CP3BT23 Description

The CP3BT23 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, hardware communications peripherals provide high- I/O bandwidth, and an external bus provides system expandability.

On-chip communications peripherals include: Bluetooth Lower Link Controller, dual CAN controllers, 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.

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 CP3BT23 is backed up by the software resources designers need for rapid time-to-market, including an operating system, Bluetooth protocol stack implementation, peripheral drivers, reference designs, and an integrated development environment. Combined with a Bluetooth radio transceiver such as Nationalis LMX5252, the CP3BT23 provides a complete Bluetooth system solution.

National Semiconductor offers a complete and industryproven application development environment for CP3BT23 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth Development Board, Bluetooth Protocol Stack, and Application Software.
