For engineers reviewing the R7FA6M5BF3CFP#BA0 datasheet, R7FA6M5BF3CFP#BA0 pinout, R7FA6M5BF3CFP#BA0 application, or R7FA6M5BF3CFP#BA0 equivalent, key selection considerations include its -40°C to +105°C operation, 100-pin LQFP package, CAN FD dual-channel capability, hardware-accelerated cryptography (AES/RSA/ECC/SHA256), and integrated Ethernet MAC with RMII interface.

Technical Context

The R7FA6M5BF3CFP#BA0 implements Armv8-M architecture with TrustZone security extension, supporting secure/non-secure execution states via dual MPU instances (8 regions each). Its memory subsystem includes dual-bank flash for background programming and SWAP operations, plus 1 KB standby SRAM with battery backup via VBATT.

Connectivity is centered on deterministic real-time interfaces: two independent CAN FD channels (16 TX/RX buffers each), USBHS/USBFS with internal transceivers and 10-pipe FIFO, ETHERC/EDMAC with RMII support, and QSPI/OSPI controllers for external XIP-capable memory. Analog integration includes dual 12-bit ADCs (5 Msps interleaved) and dual 12-bit DACs with on-die temperature sensor.

FAQ

What is the maximum operating frequency of the R7FA6M5BF3CFP#BA0?

The R7FA6M5BF3CFP#BA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the main clock oscillator (MOSC) or PLL configuration, and is fully supported across its -40°C to +105°C operating temperature range. The R7FA6M5BF3CFP#BA0 maintains timing compliance under worst-case voltage (2.7 V) and temperature conditions per its datasheet specifications.

Does the R7FA6M5BF3CFP#BA0 support CAN FD, and how many channels are available?

Yes, the R7FA6M5BF3CFP#BA0 supports CAN with Flexible Data-rate (CAN FD) on two independent channels, each with 16 transmit and 16 receive buffers. It complies with ISO 11898-1 and supports bit rates up to 5 Mbps in FD mode. This dual-channel capability is confirmed in the RA6M5 datasheet (R01DS0366EJ0150) and applies specifically to part numbers with "B" in the feature set position, including the R7FA6M5BF3CFP#BA0.

What package type and pin count does the R7FA6M5BF3CFP#BA0 use?

The R7FA6M5BF3CFP#BA0 uses a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch. It provides 75 general-purpose I/O pins, 14 of which are 5-V tolerant, along with dedicated power, clock, reset, and peripheral interface pins. This package is explicitly listed in Table 1.13 of the RA6M5 datasheet for the R7FA6M5BF3CFP variant.

What security features are integrated into the R7FA6M5BF3CFP#BA0?

The R7FA6M5BF3CFP#BA0 integrates Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES-128/256, RSA-2048/4096, ECC-256/384, and SHA224/256, plus Arm TrustZone for memory and peripheral isolation. It also includes tamper detection pins, secure key management, and device lifecycle controls. These features are documented in Section 1.1 and Table 1.14 of the R01DS0366EJ0150 datasheet and apply to all RA6M5 "B"-feature variants including the R7FA6M5BF3CFP#BA0.

Is the R7FA6M5BF3CFP#BA0 compatible with the Renesas Flexible Software Package (FSP)?

Yes, the R7FA6M5BF3CFP#BA0 is fully supported by Renesas' Flexible Software Package (FSP) v4.x and later, including HAL drivers, middleware (USB Host/Device, Ethernet, CAN FD, TLS), and TrustZone-aware examples. FSP support is validated for all RA6M5 group members, and the R7FA6M5BF3CFP#BA0 is explicitly listed in FSP's device compatibility matrix and configuration tool (e2 studio).
