Product details
Overview
R7FA6M4AD3CFM#BA0 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 support. It integrates Ethernet MAC, USB 2.0 Full-Speed, dual CAN, QSPI/OSPI, SDHI, and a Secure Crypto Engine (SCE9) with AES/RSA/ECC/SHA256 for industrial edge gateways requiring secure connectivity and real-time control.
For engineers reviewing the R7FA6M4AD3CFM#BA0 datasheet, R7FA6M4AD3CFM#BA0 pinout, R7FA6M4AD3CFM#BA0 application, or R7FA6M4AD3CFM#BA0 equivalent, key selection criteria include its -40°C to +105°C operation, 64-pin LQFP package, dual-bank flash architecture, TrustZone-enabled secure boot, and hardware-accelerated cryptography for IoT node authentication and firmware integrity verification.
Technical Context
The R7FA6M4AD3CFM#BA0 implements Armv8-M with TrustZone, enabling strict isolation between secure and non-secure firmware execution domains. Its memory subsystem includes dual-bank flash supporting background programming and SWAP operations, plus 256 KB SRAM with configurable ECC or parity protection per region.
Connectivity is centered on deterministic real-time interfaces: two ISO 11898-1 CAN controllers with 32 mailboxes each, an IEEE 802.3-compliant Ethernet MAC with integrated EDMAC DMA, and USBFS supporting host/device roles with internal transceiver - all accessible without CPU intervention via ELC event linking and DMAC/DTC data movers.

These features enable authenticated boot, encrypted firmware storage, and runtime integrity checking - all implemented without software-only reliance in the R7FA6M4AD3CFM#BA0.
What package type and pin count does the R7FA6M4AD3CFM#BA0 use?
The R7FA6M4AD3CFM#BA0 uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch. It provides 41 general-purpose I/O pins, 9 of which are 5-V tolerant, plus dedicated power, clock, reset, debug, and peripheral interface signals. This package is optimized for ease of assembly and thermal performance in industrial control modules.
Can the R7FA6M4AD3CFM#BA0 interface directly with an Ethernet PHY?
Yes, the R7FA6M4AD3CFM#BA0 includes an IEEE 802.3-compliant Ethernet MAC supporting RMII interface. It connects directly to standard RMII PHYs such as the LAN8720A or DP83848 without external glue logic. The integrated EDMAC enables zero-copy packet transfers via DMA, and the ELC allows autonomous timestamping of received frames - all fully supported in the R7FA6M4AD3CFM#BA0's hardware design.
