CP3BT10 Reprogrammable Connectivity Processor
with Bluetooth^® and USB Interfaces
1.0 General Description
The CP3BT10 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, USB, ACCESS.bus, Microwire/SPI,
UART, and Advanced Audio Interface (AAI). Additional on-
chip peripherals include DMA controller, CVSD/PCM con-
version 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 CP3BT10 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
CP3BT10 provides a complete Bluetooth system solution.
National Semiconductor offers a complete and industry-
proven application development environment for CP3BT10
applications, including the IAR Embedded Workbench,
iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth
Development Board, Bluetooth Protocol Stack, and Applica-
tion Software.
