LIN Transceiver

Introduction
The LIN Module is a transceiver for the Local Interconnect Network (LIN) compliant to the LIN2.2 standard,
backward compatible to LIN1.3, LIN2.0 and LIN2.1. It operates as a bus driver between the protocol controller and
the physical network. The LIN bus is a single wire, bi-directional bus typically used for in-vehicle networks, using
baud rates between 2.4 kBaud and 20 kBaud. Additionally baud rates up to 115.2 kBaud are implemented.
The LIN Module offers several different operation modes, including a LIN Sleep Mode and the LIN Normal Mode.
The integrated slope control allows to use several data transmission rates with optimized EMC performance. For
data transfer at the end of line, a Flash Mode up to 115.2 kBaud is implemented. This Flash Mode can be used
for data transfer under special conditions for up to 250 kbit/s (in production environment, point-to-point
communication with reduced wire length and limited supply voltage).
