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.

USB Transceiver

QFN16 (3mmx3mm)

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.
