Product details
Overview
R7FA4M3AE3CFP#BA0 from Renesas is a 100 MHz Arm Cortex-M33 microcontroller with 768 KB code flash, 8 KB data flash, and 128 KB SRAM (with ECC), targeting secure industrial HMI and connected edge nodes requiring USB FS, SDHI, dual CAN, and capacitive touch. It integrates Secure Crypto Engine 9, TrustZone, and CTSU for tamper-resistant UI and firmware integrity.
For engineers reviewing the R7FA4M3AE3CFP#BA0 datasheet, R7FA4M3AE3CFP#BA0 pinout, R7FA4M3AE3CFP#BA0 application, or R7FA4M3AE3CFP#BA0 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +105°C operation, dual CAN 2.0B support, QSPI interface for external memory, and hardware-accelerated AES/RSA/SHA256 for secure boot and OTA updates.
Technical Context
The R7FA4M3AE3CFP#BA0 implements Armv8-M with TrustZone, enabling secure/non-secure world isolation across flash, SRAM, and peripherals - up to three secure regions in code flash and two in data flash. Its dual-core timer architecture includes four 32-bit GPTs for motor control and six low-power AGTs for event-driven wake-up.
Connectivity is segmented into high-speed (USBFS, SDHI, QSPI), robust industrial (dual CAN, SCI ×6), and audio-ready (SSIE with 50 MHz clock) domains. Analog subsystem features two independent 12-bit ADCs (5 Msps interleaved), two DACs, and on-die temperature sensor routed to ADC inputs.
