Description The CP3BT13 connectivity processor combines high performance
with the massive integration needed for embedded
Bluetooth applications. A powerful RISC core with on-chip
SRAM and Flash memory provides high computing bandwidth,
communications peripherals provide high I/O bandwidth,
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 generation
of embedded Bluetooth products, the CP3BT13 is
backed up by the software resources designers need for
rapid time-to-market, including an operating system, rapid time-to-market, including an operating system, Bluetooth protocol stack implementation, reference designs, and and an
integrated development environment. Combined with National's LMX5252 Bluetooth radio transceiver, theCP3BT13 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, Development Board, iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth Development Board, Bluetooth Protocol Stack, and Application
Software.
