MCP2517FD-H/JHA Présentation
A CAN FD Controller is a peripheral IC that implements the ISO 11898-1 CAN 2.0B and CAN FD (Flexible Data-rate) physical layer signaling and frame handling independently of the host microcontroller. It sits between an MCU's SPI bus and an external CAN transceiver, allowing designers to add a CAN FD channel to any microcontroller that already has an SPI master, including legacy MCUs and low-cost MCUs without built-in CAN FD peripherals. CAN FD extends classic CAN by increasing payload from 8 bytes to 64 bytes and allowing a switched, higher data-bit-rate phase after arbitration.
Key features include 8 Mbps maximum CAN FD bit rate, up to 40 MHz SPI clock, configurable GPIO pins, integrated time-stamping, hardware filtering of acceptance frames, low-power standby mode, 5V-tolerant I/O, and 3.3V or 5V supply operation. Two interrupt outputs simplify real-time interrupt-driven designs and dual-MCU bus arbitration. The exposed pad on the VDFN package provides a low thermal resistance path for high-temperature environments.
Architecturally, the MCP2517FD pairs a CAN protocol engine with a 2 KB message RAM that can be partitioned between transmit and receive FIFOs, with up to 32 acceptance filters. SPI transactions configure transmit/receive queues, retrieve error counters, and access the 32-bit time-stamp counter. Status reporting, bus-error counting, and ISO 26262 functional-safety diagnostics are integrated into the interrupt and register architecture.
Typical applications include automotive body and chassis ECUs that require an extra CAN FD channel beyond the MCU's built-in peripherals, industrial PLCs and sensor nodes, agricultural and off-highway equipment, EV battery management, and any retrofit design adding CAN FD to an MCU without CAN FD hardware. Designers pair the MCP2517FD-H/JHA with a high-speed CAN FD transceiver such as the ATA6563 or MCP2562FD.
Designers should pair the MCP2517FD-H/JHA with a 3.3V LDO and place bypass capacitors as close as possible to VDD. The exposed pad must be soldered to a sufficient copper pour for thermal relief up to 150C ambient.

Applications typiques
MCP2517FD-H/JHA convient pour 6 applications: Automotive Body/Chassis ECU, Industrial PLC and Sensor Node, EV Battery Management Systems, Agricultural and Off-Highway Equipment, Retrofit CAN FD Adapter for Legacy MCUs, Functional-Safety Automotive Gateway.
Automotive Body/Chassis ECU
The MCP2517FD-H/JHA adds a CAN FD channel to body and chassis ECUs that need more CAN ports than the host MCU provides. With 8 Mbps CAN FD bit rate, 2 KB message RAM, and -40C to +150C operating range, this controller fits AEC-Q100-style automotive thermal envelopes while offloading the protocol layer from the main MCU. It is paired with a high-speed CAN FD transceiver such as the ATA6563 to drive a physical bus shared with body-control modules, lighting controllers, and door modules. Two interrupt outputs reduce host polling while configurable FIFOs and acceptance filters tame heavy gateway traffic. The exposed pad of the 14-VDFN EP keeps junction temperature low even in sealed under-hood enclosures.
Recommandé
Industrial PLC and Sensor Node
The MCP2517FD-H/JHA is well-suited for industrial PLCs and remote sensor nodes that already carry an SPI-capable MCU and need CAN FD bus connectivity for factory automation. The 5V-tolerant I/O and 40 MHz SPI clock allow direct connection to legacy 5V industrial microcontrollers, while 3.3V MCUs are equally supported. The 2 KB of FIFO-configurable message RAM and 32 acceptance filters drop the interrupt load on the host MCU, letting low-cost Cortex-M0 parts handle heavier CAN traffic. Functional-safety capability to ISO 26262 ASIL B supports safety-related industrial protocols. The 14-VDFN EP package is compact enough for DIN-rail-mounted field modules.
Recommandé
EV Battery Management Systems
In electric vehicle battery management, the MCP2517FD-H/JHA acts as a CAN FD bridge between battery-monitoring MCUs and the vehicle CAN FD backbone. Its 8 Mbps CAN FD bit rate carries the larger 64-byte battery-cell telemetry payloads demanded by modern BMS firmware, while the 2 KB message RAM absorbs transient burst traffic during cell-balancing events. SPI up to 40 MHz lets the master BMS MCU offload CAN protocol handling entirely to the MCP2517FD, freeing CPU cycles for cell-voltage computation and state-of-charge algorithms. The +150C maximum junction temperature enables placement near pack-level PCBs where ambient temperatures peak during fast-charge cycles.
Recommandé
Agricultural and Off-Highway Equipment
Off-highway machinery such as tractors, harvesters, and construction equipment uses CAN FD to link implements, GPS units, and telematics controllers. The MCP2517FD-H/JHA's -40C to +150C operating range tolerates the thermal swings of an open cab or engine-bay environment. Designers add a CAN FD port to existing 5V MCUs without redesigning the host processor, keeping the BOM cost down. The exposed-pad VDFN EP package handles vibration-induced thermal cycling better than larger QFP alternatives. The MCP2517FD pairs with ruggedized transceivers like the MCP2562FD to meet ISO 11783 agricultural bus requirements.
Recommandé
Retrofit CAN FD Adapter for Legacy MCUs
When an existing product built around an MCU without a CAN FD peripheral needs to add CAN FD connectivity, the MCP2517FD-H/JHA is a low-risk drop-in expansion. Any SPI-equipped MCU - even an 8-bit AVR or legacy PIC - can drive the MCP2517FD-H/JHA with its documented register interface, avoiding a costly host-MCU swap. The 5V-tolerant I/O bridges old 5V logic to a modern CAN FD bus seamlessly. The 14-VDFN EP footprint fits in the spare area of retrofit adapter PCBs. The MCP2517FD's well-validated driver libraries from Microchip accelerate development across GCC, IAR, MPLAB X, and Keil toolchains.

Notes de conception
Estimated: with a 3.3V LDO supplying VDD and room-temperature operation, the MCP2517FD-H/JHA draws low tens of mA in active mode and microamp-level current in standby. Place a 1uF X7R ceramic bypass capacitor within 5 mm of the VDD pin and a 100 nF decoupling cap immediately adjacent to the IC. The exposed pad must be soldered to a copper pour of at least 1 cm^2 on a 2-layer board to keep junction temperature below +150C under high CAN bus traffic. Add a 10 kohm pull-up on the RESET pin if external MCU-driven reset is unused.
Route the SCK, MOSI, MISO, and CS lines as short matched traces (<50 mm) over a continuous ground plane to avoid SPI ringing. Keep TXCAN/RXCAN traces matched in length within 5 mm and routed away from switching regulator or MOSFET gate traces to prevent coupling into the CAN signal. Place the external crystal/oscillator as close to OSC_IN/OSC_OUT as practical, with load capacitors following the datasheet's oscillator cell guidelines. The MCP2517FD-H/JHA is tolerant of 5V or 3.3V SPI hosts; no level translator is required when the host MCU I/O are 5V tolerant.
Do not connect TXCAN directly to the CAN bus - you MUST use an external CAN FD transceiver (such as the ATA6563 or MCP2562FD) between the controller's logic-level TX/RX pins and the physical differential bus. Ensure the /JHA part number's 14-VDFN EP package is correctly oriented - the EPAD is pin-15 (thermally connected) and pins 1-14 are on the perimeter; the JEDEC pin-1 indicator is a white dot on top. Cross-region RoHS/REACH paperwork should be confirmed before volume import. The MCP2517FD is a controller-only IC; confirm that your MCU's SPI driver handles 40 MHz clocks before increasing bus speed.
