Product details
Overview
R7FA6M2AD2CLK#AC0 from Renesas Electronics is a 32-bit Arm Cortex-M4 microcontroller with FPU, operating at up to 120 MHz, featuring 512 KB code flash, 384 KB SRAM, dual CAN, Ethernet MAC, USB 2.0 Full-Speed, and CTSU for industrial HMI applications.
For engineers reviewing the R7FA6M2AD2CLK#AC0 datasheet, R7FA6M2AD2CLK#AC0 pinout, R7FA6M2AD2CLK#AC0 application, or R7FA6M2AD2CLK#AC0 equivalent, key selection criteria include its -40°C to +85°C temperature grade, 145-pin LGA package, integrated security engine (SCE7), dual 12-bit ADC units with 20 total analog inputs, and support for SDHI, QSPI, and real-time clock with battery backup.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling deterministic signal processing in motor control and audio applications. It integrates dual 12-bit ADCs (ADC12) with 3 sample-and-hold circuits per unit, supporting simultaneous sampling across up to 20 analog input channels.
The RA6M2 group uses a modular peripheral architecture with Event Link Controller (ELC) enabling hardware-triggered, CPU-free interactions between modules - e.g., ADC conversion completion directly triggering DMA transfer or GPT timer capture. Its SCE7 crypto engine supports AES128/192/256, SHA256, ECC, and TRNG for secure boot and firmware updates.
Key Specifications
