描述 Description

The Microchip 25AA1024 is a 1 Mb Serial EEPROM utilizing theindustry standard Serial Peripheral Interface (SPI) compatible serial bus. Thedevice is organized as one block of 128K 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 ?,?, 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.
