ABSTRACT
In this work we expose the challenges of interfacing both conventional and new systems with an extremely resource constrained platform. We find that even when attempts are made to utilize an industry standard protocol (I2C), necessary protocol modifications for ultra-low power design means that interfacing remains non-trivial.
We present a functional 0.4mm x 0.8mm ARM Cortex M0 with 3KB of RAM, 24 GPIOs, and an ultra-low power I2C interface. This chip is part of the Michigan Micro Mote (M3) project, which is designed to build a complete software and hardware platform for general purpose sensing at the millimeter scale. We demo an I2C interface circuit allowing commercial hardware to program and interact with the chip and present the beginning of the millimeter scale sensing revolution.

An ultra low power low voltage linear PMU for portable applications
SBCCI '11: Proceedings of the 24th symposium on Integrated circuits and systems designThis paper describes the implementation of a linear power management unit (PMU) for portable devices. The system includes ultra low power current and voltage references, oscillator and 8-bit analog-to-digital converter for power supply monitoring, a ...
FPGA power reduction using configurable dual-Vdd
DAC '04: Proceedings of the 41st annual Design Automation ConferencePower optimization is of growing importance for FPGAs in nanometer technologies. Considering dual-Vdd technique, we show that configurable power supply is required to obtain a satisfactory performance and power tradeoff. We design FPGA circuits and ...
Advances in ultrabook™ platform power management
ISLPED '12: Proceedings of the 2012 ACM/IEEE international symposium on Low power electronics and designIn the beginning (at least the early 90s) PC power management was architected such that it traveled with the PC and would work regardless of the Operating System (OS); you loaded DOS", Windows" or Unix" and the power management just worked. This was ...
