Renesas R7FA6M5AH3CFC#AA0

Overview

R7FA6M5AH3CFC 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, 512 KB SRAM with parity/ECC, integrated Ethernet MAC, USB 2.0 High-Speed/Full-Speed, dual CAN FD, QSPI/OSPI, SDHI, and Secure Crypto Engine (SCE9) with TrustZone for secure embedded applications in industrial gateways and connected edge devices.

For engineers reviewing the R7FA6M5AH3CFC datasheet, R7FA6M5AH3CFC pinout, R7FA6M5AH3CFC application, or R7FA6M5AH3CFC equivalent, key selection considerations include its -40°C to +105°C extended temperature rating, 176-pin LQFP package (PLQP0176KB-C), dual CAN FD support, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet MAC with RMII interface - all critical for deterministic real-time control and secure connectivity in harsh environments.

Technical Context

The R7FA6M5AH3CFC implements Armv8-M architecture with TrustZone security extension, enabling strict isolation between secure and non-secure execution states. It integrates dual 14-bit watchdog timers (WDT/IWDT), two independent SysTick timers (secure/non-secure), and an Event Link Controller (ELC) for CPU-free peripheral synchronization.

Its memory subsystem supports concurrent read-while-write flash operations via dual-bank architecture, while the 8-channel DMAC and Data Transfer Controller (DTC) offload data movement from the CPU. The SCE9 crypto engine provides dedicated hardware acceleration for AES-128/256, RSA-2048/4096, ECC (NIST P-256/P-384), and SHA-224/256, with tamper detection and 128-bit unique ID.

FAQ

What is the maximum operating frequency and core architecture of the R7FA6M5AH3CFC?

The R7FA6M5AH3CFC features an Arm Cortex-M33 core operating at up to 200 MHz, based on the Armv8-M architecture with security extension. It includes dual SysTick timers (secure and non-secure instances), CoreSight ETM-M33 trace support, and Memory Protection Unit (MPU) with eight regions each for secure and non-secure states - all confirmed in the R01DS0366EJ0150 datasheet Rev.1.50.

Does the R7FA6M5AH3CFC support CAN FD or only classical CAN?

The R7FA6M5AH3CFC supports classical CAN only, as indicated by the 'A' in its part number suffix per Renesas' RA6M5 part numbering scheme (Figure 1.2). It does not implement CAN FD functionality; for CAN FD support, select the 'B' variant such as R7FA6M5BH3CFC. This distinction is explicitly documented in Table 1.14 and Section 1.3 of the datasheet.

What package type and pin count does the R7FA6M5AH3CFC use?

The R7FA6M5AH3CFC uses a 176-pin LQFP package (PLQP0176KB-C), measuring 24 mm × 24 mm with 0.5 mm pitch, and is rated for operation from -40°C to +105°C. This is confirmed in Table 1.13 (Product List) and Figure 1.2 (Part Numbering Scheme) of the R01DS0366EJ0150 datasheet.

What security features are integrated into the R7FA6M5AH3CFC?

The R7FA6M5AH3CFC integrates the Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES-128/256, RSA-2048/4096, ECC (NIST P-256/P-384), DSA, and SHA-224/256. It also includes Arm TrustZone, tamper detection (up to three dedicated pins), 128-bit unique ID, and lifecycle management - all detailed in Section 1.1 and Table 1.14 of the official datasheet.

Is Ethernet MAC functionality available on the R7FA6M5AH3CFC, and what interface does it support?

Yes, the R7FA6M5AH3CFC includes a fully integrated IEEE 802.3-compliant Ethernet MAC controller (ETHERC) connected to the Ethernet DMA Controller (EDMAC). It supports RMII interface only (not MII), as noted in Table 1.14 footnote 3 ("Available for RMII only") and confirmed in the block diagram (Figure 1.1) and peripheral list in Section 1.1 of the datasheet.
