The LIN core is a communication controller that transmits and receives complete LIN frames to perform serial communication according to the LIN Protocol Specification. The LIN controller can be implemented as a master or as a slave and operate on LIN 1.3, 2.0, 2.1 or 2.2 LIN network. It uses a single master/multiple slave concept for message transfer between nodes of the LIN network. The message transfer can be controlled via a micro controller interface and a LIN transceiver is needed for the connection to the LIN bus. The LIN core is a microcode-free design developed for reuse. The scan-ready design is strictly synchronous with positive-edge clocking and no internal tri-states. The robustly verified core has been production proven multiple times.


  • Supports of LIN specification 2.0, 2.1, and 2.2A, and is backwards compatible with LIN specification 1.3
  • Configurable for support of master or slave functionality
  • Programmable data rate between 1 Kbit/s and 20 Kbit/s (for master)
  • Automatic bit rate detection (for slave)
  • Production proven multiple times

Device Utilization and Performance

The core synthesizes to about 700 LEs.
