DLIN

DCD-SEMI believes that even though something may be small or slow, it can still offer maximal efficiency and ultimate reliability. That’s why our DLIN controller supports transmission speed between 1kb/s and 20kb/s, which allows to transmit and receive LIN messages compatible to:

• LIN 1.3,
• LIN 2.1
• and the newest LIN 2.2A

DLIN bridge to APB, AHB, AXI bus, it is a soft core of the Local Interconnect Network (LIN). This interface is a serial communication protocol, primarily designed to be used in automotive applications. Compared to the CAN, The LIN is slower, but thanks to its simplicity, it is much more cost effective. Our Core is ideal for communication in intelligent sensors and actuators, where the bandwidth and versatility of the CAN is not required. The DLIN core provides an interface between a microprocessor/microcontroller and LIN bus. It can work as a master or slave LIN node, depending on a work mode determined by the microprocessor/microcontroller. DCD’s controller supports transmission speed between 1 and 20kb/s, which allows it to transmit and receive LIN messages compatible to LIN 1.3., LIN 2.1, and the newest 2.2A specification. The reported information status includes type and condition of transfer operations performed by the DLIN, as well as a wide range of LIN error conditions (overrun, framing, parity, timeout). Our Core includes programmable timer which allows detecting timeout and synchronization error. The DLIN is described at RTL level, empowering the target use in FPGA and ASIC technologies.
