Abstract :
In a battery-powered device, power consumption determines the operation time and weight of the overall system. In this paper, a 10 MHz ultra-low voltage SPARK 32-bit RISC microcontroller is proposed, with low power consumption which prolongs operation time and satisfies low end applications in the meantime. The design is carried out with the TSMC 65 nm LP CMOS process, and post-layout simulation indicates the SPARK microcontroller is capable of operating at 10 MHz, and consuming 0.7 mW from a 0.45 V supply. The overall chip layout area is 920×920 μm2.
