View Datasheet Manufacturer Site View Pricing & Stock

The Microchip Technology Inc. 11AA02UID is a 2 Kbit Electrically Erasable PROM with a pre-programmed, 32-bit unique ID. This serial number is unique across all UID-Family of EEPROMs. The ID is Scalable to 48-bit, 64-bit, 128-bit, 256-bit, and other lengths. The device is organized in blocks of x8-bit memory and support the patented* single I/O UNI/O® serial bus. By using Manchester encoding techniques, the clock and data are combined into a single, serial bit stream (SCIO), where the clock signal is extracted by the receiver to correctly decode the timing and value of each bit. Low-voltage design permits operation down to 1.8V, with standby and active currents of only 1 uA and 1 mA, respectively. The 11AA02UID is available in standard 8-lead SOIC and 3-lead SOT-23 packages.
