Product details
Overview
R7FA6M2AF3CFB#BA0 from Renesas is a high-performance 32-bit Arm Cortex-M4 microcontroller with FPU, operating at up to 120 MHz, featuring 1-MB code flash, 384-KB SRAM, dual CAN, Ethernet MAC (ETHERC), USB 2.0 Full-Speed, and CTSU for touch HMI - deployed in industrial gateways requiring real-time connectivity, secure firmware updates, and deterministic control.
For engineers reviewing the R7FA6M2AF3CFB#BA0 datasheet, R7FA6M2AF3CFB#BA0 pinout, R7FA6M2AF3CFB#BA0 application, or R7FA6M2AF3CFB#BA0 equivalent, key selection considerations include its -40°C to +105°C extended temperature rating, 144-pin LQFP package with 21 5-V-tolerant I/Os, dual SDHI support for redundant storage, and SCE7 cryptographic engine enabling TLS/HTTPS offload in edge node designs.
Technical Context
The R7FA6M2AF3CFB#BA0 implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time execution across safety-critical peripherals including dual watchdog timers (WDT/IWDT), ECC-protected SRAM (32 KB), and ADC self-diagnosis. Its memory subsystem integrates Flash Cache (FCACHE), Memory Mirror Function (MMF), and 32-KB data flash rated for 125,000 erase/write cycles.
Connectivity is orchestrated via dedicated hardware accelerators: ETHERC+EDMAC enables zero-CPU packet handling; QSPI and dual SDHI provide parallel nonvolatile storage interfaces; and ELC links 10 SCI, 3 I²C, 2 SPI, 2 CAN, SSIE, and USBFS events without CPU intervention - critical for low-latency sensor fusion and protocol bridging.
Key Specifications
