CP3BT26 Reprogrammable Connectivity Processor with  
Bluetooth®, USB, and CAN Interfaces  
1.0 General Description  
The CP3BT26 connectivity processor combines high perfor- advanced power-saving modes achieve new design points  
mance with the massive integration needed for embedded in the trade-off between battery size and operating time for  
Bluetooth applications. A powerful RISC core with on-chip handheld and portable applications.  
SRAM and Flash memory provides high computing band-  
In addition to providing the features needed for the next gen-  
width, hardware communications peripherals provide high-  
eration of embedded Bluetooth products, the CP3BT26 is  
I/O bandwidth, and an external bus provides system ex-  
backed up by the software resources designers need for  
pandability.

On-chip communications peripherals include: Bluetooth tooth protocol stack implementation, peripheral drivers, ref-  
Lower Link Controller, Universal Serial Bus (USB) 1.1 node, erence designs, and an integrated development  
CAN, Microwire/Plus, SPI, ACCESS.bus, quad UART, 12-bit environment. Combined with a Bluetooth radio transceiver  
A/D converter, and Advanced Audio Interface (AAI). Addi- such as National’s LMX5252, the CP3BT26 provides a com-  
tional on-chip peripherals include Random Number Gener- plete Bluetooth system solution.
