The device is - Scalable to 48-bit, 64-bit, 128-bit, 256-bit, organized in blocks of x8-bit memory and support the and other lengths patented* single I/O UNI/O serial bus. By using Single I/O, UNI/O Serial Interface Bus Manchester encoding techniques, the clock and data Low-Power CMOS Technology: are combined into a single, serial bit stream (SCIO), - 1 mA active current, typical where the clock signal is extracted by the receiver to correctly decode the timing and value of each bit. - 1 A standby current (max.) 256 x 8 Bit Organization Low-voltage design permits operation down to 1.8V, Schmitt Trigger Inputs for Noise Suppression with standby and active currents of only 1 uA and 1 mA, respectively. Output Slope Control to Eliminate Ground Bounce The 11AA02UID is available in standard 8-lead SOIC 100 kbps Max. Bit Rate Equivalent to 100 kHz and 3-lead SOT-23 packages.
