CP3BT13 Reprogrammable Connectivity Processor

with Bluetooth

1.0

The CP3BT13 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, communications peripherals provide high I/O band-

width, and an external bus provides system expandability.

On-chip communications peripherals include: Bluetooth

Lower Link Controller, CAN, ACCESS.bus, Microwire/Plus,

SPI, UART, and Advanced 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.

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 CP3BT13 is

backed up by the software resources designers need for

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

tooth protocol stack implementation, reference designs, and

an integrated development environment. Combined with

National’s LMX5252 Bluetooth radio transceiver, the

CP3BT13 provides a complete Bluetooth system solution.

National Semiconductor offers a complete and industry-

proven application development environment for CP3BT13

applications, including the IAR Embedded Workbench,

iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth

Development Board, Bluetooth Protocol Stack, and Applica-

tion Software.
