Description
The STUSB02E is a single chip USB transceiver that supports both full-speed (12Mbps) and low speed (1.5Mbps) operation. It has an integrated 5V to 3.3V regulator which allows direct powering from the VBUS. The transceiver has an integrated voltage detector to detect the presence of the VBUS voltage.
The transceiver also supports Sharing mode when VBUS is not present, which allows the D+/D–lines to be shared with other serial protocols.
It is also designed to operate down to 1.6V so that it is compatible with lower system voltages of most portable systems, which include PDAs, MP3 Player and Cell phones.
