MCHPAT25M02-SSHD-T
Overview
The AT25M02-SSHD-T is a high-density 2Mbit SPI Serial EEPROM from Microchip Technology, organized as 256K x 8 bits. It operates across a wide voltage range of 2.5V to 5.5V and supports SPI modes 0 and 3 with clock frequencies up to 5 MHz. Designed for high reliability, it offers a 1,000,000-cycle write endurance and data retention for over 100 years.
Why Choose This Part
This device features a large 256-byte page write buffer and a fast self-timed write cycle of 10ms, improving throughput for large data sets. It includes hardware and software write protection mechanisms, such as a dedicated WP pin and block protection bits, alongside robust ESD protection exceeding 4,000V.
Applications
Key Specifications
Getting Started
To interface with this EEPROM, configure your MCU SPI peripheral for Mode 0 or 3 and ensure the CS line is toggled correctly for every instruction. Microchip provides the MPLAB XC8/XC16 compilers and specialized libraries to handle SPI EEPROM communication, and the part can be evaluated on any standard breadboard using a SOIC-to-DIP adapter.
