25.8 x 13.4 x 2.2 mm SMT

ABBTM-NVC-MDCS42A

USB

This is a full speed (12M bits/s) USB interface for communicating with other compatible digital devices. The module

acts as a USB peripheral, responding to request from a master host controller, such as a PC.

The USB interface is capable of driving a USB cable directly. No external USB transceiver is required. The device

operates as a USB peripheral, responding to requests from a master host controller such as a PC. Both the OHCI and the

UHCI standards are supported. The set of USB endpoints implemented can behave as specified in the USB section of the

Bluetooth specification v2.0+EDR or alternatively can appear as a set of endpoints appropriate to USB audio devices

such as speakers.

The module has an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when module is ready to

enumerate. It signals to the USB master that it is a full speed (12Mbit/s) USB device.

Note:

USB_ON is only used when the firmware need an input to detect if USB is connected and the USB function shall be

enabled. In such case it is shared with the module PIO terminals. If detection is not needed (firmware already runs with

USB, such as USB DFU or USB CDC), USB_ON is not needed.
