Product details
Overview
R7FA4M2AB3CFM#BA0 from Renesas is a 100 MHz Arm Cortex-M33 microcontroller with 256 KB code flash, 8 KB data flash, and 128 KB SRAM (with parity/ECC), integrated USB 2.0 Full-Speed, SDHI, QSPI, dual 12-bit DACs, 12-bit ADC (22-channel), CAN, and Secure Crypto Engine (AES/RSA/ECC/SHA256) for industrial HMI and secure edge node applications.
For engineers reviewing the R7FA4M2AB3CFM#BA0 datasheet, R7FA4M2AB3CFM#BA0 pinout, R7FA4M2AB3CFM#BA0 application, or R7FA4M2AB3CFM#BA0 equivalent, this page delivers verified technical context, package-specific pin mapping, security-aware feature value, real-world HMI/industrial use cases, and two validated alternative MCUs - all grounded in Renesas R01DS0367EJ0150 Rev.1.50.
Technical Context
The R7FA4M2AB3CFM#BA0 implements Armv8-M architecture with TrustZone-enabled secure/non-secure execution environments, dual Systick timers, and PMSAv8 MPU (8 regions each). Its clock system includes MOSC (8–24 MHz), SOSC (32.768 kHz), HOCO/MOCO/LOCO oscillators, and dual PLLs supporting precise frequency synthesis and clock accuracy measurement via CAC.
Peripheral integration centers on deterministic real-time control: GPT32×4 + GPT16×4 timers support BLDC motor PWM with Hall sensor inputs (GTIU/GTIV/GTIW) and complementary outputs (GTOUUP/GTOULO); AGT×6 enables low-power event timing; ELC links peripherals without CPU intervention; and DTC/DMAC×8 offload data movement from the core.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Arm Cortex-M33 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA4M2AD3CFM#BA0 | 512 KB code flash (vs. 256 KB), same 64-pin LQFP package, identical peripherals and security features. | Required when firmware image size exceeds 256 KB or future-proofing for feature-rich OTA updates is needed. | Select R7FA4M2AD3CFM#BA0 only if full 512 KB flash utilization is confirmed; otherwise R7FA4M2AB3CFM#BA0 offers optimal cost/performance balance. |
| STM32H743VI | Arm Cortex-M7 @ 480 MHz, 2 MB flash, no integrated TrustZone or SCE9; requires external crypto co-processor for equivalent security. | Suitable for compute-intensive DSP tasks but increases BOM cost and design complexity for secure boot and key management. | Choose STM32H743VI only when raw FPU/DSP throughput outweighs security integration benefits; R7FA4M2AB3CFM#BA0 delivers lower total system cost for secure industrial nodes. |
Compared with R7FA4M2AD3CFM#BA0, the R7FA4M2AB3CFM#BA0 saves flash cost without sacrificing peripheral capability or security; versus STM32H743VI, it integrates TrustZone and SCE9 to reduce external components, PCB area, and certification effort for IEC 62443 Level 1 systems.
