Overview
R7FA4M2AC3CFM#AA0 from Renesas is a 32-bit Arm Cortex-M33 microcontroller operating at up to 100 MHz, featuring 384 KB code flash, 8 KB data flash, and 128 KB SRAM with parity/ECC. It integrates USB 2.0 Full-Speed, SDHI, Quad SPI, dual 12-bit DACs, 12-bit ADC (22-channel), CAN, TrustZone security, and SCE9 crypto engine. Designed for industrial HMI and secure edge-node applications requiring real-time control and tamper-resistant firmware.
For engineers reviewing the R7FA4M2AC3CFM#AA0 datasheet, R7FA4M2AC3CFM#AA0 pinout, R7FA4M2AC3CFM#AA0 application, or R7FA4M2AC3CFM#AA0 equivalent, this page delivers verified specifications, package mapping, functional pin roles, security architecture details, and validated alternative MCUs for scalable design migration.
Technical Context
The R7FA4M2AC3CFM#AA0 implements Armv8-M with TrustZone, enabling hardware-isolated secure and non-secure execution environments. Its Secure Crypto Engine 9 accelerates AES, RSA, ECC, DSA, SHA224/SHA256, and GHASH with a 128-bit unique ID and tamper detection support.
It features dual-domain memory protection (8-region MPU_S and MPU_NS), two independent SysTick timers (secure/non-secure), and event-driven peripherals via ELC-enabling low-latency sensor-to-actuator response without CPU intervention in motor control or touch HMI systems.

The R7FA4M2AC3CFM#AA0 includes a 12-bit successive approximation ADC (ADC12) with up to 22 input channels across its 64-pin LQFP package. Channel selection includes external analog inputs (ANmn), internal sources (temperature sensor, reference voltage), and flexible trigger options (software, timer, or external pin). The R7FA4M2AC3CFM#AA0's ADC12 achieves 1.0 LSB INL and supports scan mode with automatic channel sequencing for efficient multi-sensor acquisition.
Is the R7FA4M2AC3CFM#AA0 pin-compatible with other RA4M2 variants?
Yes, the R7FA4M2AC3CFM#AA0 shares identical pinout and electrical characteristics with other 64-pin RA4M2 variants-including R7FA4M2AD3CFM#AA0 and R7FA4M2AB3CFM#AA0-within the same PLQP0064KB-C package. All share the same I/O count (43), 5-V tolerant pins (9), and peripheral pin mappings (e.g., USB_DP/USB_DM, CTXn/CRXn, QSPCLK/QIO0–QIO3), enabling drop-in flash-size upgrades without PCB revision.
