Product details
Overview
R7FA6M2AF3CFP#AA5 from Renesas Electronics is a 120-MHz Arm Cortex-M4 microcontroller with FPU, 1-MB code flash, 384-KB SRAM, dual CAN, Ethernet MAC, USB 2.0 Full-Speed, QSPI, SDHI×2, CTSU, and SCE7 crypto engine - designed for industrial IoT gateways requiring real-time control, secure connectivity, and analog sensing at -40°C to +105°C.
For engineers reviewing the R7FA6M2AF3CFP#AA5 datasheet, R7FA6M2AF3CFP#AA5 pinout, R7FA6M2AF3CFP#AA5 application, or R7FA6M2AF3CFP#AA5 equivalent, key selection considerations include its 100-pin LQFP package, dual 12-bit ADC units (20-channel total), 2× DAC12, 6× ACMPHS, and integrated ETHERC+EDMAC for zero-CPU-frame-transfer networking.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time execution up to 120 MHz. Its memory subsystem includes ECC-protected SRAM (32 KB), parity-checked SRAM (352 KB), 32-KB data flash rated for 125,000 erase/write cycles, and Memory Mirror Function (MMF) enabling flexible firmware load/link address separation.
The peripheral set integrates hardware-accelerated security (AES128/192/256, SHA256, TRNG, RSA/ECC), safety features (IWDT, CAC, CRC, DOC, MPU), and mixed-signal capability: two independent 12-bit ADCs with sample-and-hold, dual DAC12 outputs, six high-speed comparators, and temperature sensor output routed to ADC inputs.
