USB OTG module
This transceiver complies with the USB specification;
● Universal serial bus specification Rev 2.0
● On the go supplement to the USB specification Rev 1.0-a
● Car kit interface specification (see: OTG transceiver specification Rev 0.92)
The USB OTG Transceiver has two modes: USB mode and UART mode. It includes:
● Full and low speed transceiver (12 Mbit/s and 1.5 Mbit/s data rate)
● Support data line and VBUS pulsing session request
● Contains Host Negotiation Protocol (HNP) command and status register
● Charge pump regulator (5 V at 100 mA) to supply VBUS line of the USB cable
● VBUS pull-up and pull-down resistors as defined by Session Request Protocol (SRP)
● VBUS threshold comparators
● VUSB LDO internal regulator which provides power supply for the bus driver and
receiver.
● ID line detector and interrupt generator
● Dedicated I²C serial control interface
The transceiver complies with USB specification if Vbat is greater than 3.2 V.
