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 V_BUS. The transceiver has an integrated
voltage detector to detect the presence of the
V_BUS voltage.
USB Transceiver
QFN16 (3mmx3mm)
The transceiver also supports Sharing mode
when V_BUS 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.
