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.
