FM3 family low power consumption solution by proximity sensor

 

The control of low power consumption is required for devices with long standby time in consumer products, industrial equipment and so on.
FSL 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 proximity sensor and the deep standby mode.

Outline

This solution performs detection of the proximity 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 something separates from the proximity sensor.
  • Then the MCU changes to the active mode and outputs sound, if the proximity sensor detected that something has approached.
