The Microchip 256 Kb Serial EEPROM utilizing the industry standard Serial Peripheral Interface (SPI) compatible serial bus. The device is organized as one block of 32,768 x 8-bit and is optimized for use in consumer electronics, industrial, medical, and automotive applications where reliable and dependable non-volatile memory storage 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.
Supports SPI modes 0 and 3
Up to 20 MHz clock frequency
Self-Timed Erase and Write Cycles 5 ms max
Data retention 100 years
More than 1 million erase or write cycles
