CP3BT26 Reprogrammable Connectivity Processor with Bluetooth^®, USB, and CAN
Interfaces
Check for Samples: CP3BT26
1 GENERAL DESCRIPTION
The CP3BT26 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, Universal Serial Bus (USB)
1.1 node, CAN, 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
CP3BT26 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 TI’s LMX5252,
the CP3BT26 provides a complete Bluetooth system solution.
Texas Instruments offers a complete and industry-proven application development environment for
CP3BT26 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active
Emulator, Bluetooth Development Board, Bluetooth Protocol Stack, and Application Software.
