MCP2544WFDT-E/MF

Drivers, Receivers, Transceivers Overview

The MCP2544WFDT-E/MF is a CAN FD transceiver from Microchip Technology, designed for high-speed communication up to 8 Mbps. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. The device features Wake-up on Pattern (WUP) functionality compliant with ISO 11898-2:2016, ensuring efficient power management in standby mode. It includes internal protection against ground faults and thermal shutdown, along with ESD protection meeting IEC61000-4-2 standards up to ±13 kV.

Drivers, Receivers, Transceivers Feature Summary

• Supports CAN 2.0 and CAN FD physical layer requirements with optimized performance at 2, 5, and 8 Mbps data rates.
• Enables remote wake-up via dedicated Wake-up Pattern (WUP) signals as specified in ISO 11898-2:2016.
• Provides robust internal protection including automatic thermal shutdown and permanent dominant detection on TXD and the bus.
• Ensures bus isolation by disconnecting CANH and CANL pins when the device is unpowered or during brown-out events.

Drivers, Receivers, Transceivers Applications

• Automotive networks requiring CAN FD support
• Industrial control systems
• Aerospace and defense applications
• Medical equipment interfaces
• Consumer electronics with CAN connectivity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) rather than High grade variants. Confirm the 'MF' package designation matches the required 3x3 DFN footprint with exposed thermal pad. Ensure compatibility with system voltage levels, noting that digital I/O is internally tied to VDD for this model variant.

Drivers, Receivers, Transceivers Selection Notes

Select this component when Wake-up on Pattern (WUP) is required for low-power standby modes in CAN FD networks. Choose the MCP2544WFDT over the MCP2542WFDT if an external VIO pin is not needed, as the digital I/O supply is internally connected to VDD. Consider the 3x3 DFN package for space-constrained PCB layouts requiring enhanced thermal dissipation through the exposed pad.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2542FD/4FD and MCP2542WFD/4WFD family of CAN FD transceivers. The MCP2544WFDT variant specifically integrates an internal level shifter for digital I/O pins and supports WUP functionality. It shares core electrical characteristics with the MCP2542WFDT but differs in pin configuration and I/O supply architecture.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MCP2542WFDT-E/MF for variants requiring an external VIO pin. Ensure replacement parts maintain the same WUP capability and temperature grade if environmental constraints are critical.
