IoT Sensor Micros Need to Sip Power | Electronic Design
The typical way to minimize power requirements is to run at full speed for as little time as possible and power down at other times. These days, most micros have a range of power-down modes with different power-utilization features that developers can take advantage of depending on the application. Some may only need to run the real-time clock (RTC), while others may have to maintain some or all of the RAM contents.
These methods usually help with almost any microcontroller, but what other options do developers have when choosing a low power platform?
Microcontroller chip designers generally choose technologies that will minimize power requirements while providing performance. Each iteration tends to improve power utilization, but some techniques offer significant advantages over the conventional method.
