The SJA1124 is a quad Local Interconnect Network (LIN) channel device. Each of the four channels contains a LIN leader controller and LIN transceiver with leader termination. LIN leader frames are transferred to the physical LIN bus via the LIN
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
