MCHPMCP2542WFD-E/SN
Overview
The MCP2542WFD-E/SN is a high-speed CAN FD transceiver designed for reliable communication between a CAN controller and the physical bus. It supports data rates up to 8Mbps and features an integrated Vio pin for direct interfacing with microcontrollers operating from 1.8V to 5V. This AEC-Q100 qualified device is optimized for automotive and industrial environments requiring low quiescent current and robust ESD protection.
Why Choose This Part
The device offers a very low standby current of 4uA and a wide Vio range that eliminates the need for external level shifters when using low-voltage MCUs. It includes advanced safety features like Wake-up on Pattern (WUP), automatic thermal shutdown, and ground fault detection. The CAN bus pins are specifically designed to be disconnected when the device is unpowered, preventing bus loading issues.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, use the MCP2542WFDT-E/SN in conjunction with a CAN FD controller like the MCP2517FD or an integrated MCU. Ensure a 4.5V to 5.5V Vdd supply is provided for the transceiver core and match the Vio pin to your microcontroller's I/O voltage. Place a 100nF bypass capacitor close to the Vdd pin and follow standard CAN bus termination practices with 120-ohm resistors.
