Part Number : LIN
Short Desc. : LIN Bus Master/Slave Controller Core
Overview :

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 core can optionally be modified to implement a standalone slave controller that requires no assistance from a host processor to transmit response frames.

The LIN core is a microcode-free design developed for reuse in ASIC and FPGA im-plementations. 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.


Features : - Support of LIN specification 2.0, 2.1, and 2.2A
- 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)
- 8-byte data buffer
- 8-bit host controller interface
- Wrappers for 32bit busses (e.g. APB) can be made available upon request
- Slave can be implemented with or without clock synchronization
- Optional acceptance filter enable slave core to transmit response frames without host assistance
- Fully synchronous design, available in VHDL or Verilog, completely synthesizable
- The LIN Controller synthesizes to approximate 2500 to 3800 gates depending on the configuration
- Robustly verified and multiple times production proven IP core
