The SJA1124 is a quad Local Interconnect Network (LIN) master channel device. Each of the four channels contains a LIN master controller and LIN transceiver with master termination. LIN master 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. Transmit data streams received on the SPI are converted by the SJA1124 into LIN master frames transmitted on the LIN bus. The LIN master frames are transmitted as optimized bus signals shaped to minimize ElectroMagnetic Emission (EME). The LIN bus output pins are pulled HIGH via internal LIN master termination resistors. Data streams received on the LIN bus input pins can be read by the microcontroller via the SPI. Power consumption is very low in Low Power mode. However, the SJA1124 can still be woken up via the LIN pins and the SPI interface.
