Product details
Overview
R7FA4M2AB3CFP 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, CAN, SDHI, QSPI, dual 12-bit DACs, 12-bit ADC (22-channel), CTSU, and Secure Crypto Engine 9 with TrustZone for secure embedded control in industrial HMI and connected edge devices.
For engineers reviewing the R7FA4M2AB3CFP datasheet, R7FA4M2AB3CFP pinout, R7FA4M2AB3CFP application, or R7FA4M2AB3CFP equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +105°C operation, 2.7–3.6 V supply, dual DAC support, tamper-detect I/O, and hardware-accelerated AES/RSA/SHA256 for firmware integrity and secure boot.
Technical Context
The R7FA4M2AB3CFP implements Armv8-M with TrustZone, enabling secure/non-secure execution environments with separate MPU regions for code flash (up to 3), data flash (up to 2), and SRAM (up to 3). It features dual Systick timers (Secure/Non-secure) and CoreSight ETM-M33 for trace-enabled debugging.
Its system architecture integrates event-driven peripherals via ELC, DMA offload via 8-channel DMAC and DTC, and low-power operation with six AGT timers, RTC with VBATT backup, and multiple clock sources including HOCO/MOCO/LOCO with trim. The SCE9 engine provides dedicated accelerators for AES-128/256, RSA-2048/4096, ECC-P256/P384, and SHA224/256.
