Microchip Technology MCP2561FD CAN FD Transceivers

Microchip MCP2561FD CAN FD Transceivers are second-generation high-speed CAN transceivers that offer the same features as the MCP2561/2. The transceivers guarantee Loop Delay Symmetry in order to support the higher data rates required for CAN FD. The maximum propagation delay was improved to support a longer bus length. The device family members are MCP2561FD with SPLIT pin and MCP2562FD with VIO pin.
