CP3UB17 Reprogrammable Connectivity Processor

with USB Interface

1.0

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, CVSD/PCM conversion module,

Timing and Watchdog Unit, Versatile Timer Unit, Multi-

Function Timer, and Multi-Input Wakeup.
