描述 Description

The SJA1000 is a stand-alone controller for the Controller Area Network (CAN) used within automotive and general industrial environments. It is the successor of the PCA82C200 CAN controller (BasicCAN) from Philips Semiconductors. Additionally, a new mode of operation is implemented (PeliCAN) which supports the CAN 2.0B protocol specification with several new features.

特性 Features

? Pin compatibility to the PCA82C200 stand-alone CAN controller
