CP3UB26 Reprogrammable Connectivity Processor with USB Interface
1 GENERAL DESCRIPTION
The CP3UB26 connectivity processor combines high performance with the massive integration needed for
embedded 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 expandability.
On-chip communications peripherals include: Universal Serial Bus (USB) 1.1 node, CAN, Microwire/Plus,
SPI, ACCESS. 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, Versatile 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 handheld and portable applications.
In addition to providing the features needed for the next generation 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 environment.
Texas Instruments Incorporated offers a complete and industry-proven application development
environment for CP3UB26 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and
iC3000 Active Emulator, Development Board, and Application Software.
