Data Transfer Manager Offloads Low Power Microcontroller

Silicon Labs delivered precision analog microcontroller based on the Arm Cortex-M3 (see Precision Analog 32-bit Micro Uses A Crossbar Interconnect) earlier this year. The latest 50 MHz Precision32 SiM3L1xx (Fig. 1) products incorporate a number of new features including a DC-DC buck converter initially found on their 8-bit platforms (see Integrated DC-DC Buck Converter Reduces 8-bit Power Requirements). …

Reliability vs. power in embedded wireless applications – What datasheets don’t say

The measure of an embedded wireless application’s power consumption, however, is not the simple sum of its parts as one might think.  While this has been the typical means of comparing and selecting components for a given application, this basic means of obtaining a quantifiable metric to compare fails to adequately capture the true measure of how these components will …
