Special CAN and LIN chips being developed for automotive networks

27 August 2003 News

Royal Philips Electronics has announced the first silicon of its system basis chip (SBC) family, expanding its portfolio of in-vehicle networking (IVN) products. Philips' SBCs combine transceiver functionality, voltage regulators and a watchdog, with diagnostics and an embedded fail-safe system.

This one-chip integration of generic electronic control unit (ECU) functions with a powerful fail-safe system makes it easier for design engineers to build reliable automotive network nodes.

Philips is recognising a trend toward more complex networks in vehicles. "As the industry moves toward more complex in-vehicle networks there will be an increased need for integration to keep system reliability high," said Jacob van der Pol, CAN/LIN segment manager for Philips automotive marketing and sales. "We have developed the Philips SBC concept in cooperation with leading car manufacturers to ensure that we are meeting the industry's requirements for this growing market. Our control area network (CAN)- local interconnect network (LIN) system basis chips are the direct result of this cooperation."

Philips says that the SBC family will cover all CAN and LIN network applications, ranging from local electric window nodes to central engine management and dashboard applications. The SBC family offers the choice between one or two physical layers, always in combination with the same system core, generic functions and fail-safe system, and always in the same small package. This makes it easy and cost-effective for designers to substitute physical layers in electronic control units (ECUs), with maximum re-use of ECU hardware and software.

The first two products in the SBC family are the UJA1061, which combines fault-tolerant CAN with LIN, and the UJA1065, which combines high-speed CAN with LIN.
