MCP2542FD-E/MF

Drivers, Receivers, Transceivers Overview

The MCP2542FD-E/MF is a CAN FD transceiver from the MCP2542 family, designed for high-speed communication up to 8 Mbps. It supports CAN 2.0 and CAN FD physical layer requirements with a maximum propagation delay of 120 ns and loop delay symmetry of -10%/+10% at 2 Mbps. The device features wake-up on CAN activity with a 3.6 µs filter time and includes a VIO pin for direct interface with microcontrollers operating between 1.8V and 5V. It operates within an extended temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MF against official Microchip documentation to confirm package type and tape/reel specifications. Ensure the E suffix corresponds to the required extended temperature range (-40°C to +125°C) for your application environment. Cross-reference the datasheet revision DS20005514C for any updates to electrical characteristics or pin configurations before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when basic wake-up functionality is sufficient, as opposed to pattern-based wake-up found in WFD variants. The presence of the VIO pin allows independent power supply for digital I/O, facilitating integration with 1.8V to 5V logic controllers. Ensure the system design accommodates the 4.5V to 5.5V VDD supply requirement and utilizes the exposed thermal pad for optimal heat dissipation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2542FD/4FD and MCP2542WFD/4WFD family, which implements ISO 11898-2:2016 standards. The MCP2542FD variant specifically distinguishes itself by offering wake-up on CAN activity rather than Wake-up on Pattern (WUP). It is qualified according to AEC-Q100 Rev. G for Grade 0 temperature ranges, ensuring reliability in demanding environments.

Drivers, Receivers, Transceivers Replacement Considerations

MCP2542FD-E/SN offers the same functionality in an SOIC-8 package. MCP2542WFDT-E/MNY provides Wake-up on Pattern (WUP) capability instead of basic wake-up.
