FAQ
What is the maximum operating frequency and core architecture of the R7FA6M1AD3CFP#BA0?
The R7FA6M1AD3CFP#BA0 features an Arm Cortex-M4 core with Floating Point Unit (FPU), operating at a maximum frequency of 120 MHz. It implements the Armv7E-M architecture with DSP instruction set and supports a 4-GB address space. This configuration delivers deterministic real-time performance for motor control, audio processing, and industrial automation tasks within the R7FA6M1AD3CFP#BA0's thermal envelope.
Does the R7FA6M1AD3CFP#BA0 support CAN FD or only classical CAN 2.0?
The R7FA6M1AD3CFP#BA0 supports Controller Area Network (CAN) 2.0A/B only, compliant with ISO 11898-1. It does not implement CAN FD (Flexible Data-Rate). Each of its two CAN modules supports up to 32 mailboxes, standard (11-bit) and extended (29-bit) identifiers, and FIFO modes - sufficient for most industrial and body-control applications but not for high-bandwidth automotive ADAS domains requiring CAN FD throughput.
What package type and pin count does the R7FA6M1AD3CFP#BA0 use?
The R7FA6M1AD3CFP#BA0 uses a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch. This package provides 67 CMOS I/O pins, 9 dedicated inputs, 14 5-V-tolerant pins, and 13 high-current (20 mA) outputs - optimized for industrial PCB layouts requiring mechanical robustness and thermal dissipation without BGA assembly complexity.
How does the Memory Mirror Function (MMF) benefit firmware updates on the R7FA6M1AD3CFP#BA0?
The Memory Mirror Function (MMF) in the R7FA6M1AD3CFP#BA0 allows application code to be linked to run from a fixed virtual address while being stored at any physical location in 512 KB code flash. This eliminates runtime relocation and simplifies over-the-air (OTA) updates, as new firmware images can be written to unused flash sectors and activated via MMF pointer reconfiguration - reducing update failure risk and minimizing downtime in field-deployed R7FA6M1AD3CFP#BA0 systems.
Is the USB interface on the R7FA6M1AD3CFP#BA0 capable of host-mode operation?
Yes, the R7FA6M1AD3CFP#BA0's USB 2.0 Full-Speed (USBFS) module supports both device and host modes, as defined in the Universal Serial Bus Specification 2.0. It includes an on-chip transceiver, supports low-speed transfers in host mode, and provides up to 10 configurable pipes. This dual-role capability enables R7FA6M1AD3CFP#BA0-based designs to act as USB peripherals (e.g., HID devices) or hosts for flash drives, keyboards, or diagnostic tools without external PHY components.
