USB 2.0 FS Module
11.3 USB Module Architecture
The USB module block diagram is shown in
transceiver, USB control logic, USB request processor, USB endpoint controller and USB Endpoint
buffer.
11.3.1 USB Transceiver
The USB transceiver is electrically compliant to the Universal Serial Bus Specification 2.0. The on-chip
3.3V regulator provides a stable power source for the termination pull-up resistor. Full speed devices are
terminated with the pull-up resistor on the D+ line.
