MCP2544WFD-H/SN

Drivers, Receivers, Transceivers Overview

The MCP2544WFD-H/SN is a CAN FD transceiver in the MCP2542/4FD family, designed for high-speed communication up to 8 Mbps. It operates within a VDD supply range of 4.5V to 5.5V and supports an ambient temperature range from -40°C to +150°C (High grade). The device features Wake-up on Pattern (WUP) functionality compliant with ISO 11898-2:2016. It utilizes an 8-Lead SOIC package and includes internal protection against thermal shutdown and permanent dominant conditions.

Drivers, Receivers, Transceivers Feature Summary

• Supports CAN 2.0 and CAN FD physical layer requirements with optimized loop delay symmetry for data rates up to 8 Mbps.
• Enables remote wake-up via dedicated Wake-up Pattern (WUP) detection specified in ISO 11898-2:2016.
• Provides bus isolation by disconnecting CANH and CANL pins when the device is unpowered or during brown-out events.
• Includes automatic thermal shutdown protection and detection of permanent dominant conditions on TXD and the bus.

Drivers, Receivers, Transceivers Applications

• Automotive CAN 2.0 and CAN FD networks
• Industrial control systems requiring high-speed communication
• Aerospace and defense applications
• Medical equipment interfaces
• Consumer electronics with CAN connectivity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-Lead SOIC package configuration as documented in the product identification system. Confirm that the 'H' designation aligns with the required high-temperature operating range of +150°C for your application environment. Ensure compatibility with the WUP wake-up method if utilizing standby modes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a CAN FD transceiver with Wake-up on Pattern (WUP) capability is required for automotive or industrial designs. Choose the High (H) temperature grade variant if operation above +125°C is necessary. Note that unlike the MCP2542 series, this model lacks a separate VIO pin, as digital I/O supplies are internally connected to VDD.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2542FD/4FD and MCP2542WFD/4WFD family manufactured by Microchip Technology. The family differentiates models based on wake-up methods (Basic vs. WUP) and digital I/O supply configurations (Separate VIO vs. Internal connection to VDD). The MCP2544 variants specifically feature internal level shifters for digital I/O pins.
