11AA02E48T-I/TT

The Microchip Technology Inc. 11AA02E48/ 11AA02E64 (11AA02EXX) device is a 2 Kbit Serial Electrically Erasable PROM. 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 11AA02EXX is available in standard 8-lead SOIC and 3-lead SOT-23 packages.
