Product details
Overview
R7FA6M4AD3CFM#BA5 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 512 KB dual-bank code flash, 8 KB data flash, 256 KB SRAM with ECC/parity, integrated Ethernet MAC, USB 2.0 Full-Speed, CAN ×2, QSPI/OSPI, and Secure Crypto Engine (SCE9) with TrustZone for secure embedded applications in industrial gateways and connected edge devices.
For engineers reviewing the R7FA6M4AD3CFM#BA5 datasheet, R7FA6M4AD3CFM#BA5 pinout, R7FA6M4AD3CFM#BA5 application, or R7FA6M4AD3CFM#BA5 equivalent, key selection considerations include its 64-pin LQFP package, -40°C to +105°C temperature grade, 2.7–3.6 V supply, 109 I/O pins (9 with 5-V tolerance), and support for real-time deterministic communication via ETHERC, CAN, and USBFS.
Technical Context
The R7FA6M4AD3CFM#BA5 implements Armv8-M architecture with TrustZone security extension, enabling hardware-isolated secure and non-secure execution environments. It integrates SCE9 for AES/RSA/ECC/SHA256 acceleration, tamper detection, and lifecycle management - all coordinated with peripheral-level secure attribution.
Its system architecture includes dual DMA controllers (DMAC ×8 and DTC), Event Link Controller (ELC) for CPU-free peripheral chaining, and multiple clock domains (MOSC/SOSC/HOCO/PLL) with Clock Accuracy Measurement (CAC) for timing-critical applications like industrial Ethernet and motor control.
