Supports arbitration bitrates up to 1 Mbps and data bitrates up to 8 Mbps on CAN FD. SPI CANFD is a low-cost, compact SPI to CAN FD controller. The controller uses MCP25 18FD as control cores and can be easily added to a microcontroller system via the SPI. The module consumes very little power, 15 uA when sleeping. It has 31 configurable send or receive FIFOs and send event FIFOs with 32-bit timestamp. Key benefits - Easy integration with existing microcontroller projects via SPI, enabling CAN FD connectivity without large changes. - High CAN FD performance with fast arbitration and data rates up to 1 Mbps (arbitration) and 8 Mbps (data). - Flexible FIFO architecture: 31 configurable send/receive FIFOs plus 32-bit timestamped event FIFOs for precise timing and event tracking. - Low-power design suitable for battery-powered, remote, or field-deployed applications. - Small, cost-effective solution that uses the MCP25 18FD cores for reliable control. What makes it stand out - Compact, affordable SPI to CAN FD solution with precise timing support and low sleep power consumption. Use scenarios - Industrial automation: connect multiple CAN FD sensors and actuators to a central controller with reliable, timestamped messaging. - Automotive embedded systems: add CAN FD capability to an ECU or test bench for high-speed data logging and diagnostics. - Remote monitoring gateway: deploy at the edge to collect CAN FD data and interface with cloud or local data processing, preserving low power in sleep mode.
