CP3BT26 Reprogrammable Connectivity Processor with

Bluetooth

1.0

The CP3BT26 connectivity processor combines high perfor-

mance with the massive integration needed for embedded

Bluetooth applications. A powerful RISC core with on-chip

SRAM and Flash memory provides high computing band-

width, hardware communications peripherals provide high-

I/O bandwidth, and an external bus provides system ex-

pandability.

On-chip communications peripherals include: Bluetooth

Lower Link Controller, 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). Addi-

tional on-chip peripherals include Random Number Gener-

ator (RNG), DMA controller, CVSD/PCM conversion

module, Timing and Watchdog Unit, Versatile Timer Unit,

Multi-Function Timer, and Multi-Input Wake-Up (MIWU)

unit.

Bluetooth 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 gen-

eration of embedded Bluetooth products, the CP3BT26 is

backed up by the software resources designers need for

rapid time-to-market, including an operating system, Blue-

tooth protocol stack implementation, peripheral drivers, ref-

environment. Combined with a Bluetooth radio transceiver

such as National’s LMX5252, the CP3BT26 provides a com-

plete Bluetooth system solution.

National Semiconductor offers a complete and industry-

proven application development environment for CP3BT26

applications, including the IAR Embedded Workbench,

iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth

Development Board, Bluetooth Protocol Stack, and Applica-

tion Software.
