Libraries of Standard Cells: Always-on logic libraries

SESAME BiV - 10 tracks

TSMC 55 LLeF, SESAME BIV, a new thick oxyde based standard cell library for ultra low leakage logic design and/or direct battery connection through the use of a patented flip flop.

Benefits

    • No need for a voltage regulator Cells designed with 3.3 V thick-oxyde transistors to support a wide operating voltage range from 3.3 V +/-10% to 1.2 V +/-10% Custom characterization corners down to 1.10 V +/-10% can be provided Ideal for always on clock islets (RTC) and always on functional islets (voice recognition?) Low dynamic power with ultra-low leakage Leakage reduction of 1/700 for a 5,000 gates islet implemented with BIV at 3.3 V, compared to a conventional HVT library operating at 1.2 V Support of low voltage retention down to 0.85 V Higher density compared to HVT library combined with voltage regulator 8-track cells 7X gain in density for a 5,000 gates islet implemented with BIV at 3.3 V, compared to a conventional HVT library operating at 1.2 V SoC Integration secured and simplified from 3.3 V to 1.2 V Selection of the optimal characterization corners to maintain speed, reliability and consumption at low voltage Full set of high-low and low-high level shifters isolated or not
