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. Available in small BCC++16L package 3 mm x 3 mm max thickness 0.80 mm halogen free RoHS compliant package e t le c u d BCC++16L (3 mm x 3 mm) c u d o r P ) s t( The STUSB06E also supports sharing mode when VREG is not present, which allows the D+/Dlines 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.

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, VREG, to operate the transceiver. The system voltage, VCC_IO, is used to set the reference voltage required by the digital I/O lines interfacing to the system controller. Internal circuitry provides translation between the USB and system voltage domains. VCC_IO will typically be the main supply voltage rail for the controller. In addition, a termination supply voltage, VPU, is provided to support speed selection. VPU 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 Table 6 behavior, sometimes, an internal weak pull-up resistor is connected instead. ) s t( c u d o r P The VREG 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. e t le o s b 5.1 Power supply configurations O ) The STUSB06E supports four power supply configurations. Operating mode: Both VCC_IO and VREG are present. This is the standard configuration for normal operation. s ( t c Disable mode: VREG is connected while VCC_IO is disconnected. D+ and D- pins are threestated and the power consumption is reduced. u d o Sharing mode: VCC_IO is connected while VREG is disconnected. HIGHZ input is left floating or driven low. D+ and D- pins are three-stated and the differential data lines can be shared with signals of up to 3.6 V. Power consumption is reduced in this mode. The pins VP and VM are driven high and pin RCV is driven low. r P e s b O t e l o High-Z mode: VCC_IO is connected while VREG is disconnected. High-Z input must be driven High. Every output pin is three-stated and the differential data lines can be shared with signals of up to 3.6 V. Power consumption is reduced in this mode. Refer to the functional tables for more details regarding pin's status in these power modes. Charger detection mode: An embedded weak pull-up resistor of 150 kΩ is used to implement a resistive detection mechanism. According to USB Battery Charger Specification rel.1.1, this method will reliably detect: – Rechargeable Portable Device attached to Dedicated Charger Port or – Rechargeable Portable Device attached to Standard Host Port. 11/20 Functional description Figure 3.
