25LC040A-I/P General Description

The Microchip 25LC040A is a 4 Kb Serial EEPROM utilizing theindustry standard Serial Peripheral Interface (SPI) compatible serial bus. Thedevice 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 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 and memory array. The EEPROM is available in a variety of space-savingpackaging options.
