8.7 CAN FD
8.7.1 Description
The STM32H7B3I-EVAL Evaluation board supports one channel of flexible data rate CAN, CAN
‑
FD compliant bus
communication based on 3.3 V CAN transceiver.
To use CAN FD, fit SB36 and SB35 solder bridges (And remove these solder bridges when using USB OTG FS,
to avoid stubs).
Standby signal on CAN
‑
FD transceiver is controlled by MFX IO9.
8.7.2 Operating voltage
STM32H7B3LIH6QU CAN
‑
FD interface can only be at 3.3 V on this board. The CAN
‑
FD MCP2562FDT-H/SN
transceiver (U28) requires 5 V on the VDD pin.
8.7.3 Limitations and hardware configuration
Limitation with primary function USB OTG FS
