STUSB03E
USB Transceiver
General features
■ Compliant to USB V2.0 for full-speed (12Mb/s)
and low-speed (1.5Mbps) operation
■ HBM = ±14kV on D+, D– lines; ±5kV on VBUS
■ ESD Compliant to IEC-61000-4.2 (level 3) on
D+, D- lines
■ Separate I/O supply with operation down to
1.6V
■ Integrated 3.3V output LDO
■ Very low power consumption to meet USB
‘suspend’ current requirements
■ Small QFN16 lead free package 3x3 mm²
■ No power supply sequencing requirements
■ Software controlled re-enumeration
■ Integrated D+ pull-up resistor for FS operation
Description
The STUSB03E is a single chip transceiver that
complies with the physical layer specifications of
the Universal Serial Bus (USB) v2.0 standard. 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
QFN16 (3mm x 3mm)
detect the presence of the V_BUS voltage and
features an internal D+ pull-up resistor
implemented in accordance with the 27% resistor
ECN.
The STUSB03E also supports Sharing mode
when V_BUS is not present, which allows the D+/D–
lines to be shared with other serial protocols.
It supports both full-speed (12Mbps) and low-
speed (1.5Mbps) operation. 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.
