For engineers reviewing the R7FA6M5BG2CBG datasheet, R7FA6M5BG2CBG pinout, R7FA6M5BG2CBG application, or R7FA6M5BG2CBG equivalent, key selection criteria include its -40°C to +85°C temperature grade, 176-pin FBGA package (PLBG0176GF-A), 2 CAN FD channels, Ethernet MAC with RMII support, and SCE9-accelerated AES/RSA/SHA256 for firmware signing and secure boot.

Technical Context

The R7FA6M5BG2CBG implements Armv8-M with TrustZone, enabling hardware-isolated secure and non-secure execution environments. Its memory subsystem includes dual-bank flash supporting background operation and SWAP, plus 512 KB SRAM partitioned into 448 KB parity-protected and 64 KB ECC-protected regions.

Connectivity is centered on two independent CAN FD controllers (16 TX/RX buffers each), an RMII-capable Ethernet MAC/DMA controller, USB 2.0 High-Speed and Full-Speed modules with internal transceivers, and parallel QSPI/OSPI interfaces for external XIP-capable flash. The SCE9 engine offloads cryptographic operations including AES-128/256, RSA-2048/4096, ECC-P256/P384, and SHA224/256.

FAQ

What is the maximum operating frequency and core architecture of the R7FA6M5BG2CBG?

The R7FA6M5BG2CBG features an Arm Cortex-M33 core running at a maximum frequency of 200 MHz. It implements the Armv8-M architecture with Security Extension (TrustZone), PMSAv8 Memory Protection Unit (8 secure + 8 non-secure regions), and dual Systick timers for secure and non-secure contexts. This architecture enables hardware-enforced isolation between trusted and untrusted software domains - a foundational capability used by the R7FA6M5BG2CBG in secure boot and firmware update implementations.

Does the R7FA6M5BG2CBG support CAN FD, and how many channels are available?

Yes, the R7FA6M5BG2CBG integrates two independent CAN FD controllers compliant with ISO 11898-1, each supporting classical CAN and CAN FD frames up to 5 Mbps. Each channel provides 16 dedicated transmit buffers and 16 receive buffers, enabling concurrent handling of high-bandwidth vehicle diagnostics and industrial control traffic. This dual-CAN FD capability is confirmed in the R7FA6M5BG2CBG datasheet section 1.4 (Function Comparison) and is physically implemented on dedicated differential pin pairs (CANFD0_TX/RX and CANFD1_TX/RX) in its 176-pin FBGA package.

What security features does the R7FA6M5BG2CBG include beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5BG2CBG includes the Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES-128/256, RSA-2048/4096, ECC-P256/P384, and SHA224/256; tamper detection via three dedicated pins; 128-bit unique device ID; secure key management with protected storage; and lifecycle management for secure provisioning and decommissioning. These features are documented in the R7FA6M5BG2CBG datasheet sections 1.1 (Function Outline) and Table 1.14 (Function Comparison), and collectively enable certified secure boot, firmware signing, and runtime attestation - all executed without CPU intervention.

What is the package type and pin count of the R7FA6M5BG2CBG?

The R7FA6M5BG2CBG uses a 176-pin Fine-Pitch Ball Grid Array (FBGA) package with part code PLBG0176GF-A, measuring 7 mm × 7 mm with 0.5 mm pitch and Sn (Tin) terminal finish. This package provides 132 general-purpose I/O pins, 17 of which are 5-V tolerant, along with dedicated power, clock, reset, debug, and peripheral interface balls. The package type is explicitly defined in the R7FA6M5BG2CBG part numbering scheme (Figure 1.2) and verified in Table 1.13 (Product List) of the official datasheet R01DS0366EJ0150.

Does the R7FA6M5BG2CBG support Ethernet, and what interface standard is implemented?

Yes, the R7FA6M5BG2CBG includes an IEEE 802.3-compliant Ethernet MAC controller (ETHERC) with integrated DMA support, specifically configured for Reduced Media Independent Interface (RMII). It supports 10/100 Mbps operation and connects directly to external PHYs via dedicated RMII pins (ETH_TXD0/1, ETH_RXD0/1, ETH_REF_CLK, ETH_CRS_DV, ETH_COL, ETH_MDC/MDIO). This implementation is confirmed in the R7FA6M5BG2CBG datasheet section 1.4 (Function Comparison) and block diagram (Figure 1.1), and enables low-latency, CPU-offloaded packet transmission and reception essential for industrial networking applications.
