SJA1000T/N1,118
Overview
The SJA1000T/N1,118 is a stand-alone CAN controller designed for automotive and industrial applications. It serves as the successor to the PCA82C200, maintaining hardware and software compatibility while adding the PeliCAN mode to support the full CAN 2.0B specification. This device manages the physical layer signaling and protocol framing via a parallel interface, offloading these tasks from a host microcontroller.
Why Choose This Part
This controller supports both BasicCAN and PeliCAN modes, offering flexibility for simple or complex network requirements. Its wide operating temperature range of -40degC to 125degC and 5V logic compatibility make it a reliable choice for harsh environments. The parallel interface is particularly advantageous for high-speed data transfer in systems using older 8-bit or 16-bit microcontrollers.
Applications
Key Specifications
Getting Started
To integrate this part, connect the parallel multiplexed address/data bus to your MCU and configure the clocking via an external crystal. Engineers typically use the NXP application notes for register-level configuration of the acceptance filters and bit timing. Ensure a proper CAN transceiver, such as a TJA1050, is used to interface between the SJA1000 and the physical differential bus.
