SPI CANFD is a low-cost, compact SPI to CAN FD controller. It uses MCP25 18FD as the control core and can be easily added to a microcontroller system via the SPI. The module consumes very little power, 15 uA when sleeping. It features 31 configurable send or receive FIFOs and send event FIFOs with 32-bit timestamps. Arbitration bitrates up to 1 Mbps and data bitrates up to 8 Mbps are supported. Key benefits - Simple integration: SPI interface with any microcontroller; plug-and-play in many designs - Flexible data handling: 31 configurable FIFOs plus timestamped send events for precise logging - Efficient power use: only 15 uA in sleep for battery-backed or always-on systems - High performance CAN FD: supports arbitration up to 1 Mbps and data up to 8 Mbps - Compact design: small form factor suitable for space-constrained projects Applications and scenarios - Automotive CAN FD networks: connect ECUs, sensors, and controllers with reliable, timestamped messaging - Industrial automation and machine control: robust CAN FD communication in PLCs and motor drives - Data logging and telemetry: capture and timestamp CAN FD events for diagnostics and remote monitoring This description preserves the original product features and specifications while presenting clear, customer-focused benefits and practical use cases.
