25LC040AT-I/SN SPI Serial EEPROM Memory IC 10 MHz 4-Kbit
The 25LC040AT-I/SN is a 4-Kbit (512 x 8) SPI Serial EEPROM manufactured by Microchip Technology, designed for low-power, compact data storage in embedded systems. Operating at a voltage range of 1.7V to 5.5V, it supports industrial-grade temperature tolerance (-40°C to +125°C), making it ideal for automotive, industrial automation, and consumer electronics applications. The device communicates via a 4-wire SPI interface (Serial Clock, Data Input, Data Output, and Chip Select), enabling easy integration with microcontrollers and processors. Its 100,000 write/erase cycle endurance and 200-year data retention ensure long-term reliability, while its page-write capability (16-byte maximum per operation) optimizes efficiency for frequent data updates.
