MCP2542FD/4FD,

MCP2542WFD/4WFD

CAN FD Transceiver with Wake-up Pattern (WUP) Option

Features

Description

• Supports CAN 2.0 and CAN with Flexible

Data-Rate (CAN FD) Physical Layer Transceiver

Requirements

• Optimized for CAN FD at 2, 5 and 8 Mbps Operation:

- Maximum propagation delay: 120 ns

- Loop delay symmetry: -10%/+10% (2 Mbps)

• MCP2542FD/4FD:

The MCP2542FD/4FD and MCP2542WFD/4WFD

CAN transceiver family is designed for high-speed

CAN FD applications of up to 8 Mbps communication

speed. The maximum propagation delay was improved

to support longer bus length.

The device meets the automotive requirements for

CAN FD bit rates exceeding 2 Mbps, low quiescent

current, Electromagnetic Compatibility (EMC) and

Electrostatic Discharge (ESD).

- Wake-up on CAN activity, 3.6 µs filter time

• MCP2542WFD/4WFD:

- Wake-up on Pattern (WUP), as specified in

ISO 11898-2:2016, 3.6 µs activity filter time

• Implements ISO 11898-2:2016

• Qualified According to AEC-Q100 Rev. G

• Very Low Standby Current (4 µA, typical)

• VIO Supply Pin to Interface Directly to CAN 

Controllers and Microcontrollers with 1.8V to 5V I/O

• CAN Bus Pins are Disconnected when Device is

Unpowered:

Applications

CAN 2.0 and CAN FD networks in automotive, industrial,

aerospace, medical and consumer applications.
