utilizes a standard 2-wire I2C serial interface. This memory is ideal for storing configuration constants, calibration data, or user preferences in embedded systems.

Why Choose This Part

This EEPROM features a very low standby current of 1 uA typical, making it suitable for battery-powered applications. It supports a 400 kHz clock frequency for efficient data transfers and provides reliable data retention over a wide temperature range of -40C to +85C.

Applications

Configuration Storage
Retaining device setup parameters and user-defined settings between power cycles.
Calibration Data
Storing sensor offset and gain values for precision analog measurement systems.
Event Logging
Recording small-scale historical data such as error logs or usage counters.
Identification Storage
Holding MAC addresses, serial numbers, and firmware version information for system identification.

Getting Started

To interface with this device, connect the SDA and SCL pins to your microcontroller's I2C bus with appropriate pull-up resistors. Microchip's MPLAB X IDE and the MCC (MPLAB Code Configurator) can generate the necessary I2C drivers for PIC and AVR microcontrollers. Ensure the hardware address pins are tied high or low to match your software address configuration.
