MCP2542FD/4FD,
MCP2542WFD/4WFD
CAN FD Transceiver with Wake-Up Pattern (WUP) Option
Features
• 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:
- Wake-up on CAN activity, 3.6 µs filter time
• MCP2542WFD/4WFD:
- Wake-up on Pattern (WUP), as specified in
ISO11898-2:2015, 3.6 µs activity filter time
• Implements ISO11898-2:2003, ISO11898-5:2007, and
ISO/DIS11898-2:2015
• Qualification: AEC-Q100 Rev. G, Grade 0 (-40°C to
+150°C)
• 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
- An unpowered node or brown-out event will not
load the CAN bus
- Device is unpowered if VDD or VIO drop below its
POR level
• Detection of Ground Fault:
- Permanent Dominant detection on TXD
- Permanent Dominant detection on bus
• Automatic Thermal Shutdown Protection
• Suitable for 12V and 24V Systems
• Meets or Exceeds Stringent Automotive Design
Requirements Including “Hardware Requirements for
LIN, CAN and FlexRay Interfaces in Automotive
Applications”, Version 1.3, May 2012
- Conducted emissions @ 2 Mbps with
Common-Mode Choke (CMC)
- Direct Power Injection (DPI) @ 2 Mbps with CMC
• Meets SAE J2962/2 “Communication Transceiver Quali-
fication Requirements - CAN
- Radiated emissions @ 2 Mbps without a CMC
• High Electrostatic Discharge (ESD) Protection on CANH
and CANL, meeting IEC61000-4-2 up to ±13 kV
• Temperature ranges:
- Extended (E): -40°C to +125°C
- High (H): -40°C to +150°C
Description
The MCP2542FD/4FD and MCP2542WFD/4WFD CAN
transceiver family is designed for high-speed CAN FD
applications 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).
Applications
CAN 2.0 and CAN FD networks in Automotive, Industrial,
Aerospace, Medical, and Consumer applications.
