MCHPMCP2561FD-H/SN

Overview

The MCP2561FD-H/SN is a high-speed CAN Flexible Data Rate (CAN FD) transceiver designed for communication at rates up to 8Mbps. It serves as the physical interface between a CAN protocol controller and the physical two-wire bus, featuring a standby mode with ultra-low current consumption of 5uA. This specific H-variant is rated for high-temperature operation up to 150 degrees Celsius, making it suitable for demanding thermal environments.

Why Choose This Part

This transceiver supports CAN FD data rates up to 8Mbps while maintaining compatibility with legacy CAN 2.0 systems. It features permanent dominant detection to prevent bus lockup and provides high ESD protection on the CANH and CANL lines. The 1.8V to 5.5V logic interface range ensures seamless integration with a wide variety of microcontrollers without level shifters.

Applications

Getting Started

To evaluate this part, use the MCP2561FD Click board or the CAN FD PICtail Plus Daughter Board. Connect the TXD and RXD pins to your microcontroller's CAN peripheral and ensure a 5V supply is provided to VDD. For improved EMC performance, utilize the SPLIT pin for bus common-mode stabilization with a split-termination network.
