Microchip Technology's 25AA256T-I-SM16KVXX is a 262 Kbit (32K x 8) serial EEPROM utilizing advanced CMOS technology. This device operates from a single 1.8V to 5.5V supply, with full speed operation at 3MHz achievable at the lower supply bound. The 25AA256 family offers a SPI-compatible serial interface, supporting clock frequencies up to 10MHz. Key features include a data retention of 200 years and an endurance rating of 1,000,000 write cycles. The component is housed in a standard 8-lead PDSO package with a 1.27mm pitch, suitable for surface-mount applications. It supports both hardware and software write protection mechanisms. This EEPROM is widely implemented in automotive, industrial, and consumer electronics for data storage and configuration.
