The CUSB-DMA is an USB Function Controller, its
logic provides USB full speed function interface that meets the 1.1 revision of the USB specification. The CUSB-DMA logic handles bytes transfer autonomously and bridges USB interface to a simple read/write parallel interface. The can be customized and optimized for a specific application. It contains a set of Special Function Registers that is similar to the Cypress EZ-USB FX chip. The CUSB-DMA is developed for reuse in ASIC and FPGA
implementations. The design is strictly synchronous with positive-edge clocking, a synchronous reset and no internal tri-states; therefore scan insertion is straightforward...view full
Overview
The CUSB is an USB Function
Controller, its logic provides USB full speed function interface that meets the 1.1 revision of the USB specification. The CUSB logic handles bytes transfer autonomously and bridges USB interface to a simple read/write parallel interface. The CUSB can be customized and optimized for a specific application. It contains a set of Special Function Registers that is similar to the Cypress EZUSBTM FX chip.
The CUSB is developed for reuse in ASIC and FPGA implementations. The design is strictly synchronous with positive-edge clocking, a synchronous reset and no internal tri-states; therefore scan insertion is straightforward....view full
The CUSB2 logic provides USB High-speed/Full-speed
(480/12 Mbps) function interface that meets the 2.0 revision of the USB specification.
A variety of available interfaces for both PHY and CPU facilitates the controllers implementation in different development environments. Both FIFO interface and DMA controller speed up overall system performance. An off-the-shelf USB High Speed Development Platform integrates all hardware and software elements necessary for a successful System-on-Chip design.
The CUSB2 is a design developed for reuse in ASIC and FPGA implementations. The design is strictly synchronous with positive-edge clocking, synchronous reset and no internal tri-states; therefore scan insertion is straightforward...view full
