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 QFN16 (3mm x 3mm) detect the presence of the VBUS voltage and features an internal D+ pull-up resistor implemented in accordance with the 27% resistor ECN. 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 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 lowspeed (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.

Functional diagram 14/20 STUSB03E STUSB03E 8 Functional description Functional description The STUSB03E is designed to provide USB connectivity in mobile systems where available system supply voltages are not able to satisfy USB requirements. The STUSB03E can operate down to supply voltages of 1.6V and still meet USB physical layer specifications. As shown in the circuit above, the STUSB03E takes advantage of the USB supply voltage, VBUS, to operate the transceiver. The system voltage, VIF, is used to set the reference voltage used by the digital I/O lines interfacing to the system controller. Internal circuitry provides translation between the USB and system voltage domains. VIF will typically be the main supply voltage rail for the controller. In addition, a 3.3V, 10% termination supply voltage, VPU, is provided to support speed selection. VPU can be disabled or enabled under software control via the CON input. This allows for software-controlled connect or disconnect states. A 1.5K resistor is required to be connected between this pin and the D- line when operating in low speed mode. In full speed mode either an internal pull-up resistor or an external one connected between VPU pin and D+ line can be used; the desired configuration is chosen by tying RSEL pin to VIF or GND. The use of ESD transient protection devices is not required for operation, but is recommended. 15/20 Package mechanical data 9 STUSB03E Package mechanical data In order to meet environmental requirements, ST offers these devices in ECOPACK® packages.
