AT24CS32中文资料32Kb I2C compatible 2-wire Serial EEPROM with Pre-programmed Serial Number数据手册Microchip规格书

描述 Description

The Microchip AT24CS32 is a 32 Kb Serial EEPROM utilizing an I2C (2-wire) serial interface. The device is organized as one block of 4,096 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 AT24CS32 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 32Kb 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.
