Product details
Overview
R7FA6M1AD3CNB#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, 256 KB SRAM, dual 12-bit ADCs with sample-and-hold, two 12-bit DACs, and integrated Capacitive Touch Sensing Unit (CTSU). It targets industrial HMI, motor control, and secure embedded systems requiring USBFS, dual CAN, SDHI, QSPI, and hardware crypto acceleration.
For engineers reviewing the R7FA6M1AD3CNB#AC0 datasheet, R7FA6M1AD3CNB#AC0 pinout, R7FA6M1AD3CNB#AC0 application, or R7FA6M1AD3CNB#AC0 equivalent, key selection criteria include its 64-pin QFN package (8 mm × 8 mm, 0.4 mm pitch), -40°C to +105°C temperature grade, 2.7–3.6 V operation, dual CAN 2.0B support, and SCE7 security engine with AES-256, TRNG, and SHA256.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling real-time signal processing in motor control and audio applications. Its memory subsystem includes ECC-protected SRAM (32 KB), parity-checked SRAM (224 KB), and 8 KB data flash rated for 125,000 erase/write cycles.
The peripheral set is optimized for system integration: dual CAN modules support redundant fieldbus communication; QSPI and dual SDHI enable high-bandwidth external storage; SSIE and SRC provide full-duplex I2S audio handling with sampling rate conversion; and ELC enables zero-CPU-latency peripheral chaining for deterministic timing-critical tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6M1AD3CFM | Same RA6M1 core, identical peripherals, but in 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) - larger footprint, easier hand-soldering. | LQFP variant preferred for prototyping or low-volume production where reflow capability is limited. | Select R7FA6M1AD3CFM when board assembly uses through-hole or manual soldering; QFN (R7FA6M1AD3CNB#AC0) suits high-density automated production. |
| R7FA6M2AD3CFM | RA6M2 series successor: same package, +128 KB SRAM (384 KB total), +1x SCI, +1x I2C, enhanced SCE7 with RSA-3072, but no CTSU. | Preferred for next-gen designs needing more RAM or stronger crypto, but unsuitable where capacitive touch is required. | Choose R7FA6M2AD3CFM only if CTSU is not needed and additional memory/crypto is critical; R7FA6M1AD3CNB#AC0 remains optimal for touch-enabled cost-sensitive designs. |
Compared with R7FA6M1AD3CFM, R7FA6M1AD3CNB#AC0 offers identical functionality in a smaller, thermally superior QFN package ideal for compact industrial modules.
