STUSB02E

STUSB02E USB Transceiver General features ■ ■ ■ ■ ■ ■ ■ ■ ■ Supports 1.5Mbps and 12Mbps serial data transmission ESD HBM: ±14kV on D+, D– Lines; ±5kV on VBUS ESD Compliant to IEC-61000-4.2 (Level 3) Separate I/O supply with operation down to 1.6V Integrated speed select termination supply Very low power consumption to meet USB ‘suspend’ current requirements Small QFN16 lead free package No power supply sequencing requirements Software controlled re-enumeration The transceiver also supports Sharing mode when VBUS is not present, which allows the D+/D– lines to be shared with other serial protocols. 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. QFN16 (3mmx3mm) Description The STUSB02E is a single chip USB transceiver that supports both full-speed (12Mbps) and lowspeed (1.5Mbps) operation. 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.

Functional diagram 14/20 STUSB02E Functional description 8 Functional description The STUSB02E is designed to provide USB connectivity in mobile systems where available system supply voltages are not able to satisfy USB requirements. The STUSB02E can operate down to supply voltages of 1.6V. As shown in the circuit above, the STUSB02E 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 1.5KΩ resistor is required to be connected between this pin and the D+ or D– lines to respectively specify full speed or low speed operation. The use of ESD transient protection devices is not required for operation, but is recommended. 15/20 Package mechanical data STUSB02E 9 Package mechanical data In order to meet environmental requirements, ST offers these devices in ECOPACK® packages.
