R7FA6M4AE3CFP#HA0 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 768 KB dual-bank code flash with background SWAP, 8 KB data flash, 256 KB SRAM with parity/ECC, integrated Ethernet MAC, USB 2.0 Full-Speed, SDHI, QSPI/OSPI, dual CAN, and Secure Crypto Engine (SCE9) with TrustZone for secure IoT edge nodes.

For engineers reviewing the R7FA6M4AE3CFP#HA0 datasheet, R7FA6M4AE3CFP#HA0 pinout, R7FA6M4AE3CFP#HA0 application, or R7FA6M4AE3CFP#HA0 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, functional pin roles, security-aware peripheral integration, and real-world industrial connectivity use cases - all confirmed against Renesas R01DS0365EJ0160 Rev.1.60.

Technical Context

The R7FA6M4AE3CFP#HA0 implements Armv8-M architecture with TrustZone-enforced secure/non-secure execution environments, supporting dual-region MPU configuration (8 regions each) and isolated SysTick timers. Its memory subsystem includes dual-bank flash enabling live firmware updates without interruption and ECC-protected SRAM for safety-critical operation.

Connectivity is hardware-accelerated via dedicated peripherals: ETHERC/EDMAC for zero-CPU-load Ethernet frame handling, USBFS with internal transceiver and 10-pipe endpoint support, and two independent CAN 2.0B controllers with 32 configurable mailboxes - all accessible through deterministic event-driven routing via ELC and DMA-assisted data movement using DMAC (8-channel) and DTC.

FAQ

What is the maximum operating frequency of the R7FA6M4AE3CFP#HA0?

The R7FA6M4AE3CFP#HA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved with the PLL clock source and is fully supported across the −40°C to +105°C industrial temperature range. The R7FA6M4AE3CFP#HA0 maintains timing compliance under worst-case voltage (2.7 V) and temperature conditions as validated in Renesas characterization testing.

Does the R7FA6M4AE3CFP#HA0 include an integrated Ethernet PHY?

No, the R7FA6M4AE3CFP#HA0 integrates only the Ethernet MAC (ETHERC) and DMA controller (EDMAC), not a physical layer transceiver. It supports RMII interface and requires an external PHY such as the LAN8742A or KSZ8081RND for 10/100 Mbps operation. The R7FA6M4AE3CFP#HA0 provides all necessary timing signals, MDIO/MDC management interface, and packet buffering to interface directly with industry-standard PHYs.

How many CAN interfaces does the R7FA6M4AE3CFP#HA0 support?

The R7FA6M4AE3CFP#HA0 integrates two independent Controller Area Network (CAN) 2.0B modules, each supporting standard (11-bit) and extended (29-bit) identifiers, up to 32 configurable mailboxes, and FIFO/reception modes. Both CAN controllers require external transceivers (e.g., TJA1042T) for physical bus connection and are electrically isolated from the MCU core via TrustZone-peripheral attribution.

What security features are implemented in hardware on the R7FA6M4AE3CFP#HA0?

The R7FA6M4AE3CFP#HA0 implements Arm TrustZone for memory and peripheral isolation, Secure Crypto Engine 9 (SCE9) with AES-128/256, RSA-2048, ECC-256, SHA256, and GHASH acceleration, 128-bit unique ID, tamper detection pins, secure pin multiplexing, and device lifecycle management. These features are silicon-verified and documented in Renesas R01DS0365EJ0160 Rev.1.60 Section 1.12.

Is the R7FA6M4AE3CFP#HA0 pin-compatible with other RA6M4 variants?

Yes, the R7FA6M4AE3CFP#HA0 is pin-compatible with all RA6M4 devices in the 100-pin LQFP package (e.g., R7FA6M4AF3CFP#HA0, R7FA6M4AD3CFP#HA0), sharing identical pin count, pitch, mechanical footprint, and signal assignment. Firmware portability is ensured across flash variants due to Renesas' unified RA SDK and identical peripheral register maps.
