MCHPMCP2542FDT-E/MNY

Overview

The MCP2542FDT-E/MNY is a high-speed CAN FD transceiver designed for data rates up to 8Mbps. It provides the interface between a CAN protocol controller and the physical two-wire CAN bus, supporting both classical CAN and CAN Flexible Data-rate (CAN FD) frames. This automotive-qualified device features a Vio pin for direct level shifting to low-voltage microcontrollers and extremely low standby current consumption.

Why Choose This Part

This transceiver supports high-speed CAN FD communication up to 8Mbps while maintaining a very low standby current of 0.3uA. The integrated Vio pin allows for seamless 1.8V to 5V I/O interfacing without external level shifters, and the 2x3 TDFN package provides a compact footprint with high ESD protection.

Applications

Getting Started

To evaluate this part, use a CAN FD controller like the MCP2518FD or an integrated MCU with CAN FD peripheral. Ensure the VDD supply is between 4.5V and 5.5V, and match the Vio pin to your microcontroller's logic level. Use a 120-ohm termination resistor at both ends of the CAN bus for proper signal integrity.
