Can we use high-speed on FRDM K64 with additionnal chips

flauberttagu — Mon, 13 Jul 2020 22:14:10 GMT

Hello,

I want to know if the FRDM K64 which is using only full-speed USB could work with high-speed chips like the Texas instrument TUSB216RWBT.
If yes, will it be possible to increase the speed.

Thank you for your help in advance.

Regards.

Hi,

1 Yes.

2 No. Full-speed and low speed.

Have a great day,
TIC

The K64 can only be used for low or full-speed USB device/host/OTG. To use it at high speed an external HS USB controller would be needed (eg. via SPI).
If your design needs HS USB operation it is simpler to move to the K65/K66 instead, which then allows one low/full speed OTG interface plus one low/full/high speed one.

Hello,

Is it possible to move easily from a code develop for the K64 to the K65 or K66? Are those two ARM compatible to K64 in terms of computing?

Thx is andvance.
