Abstract :
We present an ultra-low-power Microcontroller Unit (MCU) with an embedded atom switch ROM, which performs a 0.33-1.2 V operation voltage and 46.8-μA/MHz active current (or 18.26-μW/MHz active power). The MCU is fabricated by the hybrid of Silicon-On-Thin-Buried-oxide (SOTB) CMOS and bulk CMOS [1]. The SOTB CMOS with a body-bias voltage control realizes a high drivability up to 40-MHz operation at 0.54 V and small sleep power (0.628 μW), simultaneously.
