FM3 family low power consumption solution by illumination sensor

 

The control of low power consumption is required for devices with long standby time in consumer products, industrial equipment and so on. Spansion provides the most suitable MCU in FM3 family to control for low power consumption at the system standby.

This solution uses FM3 family "MB9AF132L" and performs the control of low power consumption at the system standby, and so on by operating together with the illumination sensor and the deep standby mode.

Outline

This solution performs the detection of the illumination sensor, the control of low power consumption at the system standby by the deep standby mode and so on using FM3 family "MB9AF132L".

  • The MCU changes into the deep standby mode, if the illumination sensor has detected more than a certain lux.
  • Then the MCU changes to the active mode, if the illumination sensor has detected less than a certain lux.
