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 VBUS. The

transceiver has an integrated voltage detector to

detect the presence of the VBUS voltage and

features an internal D+ pull-up resistor

implemented in accordance with the 27% resistor

ECN.

The STUSB03E also supports Sharing mode

when VBUS 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.
