Product details
Overview
R7FA4M2AB3CFL#AA0 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, and TrustZone-enabled Secure Crypto Engine (SCE9) for AES/RSA/ECC/SHA256 - deployed in industrial HMI, secure gateway, and motor control edge nodes.
For engineers reviewing the R7FA4M2AB3CFL#AA0 datasheet, R7FA4M2AB3CFL#AA0 pinout, R7FA4M2AB3CFL#AA0 application, or R7FA4M2AB3CFL#AA0 equivalent, this page delivers verified package mapping (48-pin LQFP), validated peripheral integration (CAN, SSIE, CTSU), exact memory partitioning, and real-world selection guidance against comparable RA-series MCUs.
Technical Context
The R7FA4M2AB3CFL#AA0 implements Armv8-M with TrustZone, enabling hardware-isolated secure/non-secure worlds - each with dedicated SysTick timers, MPU regions (8 per world), and peripheral security attribution. Its SCE9 accelerator offloads AES-128/256, RSA-2048, ECC-P256, and SHA256 operations while supporting tamper detection via three dedicated pins and secure key injection.
System-level timing integrates PLL + HOCO/MOCO/LOCO oscillators with Clock Accuracy Measurement (CAC), while power management includes Deep Software Standby mode with RTC/VBATT retention, AGT timers for wake-up, and ELC-driven autonomous peripheral chaining - eliminating CPU intervention for sensor-to-memory transfers.
