A 58-μW Single-Chip Sensor Node Processor Using Synchronous MAC Protocol

Abstract

In this paper, we propose a single-chip ultra low-power sensor node processor with a synchronous media access control (MAC). It is comprised of a transceiver, i8051 micro processor, and dedicated MAC processor. The test chip occupies 3x3mm^2 in a 180-nm CMOS process, including 1.38M transistors. The power is 58.0μW under a network environment.
