MICROCHIP MCP2544FDT-H/MF

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).

• 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 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:
  • 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 Qualification 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

• CAN 2.0 and CAN FD networks in automotive
• CAN 2.0 and CAN FD networks in industrial
• CAN 2.0 and CAN FD networks in medical
