SPI CANFD is a low cost, compact SPI to CANFD controller that can be easily added to a microcontroller system via the SPI interface. It uses MCP25 18FD as control cores, delivering CAN FD capability with a simple integration path. Key benefits - Low cost and compact module that enables CAN FD in budget- and space-constrained designs. - Easy SPI integration with common microcontrollers for rapid development. - Reliable CAN FD communication with scalable buffering through configurable FIFOs. What it does - Supports arbitration bitrates up to 1 Mbps and data bitrates up to 8 Mbps for flexible CAN FD operation. - Enables CAN FD communication while maintaining compatibility with standard CAN FD workflows. Power and efficiency - Very low power consumption, 15uA in sleep mode, helping to reduce system power when idle. FIFOs and timing - 31 configurable send or receive FIFOs to manage CAN traffic efficiently. - Send event FIFOs with 32-bit timestamps for precise event logging and tracing. Compatibility and form factor - Designed to connect to a microcontroller via SPI, suitable for automotive, industrial, and embedded projects that require CAN FD support. - Compact module appropriate for space-limited boards and assemblies. Use scenarios - Automotive CAN FD gateway or interface, enabling reliable vehicle network connectivity. - Industrial automation node that aggregates and relays CAN FD sensor and actuator data. - CAN FD data logger or trace module that records timestamped CAN events for diagnostics and analysis.
