Description

The Microchip AT24CS01 is a 1 Kb Serial EEPROM utilizing an I2C (2-wire) serial interface. The device is organized as one block of 128 x 8 and is optimized for use in consumer and industrial applications where reliable and dependable nonvolatile memory storage is essential. The EEPROM is available in a variety of space-saving packaging options. The AT24CS01 features a 128 bit serial number that is programmed and permanently write protected during the Microchip manufacturing process. This unique identifier is separate from the main 1Kb memory array and eliminates the time consuming step of performing and ensuring serialization of a product on a manufacturing line. The 128-bit serial number is guaranteed unique across the entire CS series of Serial EEPROM products.
