Product details
Overview
R7FA6M3AF3CFP#AA0 from Renesas Electronics is a high-performance 32-bit Arm Cortex-M4 microcontroller with FPU, designed for industrial HMI, networked edge devices, and real-time control systems. It operates at up to 120 MHz, integrates 2 MB code flash, 640 KB SRAM, dual CAN, IEEE 1588 Ethernet MAC (ETHERC), USB 2.0 High-Speed/Full-Speed, and hardware-accelerated graphics (GLCDC + DRW) - enabling embedded GUIs with capacitive touch (CTSU) and JPEG decode.
For engineers reviewing the R7FA6M3AF3CFP#AA0 datasheet, R7FA6M3AF3CFP#AA0 pinout, R7FA6M3AF3CFP#AA0 application, or R7FA6M3AF3CFP#AA0 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +105°C industrial temperature rating, integrated security engine (SCE7), analog subsystem (ADC12/DAC12/ACMPHS/PGA), and support for deterministic real-time operation via ELC, AGT timers, and PTP synchronization.
Technical Context
The R7FA6M3AF3CFP#AA0 implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic floating-point math and signal processing. Its memory subsystem includes ECC-protected SRAM (first 32 KB), 64 KB data flash rated for 125,000 erase/write cycles, and Memory Mirror Function (MMF) for flexible firmware update deployment without address remapping.
Real-time system coordination is enabled by the Event Link Controller (ELC), which routes peripheral events (e.g., ADC conversion complete, timer overflow) directly to other modules like GPT or DMAC - eliminating CPU intervention. Safety is reinforced by independent watchdog (IWDT), CAC clock accuracy monitoring, SRAM parity/ECC error detection, and register write protection.
