The
Microchip 25AA040A is a 4 Kb Serial EEPROM utilizing the industry
standard Serial Peripheral Interface (SPI) compatible serial bus. The device is
organized as one block of 512 x
8-bit and is optimized for use in consumer electronics, industrial, medical,
and automotive applications where reliable and dependable nonvolatile 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 and memory array. The EEPROM is available in a variety of space-saving
packaging options.
