Low-power high-speed CAN transceivers

Microchip Technology (USA) has introduced the MCP2561/2 CAN transceivers compliant to ISO 11898-5. They serve as an interface between a CAN protocol controller and the physical two-wire CAN network.

THE SERIES OF TRANSCEIVERS COME IN AN 8-pin SOIC or 8-pin PDIP or 8-pin DFN (3 mm x 3 mm) package. The MCP2561 features a Split pin, which helps to stabilize common mode in biased split termination schemes. The MCP2562 provides a Vio pin, which can be tied to a secondary supply in order to internally level shift the CAN transceiver digital I/Os for micro-controller interfacing. This is beneficial when a system is using a micro-controller at a VDD less than 5 V (for example, 1,8 V or 3,3 V) and eliminates the need for an external level translator. The transceivers have an industry standby current consumption (less than 5 µA typical). Additionally, the components support both Extended (E): -40 °C to +125 °C and High (H): -40 °C to +150 °C temperature ranges providing customers the ability to use one part across various CAN connected applications. The transceivers are suited for applications in the automotive market including power train, body and convenience, diagnostics, safety and security and the industrial market, including manufacturing, construction and agriculture, among others.

These transceivers meet CAN specification requirement "GIFT ICT Group Conformance Test Specification V1.0" as verified by C&S Group in addition to other global automotive Electromagnetic Compatibility (EMC) requirements such as "Hardware Requirements for LIN, CAN and Flexray Interfaces in Automotive Applications," Version 1.3, May 2012 as verified by IBEE.
