MCP2518FD Pro SPI to CANFD Transceiver Module ATA6560 Chip DB9 Interface High Speed CAN/CAN Bus Communication Board

✨ SPI to CANFD Module | MCP2518FD Pro Board

📌 Product Overview

This compact SPI-CANFD adapter is a cost-effective, high-performance converter built around the MCP2518FD CANFD controller + ATA6560 CAN transceiver. It connects to any MCU/embedded system via standard SPI bus to add CAN 2.0B & CAN FD communication capability without native CAN peripherals. Fully compliant with ISO 11898-1:2015 automotive & industrial standard, it supports ultra-fast 8Mbps CAN FD data bit rate, with rich built-in FIFO buffers, hardware message filtering, and industrial surge protection.

⚙️ Key Functional Features

1. SPI External CANFD Controller

• Pure SPI-driven design, compatible with all MCUs equipped with SPI peripherals
• 3 selectable working modes: CAN FD Only / CAN 2.0B Only / Mixed Hybrid Mode
• Strict ISO 11898-1:2015 compliance for automotive and industrial bus deployment

2. Message FIFO Buffer System

• 31 configurable FIFOs, freely assigned for transmit or receive tasks
• Independent TXQ transmission queue for priority frame scheduling
• TEF transmit event FIFO with native 32-bit timestamp for precise timing logging

3. Smart Transmission Control

• Frame priority sorting based on ID bit field; smaller ID transmits first via TXQ
• 3 programmable auto-retry modes: Unlimited Retries / 3 Retries / Retry Disabled

4. Multi-Level Hardware Receiving Filter

• 32 independent filter & mask objects for multi-node bus signal screening
• Supports Standard ID (18-bit data) and Extended ID two filtering formats
• All received frames carry 32-bit timestamp to eliminate software timing deviation

5. Industrial Circuit Protection

• Integrated bridge protection stack on CAN bus channel
• Shields hardware from electrostatic discharge, group pulse interference, and voltage surges

💡 Onboard Hardware & Jumper Setting

• Green power indicator LED1: Constantly lit when power supply is connected
