Part Number : CUSB
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 EZ-USBTM FX chip.
Features : - Serial Interface Engine
- support full speed devices
- extraction clock and data signals in internal DPLL
- NRZI decoding/encoding
- bit stuffing/stripping
- CRC checking/generation
- interface for an external transceiver
- up to 31 configurable endpoints
- support control transfers by endpoint 0
- support bulk, interrupt and isochronous transfers
- double buffering for isochronous endpoints
- programmable double buffering for bulk and interrupt endpoints
- automatic data retry mechanism
- data toggle synchronization mechanism
- auspend and resume power management functions
- remote Wake-Up function
- endpoint buffers RAM interface
- 2x1024Bytes FIFO size for isochronous endpoints
- up to 64Bytes buffer size for each bulk, interrupt and control endpoints
- microcontroller interface
- asynchronous address and data bus interfaces, and read and write control signals (Internally synchronized within the CUSB core)
- interrupt request signals for application microcontroller
- interrupt vector for autovector interrupts
