A powerful RISC core with 4Kbyte instruction cache and a Teak® DSP coprocessor provides high computing bandwidth, DMA-driven hardware communications peripherals provide high I/O bandwidth, and an external bus provides system expandability.
On-chip communications peripherals CP3SP33 include: Bluetooth Lower Link Controller, Universal Serial Bus (2.0) OTG node and host controller, dual CAN, dual Microwire/Plus/SPI, dual ACCESS.bus, quad UART, 10-bit A/D converter, and telematics/audio codec. Additional on-chip peripherals include DMA controller, dual CVSD/PCM conversion module, I2S and AAI digital audio bus interfaces, Timing and Watchdog Unit, dual Versatile Timer Unit, dual Multi-Function Timer, and Multi-Input Wake-Up (MIWU) unit.
In addition to providing the features needed for the next generation of embedded Bluetooth products, the CP3SP33 is backed up by the software resources that 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 an external program memory and a Bluetooth radio transceiver such as National's LMX5252, the CP3SP33 provides a complete Bluetooth system solution.
National Semiconductor offers a complete and industryproven application development environment for CP3SP33 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active Emulator, Bluetooth Development Board, Bluetooth protocol stack, and application examples.
