CAN transceivers with flexible speeds

29 April 2015 Telecoms, Datacoms, Wireless, IoT

Microchip announced a new family of CAN FD (Controller Area Network Flexible Data-rate) transceivers – the MCP2561/2FD. As an interface between a CAN protocol controller and the physical two-wire CAN bus, these transceivers can serve both the CAN and CAN FD protocols. This product family not only helps automotive and industrial manufacturers with today’s CAN communication needs, but also provides a path for the newer CAN FD networks that are increasingly in demand.

These new devices have one of the industry’s lowest standby current consumption (less than 5 μA typical), helping to meet ECU low-power budget requirements. In addition, they support operation in the -40°C to 150°C temperature range, enabling usage in harsh environments.

The product family is available in 8-pin PDIP, SOIC and 3 x 3 mm DFN (leadless) packages. The MCP2561FD comes in an 8-pin package and features a SPLIT pin which helps to stabilise the common mode in biased split-termination schemes.

The MCP2562FD is available in an 8-pin package and features a Vio pin which can be tied to a secondary supply in order to internally level-shift the 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.
