Abstract
This paper suggests a 8-bit RISC microcontroller, which has a 4-stage pipeline architecture. Many low-power design techniques that have been proposed by previous works are adopted into it. The proposed microcontroller consumes only 600㎼ per MIPS for 0.6 ${\mu}{\textrm}{m}$ CMOS process and even lower power of 70㎼ per MIPS for 0.25${\mu}{\textrm}{m}$ process. The RTL level design of this microcontroller is carried out using VHDL. The functional verification is thoroughly done at the gate level using 0.6${\mu}{\textrm}{m}$/0.25${\mu}{\textrm}{m}$ CMOS IDEC standard cell library. This microcontroller contains 7000 NAND gates on a 0.36$\textrm{mm}^2$ die using 0.25${\mu}{\textrm}{m}$ process. Finally the comparison of power consumption with other conventional microcontrollers is provided.
