LIN Transceiver

11.2.8

Slope Selection

The LIN transceiver offers a LIN Low-Slope Mode for 10.4 kBaud communication and a LIN Normal-Slope Mode

for 20 kBaud communication. The only difference is the behavior of the transmitter. In LIN Low-Slope Mode, the

transmitter uses a lower slew rate to further reduce the EME compared to Normal-Slope Mode. This complies with

SAE J2602 requirements.By default, the device works in LIN Normal-Slope Mode. The selection of LIN Low-Slope

Mode is done by an SPI bit LIN_LSM and will become effective as soon as CSN goes ‘HIGH’. Only the LIN Slope

is changed. The selection is accessible in SBC Normal Mode only.

11.2.9

Flash Programming via LIN

The device allows LIN flash programming, e.g. of another LIN Slave with a communication of up to 115 kBaud.

This feature is enabled by de-activating the slope control mechanism via a SPI command (bit LIN_FLASH) and

will become effective as soon as CSN goes ‘HIGH’. The SPI bit can be set in SBC Normal Mode.

Note: It is recommended to perform flash programming only at nominal supply voltage VSHS = 13.5V to ensure

stable data communication.
