USB3343-CP-TR

The USB3343-CP-TR from Microchip Technology is a Hi-Speed USB 2.0 transceiver, providing a physical layer (PHY) solution suitable for portable electronic devices. It supports both commercial and industrial temperature applications, operating from -40°C to 85°C.

This transceiver features a 1/1 driver configuration and supports the USB 2.0 protocol. It is designed for surface mount installation in a 24-VFQFN Exposed Pad package. The device offers 150 mV of receiver hysteresis.

Advanced features mentioned in related documentation include outstanding ESD robustness, eliminating the need for external ESD protection devices in typical applications. An internal Over-Voltage Protection (OVP) circuit protects the VBUS pin from voltages up to 30V. The USB334x family utilizes a reference clock from the Link, removing the cost of a dedicated crystal reference. It includes integrated 3.3V and 1.8V regulators, allowing operation from a single power supply. The USB334x is optimized for portable applications requiring low operating and standby currents, and supports the USB Link Power Management protocol (LPM) to further reduce USB operating currents. The family is enabled with SMSC's RapidCharge AnywhereTM, supporting USB-IF Battery Charging 1.2 for enhanced charging capabilities up to 1.5 Amps. It meets requirements for Hi-Speed USB Host, Device, or On-the-Go (OTG) transceivers and provides USB UART mode, with USB Audio mode available in versions with an integrated USB switch. The USB334x uses the industry-standard UTMI+ Low Pin Interface (ULPI) with a 'wrapper-less' technology for low latency transmit and receive times.
