Suggestions for reducing FX2 power consumption for battery-powered applications

Version 1
    Question: What are some suggestions for reducing the CY7C68013 FX2 power consumption in portable battery-powered applications?



    Some suggestions are:

    1) Implement some circuitry to shut off power to the FX2 when disconnected from the PC.
    2) Ensure that there are no floating unused input pins. These can be tied to GND if they will never be configured as outputs.
    3) Run the CPU and IFCLK at lower speeds when the device is not connected to the PC.
