The Microchip Technology AT25256B-SSHL-T-537 is a 256 Kbit serial electrically erasable programmable read-only memory (EEPROM) organized as 32K words by 8 bits. This CMOS device supports the Serial Peripheral Interface (SPI) bus protocol, enabling synchronous operation at frequencies up to 20 MHz. It offers flexible voltage operation, functioning from 4.5V to 5.5V at 20 MHz, 2.5V to 5.5V at 10 MHz, and 1.8V to 5.5V at 5 MHz. The AT25256B features a data retention time of 100 years and an endurance of 1 million write cycles. It includes both hardware and software write protection mechanisms. Packaged in an 8-lead small outline package (PDSO8), this component is suitable for applications in industrial, automotive, and consumer electronics where reliable non-volatile data storage is required.
