Hi,

I have two questions about fx3.

Q1: When the CPU is done by software CPU resets(not whole device reset) , are the status of all I/O pins retained?

Q2: What is the maximum current consumption in the following cases?
 1.current consumption while RESET# is Low
 2.current consumption during RESET RECOVERY TIME

Hello, Nagata san,

Responding to Q2)
->The current consumption shall not exceed the values provided in Table 8 of the datasheet:

CurrentConsumption.png

Therefore the current through VDD + AVDD is < 200 mA
and the current through the USB voltage supply is < 60 mA
When sizing the LDO, please take these values as a reference.

Best regards,
Pablo
