Hi Friends,
Here I am attaching the datasheet of an MCU of STMicroelectronics and a typical pin configuration of a USB 2.0.
PA11 and PA12 of the controller are assumed for USB_DM and USB-DP respectively.
Can I directly connect those pin to the USB through a series 15R resistor and a TVS Diode in parallel to protect those data lines?.
Some images from google suggest that we need a pull up of 1.5K to the D+ line and I am not very sure about it.
Would someone be able to explain this to me?.
