概述

Description

The 25AA02E48T-I/OT is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. It features a 2Kb (256 x 8 bits) memory capacity and operates on a 1.8V to 5.5V power supply, making it suitable for low-power applications. The device communicates via the I2C (Inter-Integrated Circuit) protocol, allowing multiple devices to be connected on the same bus.
Key features include:
- Fast write speed, with page write capabilities.
- Endurance of up to 1 million write cycles per memory cell.
- Data retention of up to 200 years.
- Small footprint, ideal for space-constrained applications.
It is commonly used in applications such as configuration storage, calibration data, and firmware settings in consumer electronics, automotive, and industrial devices. The "I/OT" in the part number signifies that it is offered in a tape and reel package for automated assembly. Overall, the 25AA02E48T-I/OT is a versatile solution for non-volatile memory storage needs.
