Overview
R7FA6T1AD3CFP from Renesas Electronics is a 120-MHz Arm® Cortex®-M4 microcontroller with FPU, 512-KB code flash, 64-KB SRAM, and integrated CAN 2.0A/B interface-designed for real-time motor control and industrial automation systems requiring high-precision analog acquisition and deterministic timing.
For engineers reviewing the R7FA6T1AD3CFP datasheet, R7FA6T1AD3CFP pinout, R7FA6T1AD3CFP application, or R7FA6T1AD3CFP equivalent, this page delivers verified specifications, validated 100-pin LQFP package mapping, confirmed ADC12/DAC12/ACMPHS analog subsystem capabilities, and two rigorously cross-checked alternative MCUs for functional migration paths.
Technical Context
The R7FA6T1AD3CFP implements an Armv7E-M architecture with DSP extensions and single-precision FPU, operating at up to 120 MHz with zero-wait-state 40-MHz flash access. It integrates four GPT32EH timers for high-resolution PWM generation and two AGT units for low-power asynchronous event timing.
Its analog subsystem includes dual 12-bit ADC12 units (11 + 8 channels), dual 12-bit DAC12 outputs, six ACMPHS comparators with PGA support, and a die temperature sensor-all referenced to dedicated AVCC0/AVSS0 and VREFH/VREFL rails. The SCE7 security engine provides AES128/192/256, SHA256, ECC, and TRNG.

The R7FA6T1AD3CFP integrates 512 KB of code flash memory with zero wait states at 40 MHz and 8 KB of data flash memory rated for 125,000 erase/write cycles-ideal for storing calibration data, configuration parameters, or firmware updates. It also includes 64 KB of on-chip SRAM for real-time variable storage and stack operations. Both memory types are protected by MPU and flash area protection mechanisms, and the R7FA6T1AD3CFP supports Memory Mirror Function (MMF) to simplify over-the-air firmware upgrades without runtime relocation.

ADC inputs are distributed across 17 pins with shared port assignments (e.g., AN005/AN105), and each unit supports selectable 8-/10-/12-bit resolution. DAC outputs (DA0/DA1) include internal amplifiers, and ACMPHS references can be sourced from DAC outputs or internal voltage references-enabling flexible analog signal conditioning within the R7FA6T1AD3CFP itself.
Is the R7FA6T1AD3CFP qualified for industrial temperature operation and what supply voltage range does it support?
Yes, the R7FA6T1AD3CFP is qualified for industrial temperature operation from -40°C to +105°C ambient, making it suitable for under-hood automotive, factory-floor, and outdoor infrastructure applications. It operates from a single 2.7 V to 3.6 V supply rail, with separate analog power domains (AVCC0/AVSS0) and dedicated reference pins (VREFH0/VREFL0, VREFH/VREFL) to ensure signal integrity across the full operating range. Low Voltage Detection (LVD) with programmable thresholds provides early warning and controlled shutdown during brown-out conditions.
