Overview
Synopsys' DesignWare® USB 2.0 Device Controller (UDC20) supports high-speed, 480-Mbps transfers, performing 40 times faster than USB 1.1 full-speed operation.
Integrating this digital, synthesizable logic into an ASIC, FPGA, or ASSP peripheral design ensures complete USB 2.0 compliance, device functionality, and backward compatibility with USB 1.1.
Optimizing development time and diminishing engineering risk, Synopsys' UDC20 helps designers bring their peripheral design to market faster.
The UDC20 features industry-standard interfaces that easily integrate the USB 2.0 transceiver and application logic.
The USB 2.0 Transceiver Macrocell Interface (UTMI) connects the UDC20 to an external stand-alone or integrated macrocell USB 2.0 transceiver.
Synopsys' Virtual Component Interface (VCI) provides seamless integration with any application logic or system bus.
For fast configuration and optimization, Synopsys' RapidScript® utility builds the core and test environment in source code for the targeted application.
