Abstract

This paper presents an ultra-low-power micro controller unit (MCU) built as a system-on-chip (SoC) that comprises of a 3-stage pipelined 16b MSP430 CPU, an integrated clock and power-management unit, analog/digital peripherals and embedded FeRAM memory for fast write capability. The SoC is fabricated in 0.13μm CMOS with 5 Cu metal layers. Two additional mask layers are required to include the FeRAM memory.
