Product details
Overview
R7FA6M5BG3CFC from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 1.5 MB dual-bank code flash, 8 KB data flash, 512 KB SRAM with ECC/parity, integrated Ethernet MAC, USB 2.0 High-Speed and Full-Speed, dual CAN FD, QSPI/OSPI, and Secure Crypto Engine (SCE9) with TrustZone support. It targets industrial gateways requiring secure, real-time connectivity and deterministic control.
For engineers reviewing the R7FA6M5BG3CFC datasheet, R7FA6M5BG3CFC pinout, R7FA6M5BG3CFC application, or R7FA6M5BG3CFC equivalent, key selection considerations include its -40°C to +105°C operation, 176-pin LQFP package, dual CAN FD interface, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet MAC with RMII support - all critical for secure edge node design.
Technical Context
The R7FA6M5BG3CFC implements Armv8-M architecture with TrustZone-enabled secure/non-secure execution environments, supporting PMSAv8 memory protection with eight regions each for secure and non-secure MPU. Its dual-bank flash enables background programming and SWAP operations without halting CPU execution.
It integrates a full-featured peripheral set including ETHERC/EDMAC for zero-CPU packet handling, two independent CAN FD controllers (16 TX/16 RX buffers per channel), and SCE9 crypto engine with tamper detection, 128-bit unique ID, and resistance to power analysis - all coordinated under lifecycle-managed device security policies.

FAQ
What is the maximum operating frequency and core architecture of the R7FA6M5BG3CFC?
The R7FA6M5BG3CFC features an Arm Cortex-M33 core operating at up to 200 MHz, implementing the Armv8-M architecture with security extensions. It includes dual instances of the SysTick timer (secure and non-secure), CoreSight ETM-M33 trace, and PMSAv8 memory protection - enabling deterministic real-time performance with hardware-enforced security boundaries in the R7FA6M5BG3CFC.
Does the R7FA6M5BG3CFC support Ethernet connectivity, and what interface does it use?
Yes, the R7FA6M5BG3CFC integrates an IEEE 802.3-compliant Ethernet MAC (ETHERC) with dedicated Ethernet DMA Controller (EDMAC). It supports RMII interface only - requiring external PHY with 2-bit TX/RX data, TX_EN, and CRS_DV signals - and does not support MII or RGMII. This configuration reduces pin count and simplifies layout while maintaining 10/100 Mbps throughput in the R7FA6M5BG3CFC.
How does the Secure Crypto Engine (SCE9) in the R7FA6M5BG3CFC enhance system security?
The SCE9 in the R7FA6M5BG3CFC provides hardware-accelerated cryptographic operations including AES-128/256, RSA-2048/4096, ECC-256/384, and SHA224/256, plus tamper detection on three dedicated pins and resistance to power analysis attacks. It works in concert with Arm TrustZone to isolate secure key storage and cryptographic operations from non-secure firmware - a foundational capability for secure boot and TLS in the R7FA6M5BG3CFC.
What are the flash memory configurations supported by the R7FA6M5BG3CFC?
The R7FA6M5BG3CFC contains 1.5 MB of dual-bank code flash memory supporting background programming and atomic SWAP operations, plus 8 KB of data flash rated for 100,000 program/erase cycles. The dual-bank architecture allows one bank to execute code while the other is being reprogrammed - essential for fail-safe firmware updates in mission-critical deployments of the R7FA6M5BG3CFC.
Which package and temperature grade does the R7FA6M5BG3CFC use?
The R7FA6M5BG3CFC uses a 176-pin LQFP package (PLQP0176KB-C, 24 mm × 24 mm, 0.5 mm pitch) and is rated for industrial temperature operation from -40°C to +105°C. Its lead finish is Pb-free Sn (tin), and it complies with RoHS directives - making the R7FA6M5BG3CFC suitable for high-reliability applications in demanding thermal environments.
