MCP2517FD-H/SL 概要
A CAN FD controller is a protocol-specific semiconductor that organizes arbitration frames, data frames, bit timing, error handling, interrupts, and transmit buffers. It operates above the physical-layer transceiver in the CAN node hierarchy: microcontroller, MCP2517FD controller, CAN transceiver, and bus. This controller requires an external transceiver such as the ATA6563 used on Microchip's MCP2517FD Click board; CAN RXD and CAN TXD are controller-side signals, not direct bus connections.
Verified features include a 2.7 V to 5.5 V supply range, automatic retransmission control, monitor mode, and low-power mode. Automatic retransmission supports recovery from failed transmissions, while monitor mode permits observation without normal participation. Low-power mode can reduce activity when the network is idle, although the complete node power budget also depends on the MCU, SPI activity, clock source, and external transceiver.
The SPI host interface makes the controller suitable for industrial automation, automotive electronics, transportation systems, medical equipment, robotics, and embedded gateways. The CAN FD architecture supports migration from classic CAN while retaining efficient handling of higher-bandwidth payloads. Firmware must initialize bit timing, configure GPIO and interrupt behavior, select arbitration versus data-phase bit rates, and manage the controller's message objects.
PCB placement requires short SPI traces, a clean ground reference, careful decoupling, and separation from high-energy transceiver and bus routing. The controller and transceiver should share a compatible ground reference, while CANH and CANL routing should remain tightly coupled. Power and signal integrity depend on component placement, loop area, supply impedance, and the external transceiver implementation.
This page combines verified manufacturer and distributor information, procurement data, application guidance, and replacement analysis. Because the supplied sources do not expose complete electrical tables, timing limits, pin functions, or a qualified drop-in equivalent list, unsupported details are explicitly marked rather than inferred.

主な用途
MCP2517FD-H/SL の用途: 6 件s: Industrial Automation Controller, Automotive CAN FD Gateway, Robotics and Motion Control, Medical Device Interface, Embedded Gateway and Data Logger, IoT Edge Node.
Industrial Automation Controller
The MCP2517FD-H/SL fits an MCU-based automation node when the MCU already provides SPI but needs a separate CAN FD channel. Its verified 2.7 V to 5.5 V operating range supports common embedded supply systems, while the 8 Mbps capability provides bandwidth for sensor, actuator, and diagnostic traffic. The MCU configures message objects and bit timing through SPI, then connects the controller to a suitable external transceiver such as the ATA6563 used on Microchip's Click reference board. This split architecture keeps the CAN network interface modular, but firmware must handle filtering, arbitration, interrupts, fault recovery, and transceiver standby before deployment.
おすすめ
Automotive CAN FD Gateway
The MCP2517FD-H/SL can serve as the protocol controller in an automotive electronics module that uses an MCU with SPI rather than an integrated CAN FD peripheral. The verified 8 Mbps rate and CAN 2.0 compatibility support a transition path for diagnostic and control traffic, while monitor mode can help during development or network observation. Automotive use requires additional qualification verification because the supplied snippets do not state temperature limits, AEC-Q100 status, transient ratings, or isolation. Firmware and hardware must also coordinate wake-up, bus fault handling, and transceiver protection.
おすすめ
Robotics and Motion Control
A robot controller can add a CAN FD link to a microcontroller through the MCP2517FD-H/SL when distributed motor and sensor nodes need higher payload bandwidth than classic CAN. The controller's SPI host interface keeps the connection compact, and the verified low-power mode can support systems that reduce activity during idle intervals. The CAN FD channel should connect through an external transceiver, not directly to the bus. Firmware must define message identifiers, configure nominal and data-phase timing, handle arbitration, and coordinate emergency-stop or fault signaling with the robot's safety controller.
おすすめ
Medical Device Interface
The MCP2517FD-H/SL can support a distributed medical instrument when reliable control and diagnostic traffic must be carried over a CAN FD network. Its SPI architecture allows an existing embedded controller to add network connectivity without a dedicated CAN-capable MCU. The controller itself is not a medical-safety device, and the supplied data does not verify medical certification, isolation, temperature range, or electrical safety compliance. A medical design must therefore qualify the complete node, including isolation strategy, transceiver selection, grounding, watchdog behavior, fault containment, and risk controls.
おすすめ
Embedded Gateway and Data Logger
The MCP2517FD-H/SL is suitable for a gateway that collects equipment data and forwards it through a CAN FD segment. The 8 Mbps capability can reduce transfer bottlenecks when compared with low-rate serial links, while SPI allows the gateway MCU to manage configuration and buffering. Monitor mode is useful for passive network analysis or commissioning, and low-power mode can help with battery-powered or duty-cycled installations. Storage and forwarding software must still handle message loss, bus-off recovery, timestamp accuracy, and throughput limits from the MCU and transceiver.
おすすめ
IoT Edge Node
The MCP2517FD-H/SL can add CAN FD to an IoT edge node that monitors actuators, sensors, or machinery and then aggregates data for a higher-level network. Its small 14-pin SOIC package and SPI interface suit compact embedded boards, while the verified 2.7 V to 5.5 V range allows integration with common digital rails. CAN FD does not replace Ethernet or wireless connectivity; it provides a robust local control and sensing bus. Firmware should use filtering and interrupts selectively to avoid excessive MCU wake-ups, and the PCB should separate sensitive SPI routing from the transceiver's high-current switching environment.

設計ノート
Place the MCP2517FD-H/SL close to the host MCU's SPI pins and route the interface over a continuous ground reference. Keep the controller's supply bypass capacitor at the device pins and use the shortest practical connection to the local ground plane. The verified data confirms a 14-pin SOIC package but does not provide exact pin names or capacitance values, so those details must be taken from the manufacturer datasheet before layout release.
Do not connect the MCP2517FD-H/SL CAN TXD and CAN RXD signals directly to a physical CAN bus. The controller requires an external CAN transceiver; Microchip's reference click board pairs the controller with an ATA6563. Also verify that MCU SPI mode, clock polarity, interrupt polarity, reset behavior, and CAN bit timing match the firmware before power-up. The supplied search results do not expose the complete timing table, so unsupported assumptions are unsafe.
Route CANH and CANL as a closely coupled pair, maintain the transceiver's recommended termination and layout, and keep noisy switching paths away from SPI, clock, and reset traces. The controller's low-power behavior can reduce activity, but the external transceiver may dominate current consumption and switching behavior. Review grounding, return paths, and isolation strategy as a complete CAN node rather than treating the controller package as an isolated RF-like block.
Check SPI timing and CAN controller timing against the actual MCU clock. The verified operating range is 2.7 V to 5.5 V, but supply tolerance, clock accuracy, trace loading, and transceiver propagation delay can still limit the achievable bus rate. Use oscillator and bit-timing calculations from the manufacturer documentation, test bus timing with the selected transceiver, and verify error counters and bus-off recovery before production.
Design the power rail for the complete CAN node, including the MCU, MCP2517FD-H/SL, external transceiver, and any interface adapters. The verified data confirms a 2.7 V to 5.5 V controller supply range and low-power mode, but it does not provide exact current values. Measure worst-case startup, transmit, receive, idle, and sleep consumption rather than estimating from the mode name alone.
コンプライアンス情報
The supplied search results do not provide verified compliance declarations for the exact MCP2517FD-H/SL orderable part. Check the manufacturer product page, datasheet, and material declaration before procurement.
