CP3BT23 Reprogrammable Connectivity Processor with Bluetooth and Dual CAN
Interfaces
Check for Samples: CP3BT23
1 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 highI/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 Texas
Instruments’ LMX5252, the CP3BT23 provides a complete Bluetooth system solution.
Texas Instruments offers a complete and industry-proven 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.
