MCP2561FD

The MCP2561FD is a high-speed CAN transceiver designed for robust and reliable communication in automotive, industrial, and consumer applications. It supports data rates up to 5 Mbps, making it suitable for demanding environments where fast and accurate message transmission is critical. The device complies with the ISO 11898-2 standard for high-speed CAN, ensuring compatibility with industry-standard protocols and systems. This transceiver features a wide supply voltage range of 3.0 V to 5.5 V, enabling flexibility across various power domains. Its low-power operation mode reduces quiescent current to less than 10 µA in sleep mode, optimizing energy efficiency in battery-powered or power-sensitive designs. Additionally, the MCP2561FD includes integrated protection mechanisms such as overvoltage, short-circuit, and electrostatic discharge (ESD) protection, enhancing durability in harsh electrical environments. The chip supports both single-ended and differential signaling modes, allowing versatile integration into existing CAN network architectures. It provides a high Common Mode Rejection Ratio (CMRR), minimizing noise interference and improving signal integrity in electrically noisy conditions typical in automotive and industrial settings. The device also includes a wake-up function triggered by CAN activity, which helps maintain system responsiveness while conserving power during idle periods. Designed for ease of use, the MCP2561FD requires no external components for basic operation and offers a compact 8-pin SOIC package, simplifying PCB layout and reducing overall system cost. It interfaces seamlessly with microcontrollers and CAN controllers, such as Microchip’s PIC and dsPIC families, as well as third-party devices compliant with the CAN protocol stack. Its primary applications include automotive body control modules, engine management systems, industrial automation equipment, medical devices, and smart home systems—any environment requiring resilient, high-speed serial communication. The MCP2561FD ensures reliable performance under extreme temperatures, from -40°C to +125°C, making it ideal for deployment in both indoor and outdoor operational scenarios.
