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.

Differential receiver output. Stable output during SE0. This pin has an internal 220 kΩ pull-down to ground when HIGHZ=”H” only.

Standard Mode: USB D+ receiver output. This pin has an internal 220 kΩ pull-down to ground when HIGHZ=”H” only.

Standard Mode: USB D- receiver output. This pin has an internal 220 kΩ pull-down to ground when HIGHZ=”H” only.

Normally used as Suspend input (active high). Puts the transceiver in low power consumption mode. Functionality can change depending on status of SPEED# and SOFTCON pins. See Ta bl e 1 2 for more details.

Sets to high impedance for production flash. This pin has an internal 220 kΩ pulldown to ground always connected.

Normally used as Speed selection input. A logic LOW adjusts the slew rate of D+/DUSB differential signals for Full-speed operation. Set to HIGH for Low-speed operation. Functionality can change depending on status of SUSPEND and SOFTCON pins. See Ta bl e 1 2 for more details.

Standard Mode: Force single-ended zero data input. This pin has an internal 220 kΩ pull-down to ground when HIGHZ=”H” only.

Analog supply voltage input (3.0 V to 3.6 V). Left floating brings the device into sharing mode.

Data line pull-up supply voltage. Connect an external 1.5 kΩ resistor to D+ (fullspeed) or D- (low-speed). Pin output is controlled by SUSPEND, SPEED# and SOFTCON inputs.

Normally used as Software controlled enumeration pin: controls the status of VPU pin and the connection of internal weak pull-up resistor. LOW: VPU floating (SUSPEND=”0” or “1”). HIGH: VPU = 3.3 V. Functionality can change depending on status of SPEED# and SUSPEND pins. See Ta bl e 1 2 for more details.
