For engineers reviewing the R7FA6M5BG3CFB#AA0 datasheet, R7FA6M5BG3CFB#AA0 pinout, R7FA6M5BG3CFB#AA0 application, or R7FA6M5BG3CFB#AA0 equivalent, key selection considerations include its -40°C to +105°C operation, 144-pin LQFP package, dual-bank flash for safe firmware updates, hardware-accelerated AES/RSA/ECC, and support for RMII Ethernet and SDHI host interfaces.

Technical Context

The R7FA6M5BG3CFB#AA0 implements Armv8-M with TrustZone, enabling secure and non-secure execution environments managed by separate MPUs (8 regions each). Its memory subsystem includes dual-bank flash supporting background programming and SWAP operations, critical for over-the-air (OTA) firmware updates without system interruption.

Connectivity is centered on deterministic real-time I/O: two CAN FD controllers (16 TX/RX buffers each), Ethernet MAC with RMII interface, USB 2.0 High-Speed device/host, and dual high-speed serial interfaces (QSPI and OSPI) for external XIP-capable memory. Analog integration includes dual 12-bit ADCs (5 Msps interleaved), dual DACs, and temperature sensor with dedicated ADC channel.

FAQ

What is the maximum operating frequency of the R7FA6M5BG3CFB#AA0?

The R7FA6M5BG3CFB#AA0 operates at a maximum frequency of 200 MHz using the Arm Cortex-M33 core. This speed is achieved with the PLL clock source and requires proper decoupling and thermal management per the datasheet's layout guidelines. The core supports dynamic voltage and frequency scaling (DVFS) to reduce power during low-load conditions while maintaining real-time determinism.

Does the R7FA6M5BG3CFB#AA0 support CAN FD, and how many channels are available?

Yes, the R7FA6M5BG3CFB#AA0 supports CAN with Flexible Data-rate (CAN FD) on two independent channels. Each channel provides 16 transmit and 16 receive buffers, complies with ISO 11898-1, and supports bit rates up to 5 Mbps in FD mode. This enables high-throughput diagnostics and control messaging in automotive and industrial networks without requiring external CAN FD controllers.

What security features does the R7FA6M5BG3CFB#AA0 integrate beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5BG3CFB#AA0 integrates the Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES-128/256, RSA-2048/3072, ECC-256/384, and SHA-224/256. It also includes tamper detection pins, power analysis resistance, unique 128-bit ID, and device lifecycle management - all coordinated with TrustZone to form a certified secure element foundation for secure boot and key provisioning.

Which package type and pin count does the R7FA6M5BG3CFB#AA0 use?

The R7FA6M5BG3CFB#AA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 109 general-purpose I/O pins, 21 of which are 5-V tolerant, and supports -40°C to +105°C operation. This package is optimized for manual assembly, optical inspection, and thermal dissipation in space-constrained industrial PCBs.

Does the R7FA6M5BG3CFB#AA0 include Ethernet capability, and what interface does it support?

Yes, the R7FA6M5BG3CFB#AA0 includes a single-channel Ethernet MAC (ETHERC) compliant with IEEE 802.3, connected to the Ethernet DMA Controller (EDMAC) for zero-copy packet transfers. It supports RMII interface only - requiring an external PHY with 50 MHz reference clock - and does not support MII or GMII. This enables compact, low-latency 10/100 Mbps connectivity for industrial Ethernet protocols.
