Product Description

The MCP2551 is a high-speed CAN transceiver, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard, including 24V requirements. It will operate at speeds of up to 1 Mb/s.

Features
    • Slope control input • Supports 1 Mb/s operation • Implements ISO-11898 standard physical layer requirements • Suitable for 12V and 24V systems • Externally-controlled slope for reduced RFI emissions • Permanent dominant detect • Low current standby operation • High noise immunity due to differential bus implementation

Product Description

The MCP2561/2FD is a Microchip Technology Inc. second generation high-speed CAN transceiver. It offers the same features as the MCP2561/2. Additionally, it guarantees Loop Delay Symmetry in order to support the higher data rates required for CAN FD. The maximum propagation delay was improved to support longer bus length.The device meets the automotive requirements for CAN FD bit rates exceeding 5 Mbps, low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge (ESD). The device family members are MCP2561FD with SPLIT pin & MCP2562FD with VIO pin
