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.
