General description
The P82C150 is a single-chip 16-bit I/O device including a Controller Area Network (CAN) protocol controller with automatic bit rate detection and calibration. It features 16 configurable I/O port pins with programmable direction, digital and analog modes.
The P82C150 provides a configurable event capture facility supporting automatic transmission caused by a change on the port input pins.
The clock oscillator requires no external components, thus, the cost of the CAN link is reduced significantly.
The P82C150 is a very cost-effective way to increase the I/O capability of a microcontroller based CAN node as well as to reduce the amount and complexity of wiring. Advanced safety is provided by the CAN protocol.
