TM4C129DNCPDT: Check this part for USB to 8 UART bridge

MAHENDER SHARMA
Prodigy 30 points

Part Number: TM4C129DNCPDT

Dear team,

We are trying to develop 8 port USB to UART bridge, s for that we would need support of USB CDC communication class.

Since CDC communication class requires 3 endpoints each for every COM Port, we would be requiring at least 3*8=24 endpoints support in USB.

But the part TM4C129DNCPDT has 32 endpoints out of which only 14 are configurable. 

but in the explanation of the the USB description  there is only 14 end point mention in which 7 in and 7 out are configurable.

but also in integrated USB DMA with bus master capability. 8 RX and 8 TX endpoint mentioned . 

So can we use this all endpoint .as a configurable .

So please suggest this part is suitable for us  if not please suggest suitable part for my application.
