For engineers reviewing the R7FA6M5BG2CBG datasheet, R7FA6M5BG2CBG pinout, R7FA6M5BG2CBG application, or R7FA6M5BG2CBG equivalent, key selection criteria include its -40°C to +85°C operating range, 176-pin FBGA package, 2 CAN FD channels, hardware-accelerated AES/RSA/ECC, and support for RMII Ethernet PHY interface without external PHY clock buffering.

Technical Context

The R7FA6M5BG2CBG implements Armv8-M architecture with TrustZone security extension, enabling strict isolation between secure and non-secure firmware execution environments. It integrates dual-bank flash for background programming and SWAP operations, plus SCE9 crypto accelerators supporting AES-128/256, RSA-2048/4096, ECC secp256r1/secp384r1, and SHA-224/256.

Its system-level integration includes an Ethernet MAC compliant with IEEE 802.3 (RMII only), USB 2.0 High-Speed device/host controller with internal transceiver, two independent CAN FD controllers (ISO 11898-1), and a 10-channel SCI with UART, SPI, I²C, smart card, and Manchester modes - all accessible via configurable pin multiplexing on 132 GPIOs.

FAQ

What is the maximum operating frequency of the R7FA6M5BG2CBG?

The R7FA6M5BG2CBG operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the PLL clock source configured from the main oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The device maintains full peripheral functionality-including Ethernet MAC, USB HS, and dual CAN FD-at this frequency, with timing validated across the -40°C to +85°C temperature range specified for the R7FA6M5BG2CBG.

Does the R7FA6M5BG2CBG support TrustZone-based secure boot?

Yes, the R7FA6M5BG2CBG supports TrustZone-based secure boot through hardware-enforced isolation between secure and non-secure worlds. Its Arm Cortex-M33 core implements the Security Extension (Armv8-M), and the Memory Protection Unit (MPU) allows configuration of up to six secure flash regions. Secure boot flow is enabled via option byte settings that lock the initial vector table in secure flash, ensuring only authenticated, signed firmware executes before transitioning to non-secure application code - a capability confirmed in the R7FA6M5BG2CBG datasheet section 1.4 and R01DS0366EJ0150 Rev.1.50.

What package type and pin count does the R7FA6M5BG2CBG use?

The R7FA6M5BG2CBG uses a 176-pin Fine-Pitch Ball Grid Array (FBGA) package with a 7 mm × 7 mm body and 0.5 mm ball pitch (package code PLBG0176GF-A). It provides 132 general-purpose I/O pins, 17 of which are 5-V tolerant, along with dedicated power, clock, debug, and peripheral interface balls. This package is optimized for high-density PCB layouts and thermal performance in industrial applications where the R7FA6M5BG2CBG is deployed.

Can the R7FA6M5BG2CBG interface directly with an RMII Ethernet PHY?

Yes, the R7FA6M5BG2CBG includes an Ethernet MAC (ETHERC) fully compliant with IEEE 802.3 that supports RMII interface mode. It provides all required RMII signals - TX_EN, TXD[1:0], RXD[1:0], CRS_DV, REF_CLK - and supports 50 MHz REF_CLK input from the PHY. No external clock buffer or level shifter is needed, and the MAC connects directly to the Ethernet DMA Controller (EDMAC) for zero-CPU packet handling - a feature explicitly documented for the R7FA6M5BG2CBG in the RA6M5 datasheet section 1.4 and Figure 1.1 block diagram.

What cryptographic algorithms are accelerated by the Secure Crypto Engine (SCE9) in the R7FA6M5BG2CBG?

The Secure Crypto Engine 9 (SCE9) in the R7FA6M5BG2CBG accelerates symmetric algorithms (AES-128/192/256 in ECB/CBC/CTR/GCM modes), asymmetric algorithms (RSA-2048/3072/4096, ECC secp256r1/secp384r1, DSA), and hash functions (SHA-224/256, GHASH). It also provides true random number generation, tamper detection via dedicated pins, and secure key management with hardware-protected storage - all confirmed in the R7FA6M5BG2CBG datasheet section "Security and Encryption" and R01DS0366EJ0150 Rev.1.50 page 1.
