FAQ

What is the maximum operating frequency of the R7FA6M5BF3CFP#AA0?

The R7FA6M5BF3CFP#AA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved with the on-chip PLL driven by the main clock oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core maintains full performance across its -40°C to +105°C industrial temperature range, with voltage regulation supported between 2.7 V and 3.6 V.

Does the R7FA6M5BF3CFP#AA0 support CAN FD, and how many channels are available?

Yes, the R7FA6M5BF3CFP#AA0 supports CAN with Flexible Data-rate (CAN FD) on two independent channels, compliant with ISO 11898-1. Each channel provides 16 transmit and 16 receive buffers, supporting data rates up to 5 Mbps and payloads up to 64 bytes. This capability is confirmed in the RA6M5 datasheet (R01DS0366EJ0150) and applies specifically to the "B" variant in the part numbering scheme, which R7FA6M5BF3CFP#AA0 belongs to.

What security features does the R7FA6M5BF3CFP#AA0 include beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5BF3CFP#AA0 integrates the Secure Crypto Engine 9 (SCE9) with hardware accelerators for AES-128/256, RSA-2048/4096, ECC, SHA224/256, and GHASH. It also includes tamper detection pins, power analysis resistance, a 128-bit unique ID, and device lifecycle management. These features are documented in the RA6M5 datasheet Section 1.1 and apply directly to the R7FA6M5BF3CFP#AA0 as a member of the "B" feature-set group.

Which package and pin count does the R7FA6M5BF3CFP#AA0 use?

The R7FA6M5BF3CFP#AA0 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 pins for RMII Ethernet, dual CAN FD, USBHS/USBFS, QSPI, and RTC battery backup (VBATT). This package is explicitly listed in Table 1.13 of the RA6M5 datasheet for the R7FA6M5BF3CFP variant.

Does the R7FA6M5BF3CFP#AA0 include Ethernet MAC, and what interface does it support?

Yes, the R7FA6M5BF3CFP#AA0 includes an Ethernet MAC controller compliant with IEEE 802.3, supporting 10/100 Mbps operation. It implements the Reduced Media Independent Interface (RMII) only-requiring six dedicated pins (TXD0/TXD1, TX_EN, RXD0/RXD1, CRS_DV, REF_CLK) and an external PHY. The RMII interface is confirmed in Table 1.14 of the RA6M5 datasheet and applies to all R7FA6M5 variants including R7FA6M5BF3CFP#AA0.
