Smart SPI-LIN Quad LIN transceivers with LIN controllers integrated

The SJA1124 is a quad local interconnect network (LIN) commander channel device. Each of the four channels contains a LIN

commander controller and LIN transceiver with commander termination. LIN commander frames are transferred to the physical LIN bus via the LIN physical layer.

The SJA1124 is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016(12 V LIN)

and SAE J2602-1.

A serial peripheral interface (SPI) and an interrupt output provide the interface between the SJA1124 and a microcontroller.
