1 / 268 page  ©2004 National Semiconductor Corporation www.national.com FINAL JULY 2004 CP3UB26 Reprogrammable Connectivity Processor with USB and CAN Interfaces 1.0 General Description The CP3UB26 connectivity processor combines high per- formance with the massive integration needed for embed- ded applications. A powerful RISC core with on-chip SRAM and Flash memory provides high computing bandwidth, hardware communications peripherals provide high-I/O bandwidth, and an external bus provides system expand- ability. On-chip communications peripherals include: Universal Se- rial Bus (USB) 1.1 node, CAN, Microwire/Plus, SPI, AC- CESS.bus, quad UART, 12-bit A/D converter, and Advanced Audio Interface (AAI). Additional on-chip peripherals include Random Number Generator (RNG), DMA controller, CVSD/ PCM conversion module, Timing and Watchdog Unit, Ver- satile Timer Unit, Multi-Function Timer, and Multi-Input Wake-Up (MIWU) unit. Hand-held devices can be both smaller and lower in cost for maximum consumer appeal. The low voltage and advanced power-saving modes achieve new design points in the trade-off between battery size and operating time for hand- held and portable applications. In addition to providing the features needed for the next gen- eration of embedded products, the CP3UB26 is backed up by the software resources designers need for rapid time-to- market, including an operating system, peripheral drivers, reference designs, and an integrated development environ- ment. National Semiconductor offers a complete and industry- proven application development environment for CP3UB26 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active Emulator, Develop- ment Board, and Application Software.
