CAN transceiverMicrochip Technology Inc. announced a family of High-Speed (HS) CAN transceivers, the MCP2561/2. These new devices serve as an interface between a CAN protocol controller and the physical two-wire CAN bus. The new family of transceivers meet CAN specification requirement “GIFT ICT Group Conformance Test Specification V1.0”. The new family of MCP2561/2 transceivers provides two device options. The MCP2561 is an HS CAN transceiver in an 8-pin package and features a SPLIT pin.  The SPLIT pin helps to stabilize common mode in biased split termination schemes.  The MCP2562 is also an HS CAN transceiver available in an 8-pin package and features a Vio pin.  The Vio pin can be tied to a secondary supply in order to internally level shift the CAN transceiver digital I/Os for easy microcontroller interfacing. This is beneficial when a system is using a microcontroller 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 decreasing system costs and complexities. The transceivers have very low standby current consumption (<5  µA typical) helping meet automotive Electronic Control Unit (ECU) low-power budget requirements. Both parts are also available in 8-lead PDIP, SOIC and 3x3 mm DFN (leadless) package types allowing for development flexibility and offering alternatives for space limited application boards. The MCP2561/2 CAN transceivers are well suited for a wide range of 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.
