Product details
Overview
R7FA6M3AH3CFP#BA0 from Renesas Electronics is a high-performance 32-bit Arm Cortex-M4 microcontroller with FPU, operating at up to 120 MHz, featuring 2-MB code flash, 640-KB SRAM, dual CAN, IEEE 1588 Ethernet MAC (ETHERC), USB 2.0 High-Speed and Full-Speed, QSPI, SDHI, GLCDC, DRW, CTSU, and SCE7 cryptographic engine - deployed in industrial HMIs, networked gateways, and secure edge controllers.
For engineers reviewing the R7FA6M3AH3CFP#BA0 datasheet, R7FA6M3AH3CFP#BA0 pinout, R7FA6M3AH3CFP#BA0 application, or R7FA6M3AH3CFP#BA0 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-CAN bus redundancy, on-chip graphics acceleration (GLCDC + DRW), hardware AES-256/SHA-256 support, and 100-pin LQFP packaging for space-constrained industrial designs.
Technical Context
The R7FA6M3AH3CFP#BA0 implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time control and signal processing. Its memory subsystem includes ECC-protected SRAM (first 32 KB), 64-KB data flash with 125,000 erase/write cycles, and Memory Mirror Function (MMF) enabling flexible firmware load/link address decoupling.
System-level integration is enabled by the Event Link Controller (ELC), which routes peripheral events (e.g., timer overflows, ADC completions) directly to DMA or other modules without CPU intervention. Safety is reinforced via independent watchdog (IWDT), CAC clock accuracy monitoring, SRAM parity/ECC detection, and register write protection - all aligned with IEC 61508 SIL2-ready design practices.
