Philips Semiconductors has announced the launch of the XA-C3, a new member of the high-performance 16-bit XA microcontroller family, specifically for \"Controller Area Network (CAN)\" applications such as high-performance industrial and automotive systems. The XA-C3 microcontroller complies with the CAN 2.0B standard and includes Philips Semiconductor\'s market-proven PeliCAN (Philips Extended Library CAN) functionality and integrates a CAN transport layer protocol processor, resulting in higher performance and reduced system cost and design time. CAN components have extremely high communication reliability, making them an ideal solution for equipment control applications such as copiers, medical equipment and factory automation equipment. CAN microcontrollers can also be used in applications such as electric wheelchairs and navigation systems. According to the CAN Automation Organization (CiA), the number of CAN application nodes in 1998 was 60 million, and it is expected that this number will increase by nearly 50% in 1999 and more than 50% by the end of 2000. \"Philips Semiconductors is committed to providing highly integrated microcontroller solutions to meet the needs of the rapidly growing CAN market.\" XA-C3 Incorporating Philips Semiconductor\'s experience in the CAN transceiver and 16-bit microcontroller market, it can provide design engineers with a low-cost, high-performance CAN2.0B solution. \"XA-C3 is a member of Philips Semiconductor\'s Extended Architecture (XA) microcontroller family. It uses a PeliCAN CAN 2.0B engine to communicate with standard peripherals and can support a maximum CAN data transfer rate of 1Mbps. It has 32K one-time programmable (OTP) memory and 1K on-chip \"static random access memory (SRAM)\". The chip also contains a universal asynchronous receiver and transmitter (UART) and a serial peripheral interface (SPI) port to achieve the integration of various serial ports and CAN networks. The component supports CAN transport layer protocols such as DeviceNET, CANopen and OSEK in hardware, eliminating the need for engineers to implement these functions in software and thus reducing the burden on the central processing unit (CPU), thereby improving the running capabilities of such applications. Compared with traditional CAN microcontrollers, the CAN protocol processor of XA-C3 can reduce the 16-bit CPU in most cases. Core resources are used to run the application program. This is because the device uses 32 CAN transport layer message objects (which can be set for receiving or transmitting) and 32 independent filters/discriminators (each can represent a group address through 30-bit ID matching and full 29-bit masking). The device supports C language operation and runs at 32MHz operating frequency (4.5-5.5V). XA-C3 also supports multi-tasking and real-time operation with a 16-level interrupt priority system. Its interrupt system can handle 42 vector interrupts and can perform fast task switching. In addition, the device supports power saving and idle modes for low power operation.
