Analog Solutions—Robust Reliable Performance MC33901 and MC34901 High-Speed CAN Physical Layer— Flexible Data Ready Industrial Applications (MC34901) •Transportation Heavy vehicles Agriculture machinery Aviation systems Off-road recreational equipment Trains Electric Vehicles •Backplanes •Lift/elevators • Factory automation Programmable logic control (PLC) Robotics • Industrial process control Power generation systems Automotive Applications (MC33901) • Supports automotive CAN high-speed applications and CAN FD 2M • Body electronics • Power train • Chassis and safety •Infotainment • Diagnostic equipment •Accessories Overview The MC33901 and MC34901 CAN high speed physical layers are Freescale’s latest standard cost effective products used to convert digital protocol information into analog CAN communication. They target CAN Flexible Data (FD) operation up to 2 Mbps. The MC34901 supports long-length CAN node interconnects for industrial applications while the MC33901 has a built-in transceiver dominant timeout feature for automotive applications. Freescale’s robust MC33901 and MC34901 CAN high-speed physical layers offer extremely low quiescent current while exceeding the most stringent EMC/ESD requirements without added circuitry. The MC33901 and MC34901 allow for the implementation of a cost-effective system. These parts minimize external circuitry and save system cost including the elimination of common mode choke and other components. It’s easy to get started with the with the KIT33901EPEVB and KIT34901EPEVB evaluation boards. These small evaluation boards can be used for quick application prototyping and demonstration of the MC33901 and MC34901 products respectively, for fast design and quick time to market.
