Microchip Technology's 25AA256, a 262Kbit serial EEPROM, offers a 32Kx8 memory organization. This CMOS device operates across a wide temperature range of -40°C to +85°C and supports SPI bus communication up to 10MHz. It features flexible supply voltage operation from 1.8V to 5.5V, with specific operation at 1.8V minimum at 3MHz. Endurance is rated at 1,000,000 write cycles, and data retention is a minimum of 200 years. The 25AA256T-I-SM16KVAO is supplied in a PDSO8 (SOP8) surface-mount package with a 1.27mm pitch. Typical applications include industrial control systems, automotive electronics, and consumer devices requiring non-volatile data storage. Write protection is available through both hardware and software mechanisms.
