Renesas R7FA6M5AH2CBG#BC0

Overview

R7FA6M5AH2CBG 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 industrial gateways and connected edge devices.

For engineers reviewing the R7FA6M5AH2CBG datasheet, R7FA6M5AH2CBG pinout, R7FA6M5AH2CBG application, or R7FA6M5AH2CBG equivalent, key selection criteria include its -40°C to +85°C operating range, 176-pin FBGA package, dual CAN FD support, integrated Ethernet MAC with RMII, and hardware-accelerated cryptography (AES/RSA/ECC/SHA256) for secure firmware updates and device authentication.

Technical Context

The R7FA6M5AH2CBG implements Armv8-M architecture with TrustZone security extension, enabling strict isolation between secure and non-secure execution environments. Its dual-bank flash supports seamless firmware updates via SWAP operation without system interruption, while the SCE9 crypto engine offloads AES-128/256, RSA-2048, ECC-P256, and SHA256 operations from the CPU.

It features two independent CAN FD controllers compliant with ISO 11898-1, each with 16 transmit and 16 receive buffers, and an Ethernet MAC (ETHERC) supporting RMII interface with integrated DMA (EDMAC) for zero-copy packet handling. The 200 MHz core clock is derived from PLL with multiple on-chip oscillator sources (HOCO/MOCO/LOCO/SOSC).

FAQ

What is the maximum operating frequency of the R7FA6M5AH2CBG?

The R7FA6M5AH2CBG operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This clock speed is achieved via the on-chip PLL driven by the main crystal oscillator (8–24 MHz) or high-speed on-chip oscillator (HOCO). The R7FA6M5AH2CBG maintains full peripheral functionality-including Ethernet MAC, USB HS, and dual CAN FD-at this frequency, validated across the full -40°C to +85°C temperature range.

Does the R7FA6M5AH2CBG support CAN FD, and how many channels are available?

Yes, the R7FA6M5AH2CBG supports CAN with Flexible Data-rate (CAN FD) on two independent channels, each compliant with ISO 11898-1. Each channel provides 16 transmit buffers and 16 receive buffers, enabling concurrent high-bandwidth communication on separate CAN FD networks. This capability is confirmed in the R01DS0366EJ0150 datasheet Section 1.4 and Table 1.14, distinguishing it from the 'B' variant which supports only Classical CAN.

What security features does the R7FA6M5AH2CBG include beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5AH2CBG integrates the Secure Crypto Engine 9 (SCE9) with hardware accelerators for AES-128/256, RSA-2048, ECC-P256, DSA, SHA224/256, and GHASH. It also includes tamper detection via dedicated pins, power analysis resistance, 128-bit unique ID, and device lifecycle management. These features are documented in Section 1.1 and Table 1.1 under "Security and Encryption" in the R01DS0366EJ0150 datasheet.

What package type and pin count does the R7FA6M5AH2CBG use?

The R7FA6M5AH2CBG 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 ball pitch. This package supports 132 general-purpose I/O pins, 17 of which are 5-V tolerant, and includes dedicated balls for VCC, VSS, VBATT, and high-speed interfaces including Ethernet RMII and USB HS. Package details are specified in Table 1.13 and Figure 1.2 of the R01DS0366EJ0150 datasheet.

Is the R7FA6M5AH2CBG compatible with Renesas' Flexible Software Package (FSP)?

Yes, the R7FA6M5AH2CBG is fully supported by Renesas' Flexible Software Package (FSP) v4.x and later, including drivers for all integrated peripherals-Ethernet MAC, USB HS/FS, dual CAN FD, SCE9 crypto APIs, TrustZone configuration, and secure boot. FSP provides certified middleware stacks such as AWS IoT Core SDK, Azure RTOS, and FreeRTOS with pre-integrated security services tailored for the R7FA6M5AH2CBG's hardware capabilities.
