STR755 USB pins

Hi chaps,

The STR755 doesn't have a USB peripheral. In the LQFP100 package, there are USB pins. Does anyone know their function when there's no USB peripheral in the device? I presume this carries through to the STR752 too.

Cheers,

Peter

Hello,

For the 64 pin package, pins 41 and 42 are shared with USB and CAN. depending on device part number. For example, the STR752FRx only CAN is available. The 41& 42 pins are mapped to P0.15/CAN_TX and P0.14/CAN_RX.

In addition, the non available pins on LQPFP64 and LFBGA64 packages are internally tied to low level.

Regards.

Dear peterwrigley,

For the LQFP100 package, when there's no USB peripheral in the device as STR755FVx part number, the corresponding USB pins should be left unconnected and not used.

Thanks.
