The SMSC USB3300 is a high-performance USB host or device PHY with ULPI Low Pin Interface. It meets USB-IF“Hi-Speed” certification and the Universal Serial Bus Specification Rev 2.0 requirements, and is compliant with the ULPI Specification revision 1.1 in 8-bit mode.
The SMSC USB3300 is a highly integrated USB PHY designed to support Hi-Speed USB 2.0 connections while minimizing board space and interface pins. It features an industry-standard UTMI+ Low Pin Interface (ULPI), which reduces the standard 54-pin UTMI+ interface down to just 12 pins using in-band signaling.
The device operates as a Hi-Speed or Full-Speed USB Host, Device, or On-The-Go (OTG) peripheral. It includes an internal 24MHz crystal oscillator and PLL for 480MHz operation, along with integrated pull-up resistors and short-circuit protection to ensure reliable startup and robust performance.
The device is available in a 32 pin QFN package that measures 5 x 5 x 0.9mm.
The device draws 54.7mA when unconfigured, which is ideal for bus powered applications.
The suspend current is 83uA (typical), making it suitable for battery powered applications.
