Overview
The SJA1000T/N1,118 is a stand-alone Controller Area Network (CAN) controller produced by NXP USA Inc. It is designed for use in automotive and general industrial environments, serving as a successor to the PCA82C200 CAN controller from Philips Semiconductors. The SJA1000T supports both the BasicCAN mode and the PeliCAN mode, which extends the functionality to comply with the CAN 2.0B protocol specification.
