FAQ

What is the maximum operating frequency and core architecture of the R7FA6M4AD3CBQ#BC0?

The R7FA6M4AD3CBQ#BC0 features an Arm Cortex-M33 core running at a maximum frequency of 200 MHz. It implements the Armv8-M architecture with TrustZone security extension (r0p4-00rel0 revision), including dual SysTick timers (secure and non-secure instances) and CoreSight ETM-M33 for trace debugging. This architecture enables hardware-isolated secure execution environments critical for firmware integrity in connected devices.

Does the R7FA6M4AD3CBQ#BC0 support Ethernet communication, and what interface does it use?

Yes, the R7FA6M4AD3CBQ#BC0 integrates a single-channel IEEE 802.3-compliant Ethernet MAC (ETHERC) with an associated Ethernet DMA Controller (EDMAC). It supports RMII physical interface only and requires an external PHY (e.g., LAN8742A) for physical layer connectivity. The ETHERC/EDMAC combination enables zero-CPU packet handling, making it suitable for real-time industrial protocols like EtherNet/IP or PROFINET IRT.

What security features are implemented in the R7FA6M4AD3CBQ#BC0 beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M4AD3CBQ#BC0 includes the Secure Crypto Engine 9 (SCE9) with hardware-accelerated AES-128/256, RSA-2048/4096, ECC-256/384, and SHA224/256. It also provides tamper detection pins, 128-bit unique ID, secure key injection, lifecycle management, and secure pin multiplexing - all coordinated under TrustZone to create a certified secure element capable of PSA Certified Level 2 compliance.

What is the flash memory configuration of the R7FA6M4AD3CBQ#BC0, and how does it support firmware updates?

The R7FA6M4AD3CBQ#BC0 contains 512 KB of dual-bank code flash memory with background and SWAP operation capability. This allows one bank to execute active firmware while the other receives and validates new firmware - enabling atomic, fail-safe over-the-air (OTA) updates without system downtime or external memory. The 8 KB data flash supports 100,000 program/erase cycles for parameter storage.

Which package type and pin count does the R7FA6M4AD3CBQ#BC0 use, and what are its thermal specifications?

The R7FA6M4AD3CBQ#BC0 uses a 64-pin Fine-Pitch Ball Grid Array (FBGA) package with 0.50 mm pitch and 7 mm × 7 mm body size (PLBG0064JC-A). It operates across an industrial temperature range of -40°C to +105°C and is rated for 2.7–3.6 V supply voltage. Its compact BGA footprint supports high-density PCB layouts while maintaining thermal performance in sealed enclosures.
