Product details
Overview
R7FA8M1AFECFP#BA0 from Renesas is a high-performance 32-bit Arm® Cortex®-M85 microcontroller operating at up to 480 MHz, featuring 1 MB code flash, 12 KB data flash, 1 MB SRAM (with ECC/parity), Ethernet MAC, dual CAN FD, USB 2.0 High-Speed, OSPI, and integrated Renesas Secure IP (RSIP-E51A) with TrustZone® for secure boot and decryption-on-the-fly. It targets industrial gateways requiring real-time connectivity, deterministic control, and hardware-enforced security.
For engineers reviewing the R7FA8M1AFECFP#BA0 datasheet, R7FA8M1AFECFP#BA0 pinout, R7FA8M1AFECFP#BA0 application, or R7FA8M1AFECFP#BA0 equivalent, key selection considerations include its 100-pin LQFP package, -40°C to +125°C junction temperature rating, dual-bank flash support for safe firmware updates, and full peripheral integration including ETHERC, CANFD × 2, and SSIE for audio edge processing - all critical for scalable, secure embedded designs.
Technical Context
The R7FA8M1AFECFP#BA0 implements Armv8.1-M architecture with Helium™ MVE for DSP-intensive workloads, paired with dual 8-region MPUs (Secure/Non-secure) and two independent SysTick timers. Its memory subsystem includes ECC-protected SRAM0 and parity-checked SRAM1, plus background SWAP operation enabling zero-downtime firmware upgrades.
Connectivity is built around concurrent high-speed interfaces: Ethernet MAC with DMA offload, USBHS/USBFS dual-role controllers, OSPI supporting xSPI JEDEC JESD251 Profile 1.0 (Octal SPI), and I3C for low-power sensor hubs. Security integrates RSIP-E51A accelerators (AES/RSA/ECC/HASH), tamper-resistant pins, and TrustZone®-enforced peripheral isolation.

FAQ
What is the maximum operating frequency of the R7FA8M1AFECFP#BA0?
The R7FA8M1AFECFP#BA0 operates at a maximum frequency of 480 MHz using its Arm Cortex-M85 core with Helium™ technology. This speed is achieved with PLL1P clock source and requires proper decoupling and thermal management per the datasheet's layout guidelines. The R7FA8M1AFECFP#BA0 maintains this frequency across its full -40°C to +125°C operating junction temperature range when powered within the specified 1.68–3.6 V VCC range.
Does the R7FA8M1AFECFP#BA0 support Ethernet connectivity?
Yes, the R7FA8M1AFECFP#BA0 integrates a single-channel IEEE 802.3-compliant Ethernet MAC controller (ETHERC) with dedicated DMA (EDMAC) for zero-copy packet handling. It requires an external PHY and supports MII/RMII interfaces via configurable pins. The R7FA8M1AFECFP#BA0 does not include a physical layer transceiver - that must be added externally per application requirements.
How does the R7FA8M1AFECFP#BA0 implement hardware security?
The R7FA8M1AFECFP#BA0 combines Arm TrustZone® for system-level memory and peripheral isolation with Renesas Secure IP (RSIP-E51A) for cryptographic acceleration. RSIP-E51A provides AES-128/256, RSA-2048/4096, ECC NIST P-256/P-384, SHA-256/384, and true random number generation. Tamper-resistant pins and secure boot with immutable ROM (FSBL) complete the root-of-trust architecture in the R7FA8M1AFECFP#BA0.
What package type and pin count does the R7FA8M1AFECFP#BA0 use?
The R7FA8M1AFECFP#BA0 uses a 100-pin LQFP package (PLQP0100KP-A), measuring 14 mm × 14 mm with 0.5 mm pitch. It provides 70 general-purpose I/O pins, including 5-V tolerant, open-drain, and pull-up configurable options. This package matches the footprint of other RA8M1 variants like R7FA8M1AHECFP#BA0, enabling scalable design reuse.
Can the R7FA8M1AFECFP#BA0 perform firmware updates without interrupting operation?
Yes, the R7FA8M1AFECFP#BA0 supports background SWAP operations and dual-bank flash architecture, allowing seamless firmware updates. While one bank executes code, the other receives and validates new firmware; the R7FA8M1AFECFP#BA0 then atomically switches banks with minimal latency. This capability is enabled by hardware-supported SWAP commands and verified in the R7FA8M1AFECFP#BA0's Flash Control Unit (FCU) documentation.
