概述

Description

The CAT24C02WI-GT3 is a 2-kilobit (256 x 8) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) device manufactured by ON Semiconductor. It operates over a voltage range of 1.7V to 5.5V, making it suitable for low-power applications. The device features a 2-wire I2C interface for communication, allowing multiple devices to be connected to a single bus, which simplifies design and reduces pin count.
Key features include a programmable write protection, fast write cycles (typically 5 ms), and the ability to support up to 1 million write/erase cycles. The CAT24C02WI-GT3 is ideal for applications requiring non-volatile storage, such as configuration settings, calibration data, and small data logs in consumer electronics, automotive, and industrial devices. Its compact size and low power consumption make it suitable for space-constrained and battery-operated equipment.
