Product details
Overview
R7FA6M2AF3CFP#BA0 from Renesas is a 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, USB 2.0 Full-Speed, and CTSU - deployed in industrial gateways requiring real-time control, secure connectivity, and capacitive HMI.
For engineers reviewing the R7FA6M2AF3CFP#BA0 datasheet, R7FA6M2AF3CFP#BA0 pinout, R7FA6M2AF3CFP#BA0 application, or R7FA6M2AF3CFP#BA0 equivalent, key selection considerations include its 100-pin LQFP package, -40°C to +105°C operation, dual CAN 2.0B support, integrated SCE7 crypto engine, and SDHI/QSPI interfaces for secure firmware updates and external memory expansion.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling deterministic real-time signal processing. It integrates dual independent watchdogs (WDT/IWDT), ECC on 32 KB of SRAM, and MPU with 8 regions for memory safety in functional-safety-critical systems.
The RA6M2 group uses a modular peripheral architecture: ETHERC links directly to EDMAC for zero-CPU packet handling; ELC enables hardware-triggered timer-to-peripheral event chaining; and CTSU supports up to 18 self-capacitive touch channels without external components - all coordinated via NVIC and DTC/DMAC for low-latency deterministic response.
