Product overview

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 detect the presence of the VBUS voltage and features an internal D+ pull-up resistor implemented in accordance with the 27% resistor ECN. 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.
  • All features

    • Integrated D+ pull-up resistor for FS operation
    • Software controlled re-enumeration
    • Small QFN16 lead free package 3x3 mm2
    • Very low power consumption to meet USB ‘suspend’ current requirements
    • Compliant to USB V2.0 for full-speed (12Mb/s) and low-speed (1.5Mbps) operation
    • ESD Compliant to IEC-61000-4.2 (level 3) on D+, D- lines
    • HBM = ±14kV on D+, D– lines; ±5kV on VBUS
    • Integrated 3.3V output LDO
    • No power supply sequencing requirements
    • Separate I/O supply with operation down to 1.6V
