概述

Description

The 24AA1025-I/SN is a 1-kilobit EEPROM (Electrically Erasable Programmable Read-Only Memory) device that utilizes an I²C (Inter-Integrated Circuit) interface for serial communication. It is part of Microchip Technology's 24AA series, designed for applications requiring non-volatile memory storage. The "24AA" prefix indicates it uses a 2-wire I²C protocol, allowing multiple devices to be connected on the same bus.
The 24AA1025-I/SN supports a range of features, including byte and page write capabilities, making it suitable for storing configuration settings, calibration data, or small amounts of user data. It operates at a voltage range of 1.7V to 5.5V, making it versatile for various electronic applications. The device is available in different packages, and its low power consumption makes it ideal for battery-operated devices.
It is commonly used in consumer electronics, industrial applications, and IoT devices where reliable non-volatile storage is required.
