MCHPMCP2542FDT-E/SN

Overview

The MCP2542FDT-E/SN is a high-speed CAN FD transceiver designed for high-speed communication up to 8Mbps. It serves as the interface between a CAN protocol controller and the physical two-wire CAN bus, providing differential transmit and receive capability. This part is optimized for low quiescent current, with a typical standby current of only 4uA and a wide supply voltage range of 4.5V to 5.5V.

Why Choose This Part

This transceiver supports the high data rates required by CAN FD up to 8Mbps while maintaining a low standby current of 4uA. It features a high receiver hysteresis of 200mV for improved noise rejection and is rated for extended temperatures up to 125 degrees Celsius, making it suitable for harsh environments.

Applications

Getting Started

Engineers can evaluate this part using Microchip's CAN FD development boards or by integrating the 8-SOIC package into a prototype using a standard 1.27mm pitch breakout. Ensure the VDD supply is between 4.5V and 5.5V, and place a decoupling capacitor close to the supply pin to manage the 55mA dominant state current spikes.
