Renesas R7FA6M5BH2CBG#AC0

Overview

R7FA6M5BH2CBG from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 2 MB dual-bank code flash with background/swap operation, 8 KB data flash, and 512 KB SRAM with parity/ECC. It integrates Ethernet MAC, USB 2.0 High-Speed/Full-Speed, dual CAN FD, SDHI, QSPI/OSPI, and Secure Crypto Engine (SCE9) with TrustZone for secure edge IoT gateways and industrial controllers.

For engineers reviewing the R7FA6M5BH2CBG datasheet, R7FA6M5BH2CBG pinout, R7FA6M5BH2CBG application, or R7FA6M5BH2CBG equivalent, key selection considerations include its -40°C to +85°C operating range, 176-pin FBGA (PLBG0176GF-A) package, dual CAN FD support, integrated Ethernet MAC with RMII interface, and hardware-accelerated AES/RSA/ECC/SHA256 cryptography.

Technical Context

The R7FA6M5BH2CBG implements Armv8-M architecture with TrustZone security extension, supporting secure/non-secure execution states via dual MPU instances (8 regions each) and configurable memory region attribution. Its system-level integration includes Event Link Controller (ELC) for CPU-free peripheral triggering and Data Transfer Controller (DTC) for interrupt-driven zero-CPU-overhead data movement.

It delivers deterministic real-time performance through eight-channel DMAC, six AGT timers for low-power event counting, and GPT32/GPT16 modules supporting BLDC motor control with complementary PWM outputs (GTOUUP/GTOULO etc.). Clock management combines PLL/PLL2, multiple on-chip oscillators (HOCO/MOCO/LOCO), and CAC for frequency accuracy validation.

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, implementing the Armv8-M architecture with security extensions including TrustZone, dual MPU instances (8 regions each), and CoreSight ETM-M33 trace. This architecture enables secure, real-time deterministic execution for industrial and IoT applications where both performance and isolation are critical. The R7FA6M5BH2CBG achieves this frequency using its integrated PLL and supports multiple clock sources including HOCO, MOSC, and PLL2.

Does the R7FA6M5BH2CBG support CAN FD, and how many channels are available?

Yes, the R7FA6M5BH2CBG supports two independent CAN FD channels compliant with ISO 11898-1, each with 16 dedicated transmit and receive buffers. This enables simultaneous high-bandwidth communication with modern automotive ECUs or industrial fieldbuses while maintaining backward compatibility with classical CAN 2.0B networks. The R7FA6M5BH2CBG's CAN FD implementation supports data rates up to 5 Mbps and payloads up to 64 bytes-essential for firmware updates and sensor fusion in distributed systems.

What security features does the R7FA6M5BH2CBG include beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5BH2CBG integrates the Secure Crypto Engine 9 (SCE9) with hardware accelerators for AES-128/256, RSA-2048/4096, ECC NIST P-256/P-384, DSA, and SHA224/SHA256/GHASH. It also provides tamper detection pins, power analysis resistance, a 128-bit unique ID, and lifecycle management for secure boot and key provisioning. These features allow the R7FA6M5BH2CBG to serve as a certified secure element in applications requiring FIPS 140-2 or Common Criteria EAL4+ compliance without external security ICs.

What is the package type and pin count of the R7FA6M5BH2CBG?

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 operation from -40°C to +85°C and provides 132 general-purpose I/O pins, 17 of which are 5-V tolerant. This compact, high-density package supports advanced routing for high-speed interfaces like USB HS, Ethernet RMII, and QSPI/OSPI while enabling miniaturized industrial and medical designs. The R7FA6M5BH2CBG's FBGA footprint is distinct from LQFP variants in the RA6M5 family.

How does the R7FA6M5BH2CBG handle firmware updates in the field?

The R7FA6M5BH2CBG supports robust over-the-air (OTA) firmware updates via its dual-bank code flash architecture, enabling background programming and atomic SWAP operations. While one bank executes the active application, the second bank receives and validates the new image-ensuring zero downtime and guaranteed rollback on failure. Combined with SCE9-verified digital signatures and TrustZone-isolated update handlers, the R7FA6M5BH2CBG guarantees authenticated, integrity-checked, and tamper-resistant field updates. This capability is foundational for deploying the R7FA6M5BH2CBG in unattended remote infrastructure.
