Key Features
- Standalone CAN FD controller with SPI host interface for easy integration with any microcontroller lacking on-chip CAN
- Up to 0.625 MBps CAN FD data phase rate with 40 MHz SPI clock for high-throughput network nodes
- Integrated low-power mode for battery-powered and sleep-capable automotive ECUs and industrial IoT nodes
- 28-pin VQFN package enabling compact CAN network interface designs with minimal PCB footprint
Applications
The MCP251863T-H/9PX enables any SPI-equipped microcontroller to connect to a CAN FD network, making it ideal for automotive ECUs, body control modules, and ADAS sensor nodes that require CAN FD at up to 0.625 MBps without an integrated CAN controller. It is also used in industrial automation gateways, robotics, and factory fieldbus nodes where a standalone 28-pin VQFN CAN FD interface with low-power standby reduces system BOM cost. The SPI interface at up to 40 MHz ensures fast frame processing and minimal latency in real-time control networks.

Frequently Asked Questions
What maximum CAN FD data transfer rate does the MCP251863T-H/9PX support, and how does it connect to a host microcontroller?
The MCP251863T-H/9PX supports a maximum CAN FD data phase bit rate of 0.625 MBps (625 kbps) and interfaces to the host microcontroller through a standard SPI bus running at up to 40 MHz. This SPI connection allows any microcontroller without a built-in CAN FD controller, including popular ARM Cortex-M0 or PIC devices, to join a CAN FD network with minimal firmware overhead.
How does the low-power mode of the MCP251863T-H/9PX benefit automotive ECU designs?
In low-power standby mode, the MCP251863T-H/9PX significantly reduces supply current, allowing the CAN FD node to remain on the bus and wake up on a received CAN frame while consuming minimal power. This is essential for automotive body electronics and telematics modules that must stay connected to a 12 V CAN network during vehicle sleep cycles lasting many hours without draining the battery.
Which applications are best served by using the MCP251863T-H/9PX as an external CAN FD controller instead of an MCU with integrated CAN?
The MCP251863T-H/9PX is ideal when the chosen MCU lacks an integrated CAN FD peripheral, when adding a second isolated CAN FD channel is needed, or when migrating an existing SPI-based design to CAN FD at 0.625 MBps without changing the host MCU. Industrial robots, EV battery management systems, and ADAS radar nodes often use this approach to add CAN FD without redesigning the entire control board.
How does the 28-pin VQFN package of the MCP251863T-H/9PX compare to a DIP package for modern PCB designs?
The 28-pin VQFN package measures approximately 5 mm × 5 mm with a 0.5 mm pitch, offering roughly 70% less PCB area than a 28-pin DIP package. This compact size is well matched to modern automotive and industrial PCB designs where component density is high, and the exposed thermal pad of the VQFN improves heat dissipation during continuous CAN FD frame transmission at 40 MHz SPI rates.
