1 / 200 page  ©2003 National Semiconductor Corporation www.national.com PRELIMINARY Sept. 2003 CP3UB17 Reprogrammable Connectivity Processor with USB Interface 1.0 General Description The CP3UB17 connectivity processor combines a powerful RISC core with on-chip SRAM and Flash memory for high computing bandwidth, hardware communications peripher- als for high I/O bandwidth, and an external bus for system expandability. On-chip communications peripherals include: USB control- ler, ACCESS.bus, Microwire/Plus, SPI, UART, and Ad- vanced Audio Interface (AAI). Additional on-chip peripherals include DMA controller, PCM/CSVD conversion module, Timing and Watchdog Unit, Versatile Timer Unit, Multi- Function Timer, and Multi-Input Wakeup. The CP3UB17 is backed up by the software resources de- signers need for rapid time-to-market, including an operat- ing system, peripheral drivers, reference designs, and an integrated development environment. National Semiconductor offers a complete and industry- proven application development environment for CP3UB17 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active Emulator, Develop- ment Board, and Application Software.
