The DLIN, DCD’s IP Core for Local Interconnect Network, is an ideal solution most of all for automotive designs. As technologies and facilities implemented in a car grow every year, the need for a cheap serial network has arisen. That’s why LIN seems to be the most suitable solution to integrate intelligent sensor devices or actuators in today’s cars. Contrary to the CAN, it enables cost competitive serial communication, building the same an extended vehicle’s electrical network, which… will be used as CAN’s sub-network. – Our DLIN controller supports transmission speed between 1 and 20kb/s – says Jacek Hanke, CEO in Digital Core Design – that allows to transmit and receive LIN messages compatible to LIN 1.3, LIN 2.1 and also the newest LIN 2.2 rev A.

That’s why the DLIN is ideal for communication in intelligent sensors and actuators, where the bandwidth and versatility of CAN is not required. DCD’s IP Core provides an interface between a microproces-sor/microcontroller and a LIN bus. It can work as a master or as a slave LIN node, depending on a working mode determined by the microprocessor/microcontroller. The reported information status includes the type and condition of transfer operations being performed by the DLIN, as well as a wide range of LIN error conditions (overrun, framing, parity, timeout). DCD’s IP Core includes also a programmable timer, which allows to detect timeout and synchronization error. The Core is described at RTL level, empowering the target use in FPGA and ASIC technologies.
