AN91014: Application of the P8xC592 microcontroller with CAN interface |
|
The integrated circuit P8xC592 from Philips is a single-chip high performance microcontroller designed for use in automotive and general industrial applications. It is a high-end derivative of the 80C51 family CMOS microcontrollers.
In addition to the 80C51 standard features the P8xC592 provides a number of dedicated hardware features for sophisticated control applications. It includes timers, A/D converter, PWM output, UART and a CAN protocol controller (CAN = Controller Area Network) for serial communication. The P8xC592 covers the complete CAN specification, offering important features such as multi-master serial communication capability with a high number of participating network nodes, programmable data transmission rate up to 1 Mbit/s and powerful error handling.
This technical publication puts special emphasis on CAN applications of the P8xC592. The application note provides a simple circuit example for a CAN module built with a P8xC592. Furthermore flowcharts are discussed to let the reader become familiar with the software aspects of CAN communication. A practical example shows that there is very little CPU load for the control of CAN communication.
