(I-temp) patented** single I/O UNI/O serial bus. By using 128 x 8 through 2,048 x 8 Bit Organizations Manchester encoding techniques, the clock and data Schmitt Trigger Inputs for Noise Suppression are combined into a single, serial bit stream (SCIO), where the clock signal is extracted by the receiver to Output Slope Control to Eliminate Ground Bounce correctly decode the timing and value of each bit. 100 kbps Max. Bit Rate Equivalent to 100 kHz Clock Frequency Low-voltage design permits operation down to 1.8V (for 11AAXXX devices), with standby and active currents of Self-Timed Write Cycle (including Auto-Erase) only 1 uA and 1 mA, respectively. Page-Write Buffer for up to 16 Bytes The 11XX family is available in standard packages STATUS Register for Added Control: including 8-lead PDIP and SOIC, and advanced pack- - Write enable latch bit aging including 3-lead SOT-23, 3-lead TO-92, 4-lead - Write-In-Progress bit Chip Scale, 8-lead TDFN, and 8-lead MSOP.
