STUSB06E
3.3 V USB transceiver
BCC++16L
(3 mm x 3 mm)
Description
The STUSB06E is a single chip transceiver that
complies with the physical layer specifications of
the Universal Serial Bus (USB) v2.0 standard. It is
powered by external 3.3 V supply and has an
integrated 150 kΩ resistor to implement charger
detection with weak pull-up method.
The STUSB06E also supports sharing mode
when V
lines to be shared with other serial protocols.
It supports both full-speed (12 Mbps) and lowspeed (1.5 Mbps) operation. It is also designed to
operate down to 1.6 V so that it is compatible with
lower system voltages of most portable systems,
which include cell phones, PDAs and MP3
players.

STUSB06E Functional description
5 Functional description
The STUSB06E is designed to provide USB connectivity in mobile systems. The
STUSB06E can operate down to digital I/O supply voltages of 1.6 V and still meet USB
physical layer specifications. The STUSB06E takes typical 3.3 V supply voltage, V
operate the transceiver. The system voltage, V
, is used to set the reference voltage
CC_IO
required by the digital I/O lines interfacing to the system controller. Internal circuitry provides
translation between the USB and system voltage domains. V
will typically be the main
CC_IO
supply voltage rail for the controller.

, to
In addition, a termination supply voltage, V
can be disabled or enabled under software control via the SOFTCON input. This allows for
software-controlled connect or disconnect states. A 1.5 kΩ resistor is required to be
connected between this pin and the D+ (full-speed) or D- (low-speed) line; according to
Ta bl e 6 behavior, sometimes, an internal weak pull-up resistor is connected instead.
The V
Input voltage ranging form 3 V to 3.6 V must be provided as main power supply.

The STUSB06E also supports sharing mode in which some pins are made 3-state to allow
data lines sharing.
