Product details
Overview
R7FA6M1AD3CFP from Renesas Electronics is a 32-bit Arm Cortex-M4 microcontroller with FPU, operating at up to 120 MHz, featuring 512 KB code flash, 256 KB SRAM, dual 12-bit ADCs with sample-and-hold, two 12-bit DACs, six high-speed analog comparators, capacitive touch sensing (CTSU), USB 2.0 Full-Speed with on-chip transceiver, dual CAN 2.0A/B controllers, and SDHI for industrial HMI and motor control applications.
For engineers reviewing the R7FA6M1AD3CFP datasheet, R7FA6M1AD3CFP pinout, R7FA6M1AD3CFP application, or R7FA6M1AD3CFP equivalent, this MCU delivers deterministic real-time performance in extended temperature (-40°C to +105°C), supports secure boot via SCE7 crypto engine (AES-128/192/256, SHA256, TRNG), and integrates ELC for hardware-triggered peripheral chaining without CPU intervention.
Technical Context
The R7FA6M1AD3CFP implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling efficient signal processing in motor control and audio applications. It features dual independent 12-bit ADC units (ADC12) with 3-channel sample-and-hold per unit, supporting up to 17 analog inputs and selectable 8/10/12-bit resolution.
Its system-level timing infrastructure includes four GPT32EH timers (enhanced high-resolution PWM), two AGT low-power asynchronous timers, RTC with calendar mode, and CAC for clock accuracy monitoring. The Event Link Controller (ELC) enables direct peripheral-to-peripheral triggering-e.g., ADC conversion completion can directly start DMA transfer or trigger GPT capture-reducing latency and CPU load.
