Product details
Overview
R7FA8M1AFECFB#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), dual CAN FD, Ethernet MAC, 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 R7FA8M1AFECFB#BA0 datasheet, R7FA8M1AFECFB#BA0 pinout, R7FA8M1AFECFB#BA0 application, or R7FA8M1AFECFB#BA0 equivalent, key selection considerations include its 144-pin LQFP package, -40°C to +125°C junction temperature rating, dual-bank flash support for seamless firmware updates, and verified compatibility with RA8M1 software ecosystem and FSP v4.x.
Technical Context
The R7FA8M1AFECFB#BA0 implements Armv8.1-M architecture with Helium™ M-profile Vector Extension (MVE-F) for accelerated signal processing, paired with dual 12-bit ADCs (25-channel total), two 12-bit DACs, and two high-speed analog comparators for closed-loop motor and sensor conditioning. Its memory subsystem includes 1 MB SRAM split into 128 KB TCM (ECC) and 896 KB user SRAM (512 KB parity, 384 KB ECC).
Connectivity is centered on deterministic real-time interfaces: two CAN FD controllers (4 Tx/16 Rx buffers each), IEEE 802.3-compliant Ethernet MAC with DMA, USB 2.0 HS/FS dual-role capability, dual SDHI supporting SDXC/eMMC 4.51, and Octal SPI compliant with JEDEC JESD251 Profile 1.0 for high-bandwidth external memory expansion.

FAQ
What is the maximum operating frequency of the R7FA8M1AFECFB#BA0?
The R7FA8M1AFECFB#BA0 operates at a maximum frequency of 480 MHz using its Arm Cortex-M85 core. This speed is achieved with PLL1 driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO), and is validated across the full −40°C to +125°C junction temperature range per the R01DS0417EJ0130 datasheet.
Does the R7FA8M1AFECFB#BA0 support dual-bank flash operation?
No-the R7FA8M1AFECFB#BA0 has 1 MB of code flash configured as a single bank. Dual-bank operation is only available on R7FA8M1AHECx variants (e.g., R7FA8M1AHECFB#BA0) with 2 MB flash. However, R7FA8M1AFECFB#BA0 still supports background programming and SWAP-like updates via software-managed sector reorganization.
Which security features are implemented in hardware on the R7FA8M1AFECFB#BA0?
The R7FA8M1AFECFB#BA0 integrates Renesas Secure IP (RSIP-E51A) with AES-128/256, RSA-2048/4096, ECC NIST P-256/P-384, SHA-256/384, and 128-bit true random number generation. It also includes Arm TrustZone®, secure debug lockdown, tamper-resistant pins, secure boot with immutable ROM FSBL, and decryption-on-the-fly (DOTF) for external flash.
Can the R7FA8M1AFECFB#BA0 directly interface with an Ethernet PHY without external components?
Yes-the R7FA8M1AFECFB#BA0 includes a fully compliant IEEE 802.3 Ethernet MAC with RMII/MII interface and integrated EDMAC. It requires only an external PHY (e.g., Microchip LAN8742A or Texas Instruments DP83848) and standard magnetics; no level shifters, resistors, or capacitors beyond PHY reference design are needed for basic 10/100 Mbps operation.
What is the pin count and package type of the R7FA8M1AFECFB#BA0?
The R7FA8M1AFECFB#BA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 106 general-purpose I/O pins, all 5-V tolerant, with configurable pull-up/down, open-drain, and switchable drive strength-validated per Renesas' RA8M1 pin list documentation.
