For engineers reviewing the R7FA6M5AG3CFB#BA0 datasheet, R7FA6M5AG3CFB#BA0 pinout, R7FA6M5AG3CFB#BA0 application, or R7FA6M5AG3CFB#BA0 equivalent, key selection criteria include its -40°C to +105°C operation, 144-pin LQFP package, dual CAN FD support, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet PHY interface capability via RMII.

Technical Context

The R7FA6M5AG3CFB#BA0 implements Armv8-M with TrustZone security extension, enabling strict isolation between secure and non-secure firmware execution environments. Its memory subsystem includes dual-bank flash supporting background programming and SWAP operations, plus 512 KB SRAM partitioned with 448 KB parity and 64 KB ECC protection.

Connectivity is centered on concurrent high-speed interfaces: Ethernet MAC (RMII-only), USBHS/USBFS with internal transceivers, two CAN FD controllers (16 TX/RX buffers each), SDHI, SSIE, CEC, and 10-channel SCI with UART/IIC/SPI/Manchester modes - all managed via Event Link Controller (ELC) and 8-channel DMAC for CPU-offload data movement.

FAQ

What is the maximum operating frequency of the R7FA6M5AG3CFB#BA0?

The R7FA6M5AG3CFB#BA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved via the integrated PLL driven by the main clock oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core sustains this frequency under full peripheral load within the -40°C to +105°C operating range, with voltage regulation maintained at VCC = 2.7–3.6 V.

Does the R7FA6M5AG3CFB#BA0 support Ethernet connectivity, and what interface does it use?

Yes, the R7FA6M5AG3CFB#BA0 integrates an Ethernet MAC controller compliant with IEEE 802.3, supporting 10/100 Mbps operation exclusively via the Reduced Media Independent Interface (RMII). It requires an external PHY IC but includes all MAC-layer logic, DMA integration (EDMAC), and RMII signal routing (ETXD0–3, ERXD0–3, ETXEN, ERXDV, EREF_CLK) on dedicated pins - no software stack modification is needed for standard TCP/IP implementation.

How many CAN FD channels does the R7FA6M5AG3CFB#BA0 include, and what are their capabilities?

The R7FA6M5AG3CFB#BA0 includes two fully independent CAN FD controllers compliant with ISO 11898-1. Each supports classical CAN (up to 1 Mbps) and CAN FD (up to 5 Mbps data phase), with 16 dedicated transmit buffers and 16 receive buffers per channel. Both channels support bit-rate switching, flexible data-length (up to 64 bytes), and hardware message filtering - enabling simultaneous high-bandwidth vehicle diagnostics and real-time actuator control in industrial networks.

What security features are implemented in the R7FA6M5AG3CFB#BA0 beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5AG3CFB#BA0 integrates the Secure Crypto Engine (SCE9) with hardware-accelerated AES-128/256, RSA-2048/4096, ECC-P256/P384, SHA256, and GHASH. It also provides tamper detection pins, secure key management with protected storage, power analysis resistance, and a 128-bit unique ID fused at manufacture - collectively enabling PSA Certified Level 2 compliance and secure boot, firmware authentication, and TLS offload without external secure elements.

Is the R7FA6M5AG3CFB#BA0 pin-compatible with other RA6M5 variants in the same package?

Yes, the R7FA6M5AG3CFB#BA0 is fully pin-compatible with all other RA6M5 Group members in the 144-pin LQFP package (e.g., R7FA6M5AH3CFB#BA0, R7FA6M5BG3CFB#BA0), sharing identical pin functions, electrical characteristics, and mechanical footprint. This allows direct substitution for flash capacity scaling or feature reduction without PCB redesign - provided the target variant's peripheral enablement (e.g., OSPI, second CAN FD) matches the design requirements.
