USB3370

Microchip's USB3370 is a family of Hi-Speed USB 2.0 Transceivers that provide a physical layer (PHY) solution well-suited for portable electronic devices. Both commercial and industrial temperature applications are supported.

Several advanced features make the USB3370 the transceiver of choice by reducing both eBOM part count and printed circuit board (PCB) area. Outstanding ESD robustness eliminates the need for external ESD protection devices in typical applications. The internal Over-Voltage Protection circuit (OVP) protects the USB3370 from voltages up to 30V on the VBUS pin. By using a reference clock from the Link, the USB3370 removes the cost of a dedicated crystal reference from the design. The USB3370 includes integrated 3.3V and 1.8V regulators, making it possible to operate the device from a single power supply.

The USB3370 is optimized for use in portable applications where a low operating current and standby currents are essential. The USB3370 operates from a single supply and includes integrated regulators for its supplies. The USB3370 also supports the USB Link Power Management protocol (LPM) to further reduce USB operating currents.

The USB3370 also includes family is enabled with Microchip's RapidCharge AnywhereTM which supports USB-IF Battery Charging 1.1 for any portable device. RapidCharge AnywhereTM provides three times the charging current through a USB port over traditional solutions which translate up to 1.5Amps via compatible USB host or dedicated charger. In addition, this provides a complete USB charging ecosystem between device and host ports such as Dedicated Charging Port (DCP), Charging (CDP) and Standard (SDP) Downstream Ports. Section 5.9 describes this is further detail.

The USB3370 meets all of the electrical requirements for a Hi-Speed USB Host, Device, or an On-the- Go (OTG) transceiver. In addition to the supporting USB signaling, the USB3370 also provides USB UART mode.

USB3370 uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB transceiver to the Link. ULPI uses a method of in-band signaling and status byte transfers between the Link and PHY to facilitate a USB session with only twelve pins.

The USB3370 uses Microchip’s “wrapper-less” technology to implement the ULPI interface. This “wrapperless” technology allows the PHY to achieve a low latency transmit and receive time. Microchip’s low latency transceiver allows an existing UTMI Link to be reused by adding a UTMI to ULPI bridge. By adding a bridge to the ASIC the existing and proven UTMI Link IP can be reused.
