Product details
Overview
R7FA4M3AE3CFP#AA0 from Renesas is a 100 MHz Arm Cortex-M33 microcontroller with 768 KB code flash, 8 KB data flash, 128 KB SRAM (with ECC), USB 2.0 Full-Speed, SDHI, Quad SPI, dual CAN, and integrated Secure Crypto Engine with TrustZone for secure embedded applications in industrial HMI and connected edge devices.
For engineers reviewing the R7FA4M3AE3CFP#AA0 datasheet, R7FA4M3AE3CFP#AA0 pinout, R7FA4M3AE3CFP#AA0 application, or R7FA4M3AE3CFP#AA0 equivalent, key selection criteria include operating temperature range (−40°C to +105°C), 100-pin LQFP package, dual 12-bit ADCs (5 Msps interleaved), CTSU for capacitive touch, and hardware-accelerated AES/RSA/ECC cryptography.
Technical Context
The R7FA4M3AE3CFP#AA0 implements Armv8-M architecture with TrustZone-enforced secure/non-secure worlds, supporting up to three secure regions in code flash and two in data flash. Its dual-core timer system includes four 32-bit GPT32 channels for motor control and six low-power AGT timers for event-driven wake-up.
Security is enforced via SCE9 crypto engine (AES-128/256, RSA-2048, ECC-P256, SHA-256) paired with tamper-detect pins and secure pin multiplexing. Analog subsystem integrates two independent 12-bit ADC units (12+10 channels total) with shared input pins and internal temperature sensor output routed to both units.

This architecture enables deterministic real-time performance with hardware-enforced security isolation.
Does the R7FA4M3AE3CFP#AA0 support USB host functionality, and what are its requirements?
Yes, the R7FA4M3AE3CFP#AA0 USB 2.0 Full-Speed module supports both host and device modes. In host mode, it supports low-speed and full-speed transfers per USB 2.0 specification, requires no external PHY (integrated transceiver), and provides up to 10 configurable pipes with 1.2 kB on-chip buffer memory. External components needed include standard USB series resistors and VBUS monitoring circuitry connected to the USB_VBUS pin.
How does the Secure Crypto Engine (SCE9) in the R7FA4M3AE3CFP#AA0 accelerate cryptographic operations?
The SCE9 in the R7FA4M3AE3CFP#AA0 provides hardware acceleration for AES-128/256 (ECB/CBC/CTR/GCM), RSA-2048/3072, ECC-P256/P384, and SHA-224/256 hash generation. It offloads compute-intensive operations from the CPU, reduces encryption latency by >10× versus software-only implementation, and includes dedicated key management with tamper-resistant storage. The engine integrates with TrustZone to enforce secure key access and prevent leakage during cryptographic processing.
What analog peripherals are integrated into the R7FA4M3AE3CFP#AA0, and how are they configured?
The R7FA4M3AE3CFP#AA0 integrates two independent 12-bit successive approximation ADC units (ADC12): Unit 0 supports up to 12 channels, Unit 1 up to 10 channels, with three shared pins (AN000/AN100, etc.) enabling synchronized sampling. It also includes two 12-bit DAC channels (DAC12), an on-die temperature sensor (TSN) whose output feeds both ADC units, and dedicated analog power rails (AVCC0/AVSS0) with separate reference pins (VREFH0/VREFL0, VREFH/VREFL) for flexible signal conditioning.
Is the R7FA4M3AE3CFP#AA0 pin-compatible with other RA4M3 group members, and what package options exist?
Yes, the R7FA4M3AE3CFP#AA0 is pin-compatible with other 100-pin LQFP variants in the RA4M3 family, including R7FA4M3AF3CFP#AA0 (1 MB flash) and R7FA4M3AD3CFP#AA0 (512 KB flash). All share identical PLQP0100KB-B footprint, I/O count (75), and pin functions. Other RA4M3 packages include 144-pin LQFP/BGA and 64-pin LQFP/BGA, but these are not pin-compatible due to differing pin counts and layouts.
