FAQ

What is the maximum operating frequency and core architecture of the R7FA6M5BH2CBG?

The R7FA6M5BH2CBG features an Arm Cortex-M33 core operating at up to 200 MHz, based on the Armv8-M architecture with security extensions. It implements TrustZone for hardware-enforced secure/non-secure world separation and includes dual 8-region MPUs for memory protection in both domains. This architecture enables deterministic real-time performance while maintaining robust security boundaries essential for industrial and IoT deployments where the R7FA6M5BH2CBG is deployed.

Does the R7FA6M5BH2CBG support dual CAN FD, and what are the buffer configurations?

Yes, the R7FA6M5BH2CBG integrates two independent CAN FD modules compliant with ISO 11898-1, each supporting classical CAN and CAN FD frames. Each channel provides 16 dedicated transmit buffers and 16 receive buffers, enabling concurrent handling of high-priority diagnostics and high-bandwidth sensor data streams. This dual-channel capability is confirmed in the RA6M5 datasheet (R01DS0366EJ0150) and makes the R7FA6M5BH2CBG suitable for automotive gateway and industrial automation applications requiring redundant or segregated CAN networks.

What package type and pin count does the R7FA6M5BH2CBG use?

The R7FA6M5BH2CBG uses a 176-pin Fine-Pitch Ball Grid Array (FBGA) package with part code PLBG0176GF-A, measuring 7 mm × 7 mm with 0.5 mm pitch. It is rated for -40°C to +85°C operation and provides 132 general-purpose I/O pins, 17 of which are 5-V tolerant. This compact, high-density package supports automated assembly and thermal performance requirements typical of space-constrained industrial and networking equipment where the R7FA6M5BH2CBG is implemented.

How does the R7FA6M5BH2CBG implement secure firmware updates?

The R7FA6M5BH2CBG enables secure firmware updates through dual-bank code flash with SWAP operation and hardware-accelerated cryptography via the Secure Crypto Engine 9. The dual-bank architecture allows validation of a new firmware image in the inactive bank while the system runs from the active bank; upon successful signature verification (using RSA/ECC), the SWAP command atomically switches execution to the updated bank. This process is enforced by TrustZone and protected by the R7FA6M5BH2CBG's lifecycle management and tamper detection features, ensuring end-to-end integrity without external dependencies.

What are the supported clock sources and accuracy measurement capabilities of the R7FA6M5BH2CBG?

The R7FA6M5BH2CBG supports multiple clock sources: external 8–24 MHz crystal (MOSC), 32.768 kHz sub-clock (SOSC), and internal oscillators (HOCO/MOCO/LOCO/IWDT-OSC) with programmable trim. Its Clock Frequency Accuracy Measurement Circuit (CAC) verifies oscillator stability by counting target clock pulses against a reference clock, generating interrupts if deviation exceeds user-defined thresholds. This capability ensures reliable USB/Ethernet timing and is documented in the R7FA6M5BH2CBG datasheet section 1.3.3, directly supporting fail-safe operation in mission-critical systems.
