AT25320B-SSHL-B

The Microchip AT25320B is a 32 Kb Serial EEPROM utilizing theindustry standard Serial Peripheral Interface (SPI) compatible serial bus. Thedevice is organized as one block of 4096 x 8-bit and is optimized for use in consumer electronics, industrial, medical,and automotive applications where reliable and dependable nonvolatile memorystorage is essential. Software write protection allows the user to protect ¼,½, or the entire memory array. A hardware write protect pin is also provided,which additionally protects against inadvertent writes to the status register.The EEPROM is available in a variety of space-saving packaging options.
