Product details
Overview
R7FA6M4AD3CFP#HA0 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 512 KB code flash, 8 KB data flash, and 256 KB SRAM with ECC/parity. It integrates Ethernet MAC, USB 2.0 Full-Speed, dual CAN, QSPI/OSPI, SDHI, and Secure Crypto Engine (SCE9) with TrustZone for industrial edge gateways and secure IoT endpoints.
For engineers reviewing the R7FA6M4AD3CFP#HA0 datasheet, R7FA6M4AD3CFP#HA0 pinout, R7FA6M4AD3CFP#HA0 application, or R7FA6M4AD3CFP#HA0 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, real-world use cases in secure industrial connectivity, and validated alternative options for migration or sourcing flexibility.
Technical Context
The R7FA6M4AD3CFP#HA0 implements Armv8-M architecture with dual MPU instances (Secure/Non-secure), CoreSight ETM-M33 trace, and dual-bank flash supporting background SWAP operations. Its system-level security combines SCE9 cryptographic accelerators (AES/RSA/ECC/SHA256) with TrustZone-enforced memory region partitioning across flash, SRAM, and peripherals.
Connectivity includes IEEE 802.3-compliant ETHERC with integrated EDMAC, USBFS with internal transceiver and 10-pipe buffer, dual CAN 2.0B controllers requiring external transceivers, and QSPI/OSPI interfaces for external OctaFlash and serial ROMs - all accessible via dedicated bus areas (EQBIU/EOBIU) without CPU intervention.
