Abstract：Objective To meet the special requirement of Implantable Medical Device (IMD), this study
designed flexible Micro Control Units (MCU) of low-power consumption and high efficiency to achieve
optimal use of battery power. Methods Based on the analysis of IMD mainstream technology, the design
of MCU based on 0.18 μm CMOS technical standard was optimized by clock gating, power gating,
instruction set improvement, DMA optimization for data paths, etc. Results The die area of the designed
MCU was 1.4 mm×0.8 mm, and chip memory owned 79.1 K equivalent gates and 6.6 K onchip
memory. Given a 0.9 V power supply, MCU power consumption was 165 μW, and it could be reduced
to 42 μW in idle state. Conclusion The designed MCU can be remotely programmed with low power
consumption and high efficiency, which makes the IMD more flexible and energy saving to well perform
its monitoring or stimulating function during disease surveillance or treatment.
