Microchip Technology's AT25256B-SSHL-T-899 is a 262,144-bit serial EEPROM organized as 32K x 8 bits. This CMOS device supports SPI serial interface up to 20 MHz clock frequency and offers flexible voltage operation from 2.5V to 5.5V at 10 MHz, and 1.8V to 5.5V at 5 MHz. With a data retention of 100 years and an endurance rating of 1,000,000 write cycles, it is designed for demanding applications. The AT25256B features hardware and software write protection and operates across an industrial temperature range of -40°C to +85°C. It is housed in a standard 8-lead SOIC package (PDSO8) with a 1.27mm pitch, suitable for surface-mount assembly. This component is commonly utilized in automotive, industrial control, and consumer electronics systems.
