F28M35H52C: mini IO for USB function

user5411045

Part Number: F28M35H52C
Other Parts Discussed in Thread: TMDSCNCDH52C1, C2000WARE

There are 6 IO for onre USB in demon board: M3_USB0DM,M3_USB0DP,M3_USB0PFLT,M3_USB0VBUS,M3_USB0EPEN,M3_USB0ID.

While we don't need so many function,we just need mini function:normal communication,Which are necassary and which are not?how to setup these IO?

Do you have demon schematics for mini usb fcunction?

Hi,

Are you meaning the TMDSCNCDH52C1 controlCard? You can find the schematic within c2000ware at the directory below. The USB schematic is on page 3.

i know this schematci,while i meanthat there are 6 pins for usb,it cost much resource. Minimum io should be less, are M3_USB0PFLT、 PF6_GPIO38、PC5_GPIO69、PG6_GPIO46 pins necessary for normal communication?i just need basic communication without protection for USB.

M3_USB0PFLT is USB0PFLT、 PF6_GPIO38 is USB0VBUS、PC5_GPIO69 is USB0EPEN、PG6_GPIO46 is USB0ID.

Hi,

Standard Type A or B USB is only 4 pin if you're wanting to use that. Then the only GPIOs used are for D+ and D-, the other two pins being USB_Vcc and ground.

What's shown in the schematic is micro USB, which has the ID pin addition (for On-the-Go).

Best,
Kevin
