LIN Features
UART Features
The LIN (Local Interconnect Network) is a serial communications protocol which efficiently sup-
ports the control of mechatronics nodes in distributed automotive applications. The main
properties of the LIN bus are:
•
•
•
•
•
•
LIN provides a cost efficient bus communication where the bandwidth and versatility of CAN are
not required. The specification of the line driver/receiver needs to match the ISO9141 NRZ-
standard.
If LIN is not required, the controller alternatively can be programmed as Universal Asynchronous
serial Receiver and Transmitter (UART).
