MCP2561/2FD High-Speed CAN Flexible Data Rate Transceiver Features: Description: Optimized for CAN FD (Flexible Data rate) at 2, 5 The MCP2561/2FD is a second generation high-speed and 8 Mbps Operation CAN transceiver from Microchip Technology Inc. It - Maximum Propagation Delay: 120 ns offers the same features as the MCP2561/2. Additionally, it guarantees Loop Delay Symmetry in - Loop Delay Symmetry: -10%/+10% (2 Mbps) order to support the higher data rates required for CAN Implements ISO-11898-2 and ISO-11898-5 FD. The maximum propagation delay was improved to Standard Physical Layer Requirements support longer bus length. Very Low Standby Current (5 A, typical) The device meets the automotive requirements for VIO Supply Pin to Interface Directly to CAN FD bit rates exceeding 2 Mbps, low quiescent CAN Controllers and Microcontrollers with current, electromagnetic compatibility (EMC) and 1.8V to 5.5V I/O electrostatic discharge (ESD).
