SMSC USB3500
SOC/FPGA/ASIC
Including Device Controller
USB App.
Hi-Speed
The USB3500 is a stand-alone Hi-Speed USB Physical Layer Transceiver (PHY). The USB3500 uses
a UTMI+ interface to connect to an SOC or FPGA or custom ASIC. The USB3500 provides a flexible
alternative to integrating the analog PHY block for new designs.
The USB3500 provides a fully compliant USB 2.0 interface, and supports High-Speed (HS), Full-Speed
(FS), and Low-Speed (LS) USB. The USB3500 supports all levels of the UTMI+ specification as shown
in
The USB3500 can also, as an option, fully support the On-the-Go (OTG) protocol defined in the On-
The-Go Supplement to the USB 2.0 Specification. On-the-Go allows the Link to dynamically configure
the USB3500 as host or peripheral configured dynamically by software. For example, a cell phone may
connect to a computer as a peripheral to exchange address information or connect to a printer as a
host to print pictures. Finally the OTG enabled device can connect to another OTG enabled device to
exchange information. All this is supported using a single low profile Mini-AB USB connector.
Designs not needing OTG can ignore the OTG feature set.
