Manufacturer: Microchip
The AT25256B-SSHL-B is a serial EEPROM from Microchip. Capacity is 256 Kbit. It communicates over SPI. Supply voltage is 1.7 – 5.5 V. Offered in the SOIC package. Rated operating temperature is -40 to +85 °C. Parameters above are taken from the manufacturer datasheet; confirm the current revision before finalising a design.
Overview
Microchip lists the AT25256B-SSHL-B as a 256 Kbit SPI serial EEPROM with a supply of 1.7 – 5.5 V, operation across -40 to +85 °C and SOIC packaging.
When the design is finalised, the interface mode follows the part number, so the suffix should be matched to the bus actually used on the board.
