The Microchip AT21CS11-STU10-T is a 1 Kb Serial EEPROM utilizing theSingle-Wire bus. Only two pins are needed to access the device: SI/O and GND.The SI/O signal is a combination data and power line, providing power to thedevice with a parasitic power scheme. The device is organized as one block of 128x 8 and is optimized for use in consumer and industrial applications wherereliable and dependable nonvolatile memory storage is essential. The EEPROM isavailable in a variety of space-saving packaging options.
The AT21CS11-STU10-T features a 256-bit Security register whichincludes a 64-bit serial number. The device also features manufacturer IDsupport in which the device responds with a unique value for density andrevision information.
