Complete Solutions and Design Flexibility Address Telematics, Information and Entertainment Applications in Cars
May 25, 2004 - National Semiconductor Corporation announced four next-generation connectivity processors that provide an easy, cost-effective way to connect different types of devices in automobiles via wide-area, local-area or personal-area networks.National's new connectivity processors integrate Bluetooth® wireless technology, controller area network (CAN) and universal serial bus (USB) interfaces with additional software to accelerate development of telematics applications such as handsfree communication devices and information and entertainment devices such as off-board automotive GPS navigation systems. The connectivity processors also can be used in consumer, medical and industrial applications such as remote sensors or personal health data loggers.
These processors expand National's CP3000 family of connectivity processors, which dramatically simplify the creation of linked networks and connected devices. For wireless applications, the CP3000 processors include a fully embedded Bluetooth interface with baseband processing, a host protocol stack and dedicated profiles. Like other members of the CP3000 family, these new products include a complete package of hardware, software with Bluetooth profiles in pre-qualified source code, development tools and worldwide technical support. Additional features of these new processors include a high-resolution, 12-bit analog-to-digital converter, additional serial interfaces and increased memory.
Features and Benefits
The CP3BT23, CP3BT26, CP3UB26 and CP3CN23 connectivity processors feature National's power-efficient CompactRISCTM 16-bit microcontroller core and a wealth of on-chip peripherals. Each processor features 256 kilobytes of on-chip Flash, 32 kilobytes of on-chip static RAM, an additional 8 kilobytes of on-chip data Flash and the ability to address up to 12 megabytes of external memory. Additional functions and interfaces include versatile timer units; multifunction timers; audio interfaces; USART, UART, Microwire and SPI interfaces; ACCESS.bus, which is I2C compatible; programmable I/O ports; an on-chip clock; a phased-lock loop; and a watchdog timer. The processors run from 0 to 24 MHz and are available in an extended temperature range of -40 to +85 degrees Celsius.
