Product details
Overview
R7FA6M3AF3CFB#AA0 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/Full-Speed, QSPI, SDHI, GLCDC, DRW, CTSU, and SCE7 cryptographic engine - deployed in industrial HMI gateways requiring real-time control, secure connectivity, and graphics rendering.
For engineers reviewing the R7FA6M3AF3CFB#AA0 datasheet, R7FA6M3AF3CFB#AA0 pinout, R7FA6M3AF3CFB#AA0 application, or R7FA6M3AF3CFB#AA0 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-CAN bus isolation capability, on-chip graphics acceleration for WVGA+ displays, integrated TRNG and AES-256 security, and 144-pin LQFP package compatibility with industrial temperature range (−40°C to +105°C).
Technical Context
The R7FA6M3AF3CFB#AA0 implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time execution across multiple clock domains including MOSC (8–24 MHz), SOSC (32.768 kHz), and HOCO (16/18/20 MHz). Its memory subsystem includes ECC-protected SRAM (first 32 KB), MMF-enabled flash remapping, and 64-KB data flash rated for 125,000 erase/write cycles.
Peripherals are orchestrated via Event Link Controller (ELC) for CPU-free inter-module triggering, while safety is enforced by dual watchdogs (WDT/IWDT), CAC-based clock monitoring, SRAM parity/ECC error detection, and MPU-configurable memory protection across eight regions. The device integrates dedicated hardware accelerators: DRW for antialiased rasterization, JPEG codec for baseline compression/decompression, and SCE7 for AES-256/SHA256/RSA signing.
