概述

Description

The 24LC128T-I/ST is a 128 Kbit (16 Kbyte) I²C EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. This non-volatile memory device is used for storing data without requiring a continuous power supply. It operates on a supply voltage range of 1.8V to 5.5V and features a 2-wire I²C interface for communication, allowing multiple devices to be connected on the same bus.
The 24LC128T-I/ST supports fast-mode (up to 400 kHz) I²C communication and is available in various packages, including the 8-pin SOIC. It offers a write cycle time of approximately 5 ms and supports page write operations, enabling multiple bytes to be written in a single operation. This makes it suitable for applications requiring data logging, configuration settings, and other scenarios where data retention is critical after power loss. The device also features built-in write protection and is ideal for consumer electronics, automotive, and industrial applications.

Features
