FAQ

What is the maximum operating frequency of the R7FA6M2AF3CFP#BA5?

The R7FA6M2AF3CFP#BA5 operates at a maximum frequency of 120 MHz using its Arm Cortex-M4 core with FPU. This speed is achievable with the on-chip HOCO or external crystal (8–24 MHz) fed through the PLL. The core maintains zero-wait-state execution from 1-MB flash at 40 MHz, and higher frequencies rely on FCACHE for sustained throughput. System-level timing also depends on peripheral clock dividers and voltage (2.7–3.6 V).

Does the R7FA6M2AF3CFP#BA5 support Ethernet connectivity?

Yes, the R7FA6M2AF3CFP#BA5 integrates a fully compliant IEEE 802.3 Ethernet MAC Controller (ETHERC) with dedicated Ethernet DMA Controller (EDMAC). It supports RMII/MII physical layer interfaces and enables zero-CPU packet handling via DMA. The device requires an external PHY (e.g., LAN8720A) and supports TCP/IP stack acceleration through hardware checksum offload and descriptor-based frame management.

What security features does the R7FA6M2AF3CFP#BA5 include?

The R7FA6M2AF3CFP#BA5 includes the Secure Crypto Engine 7 (SCE7) with hardware-accelerated AES-128/192/256, SHA256, RSA/ECC, TRNG, and GHASH. It also provides 128-bit unique ID, flash area protection, register write protection, and memory protection units (MPU). These features collectively support secure boot, encrypted firmware updates, and cryptographic key management meeting IEC 62443-3-3 SL2 requirements.

How many analog-to-digital converter (ADC) channels does the R7FA6M2AF3CFP#BA5 have?

The R7FA6M2AF3CFP#BA5 integrates two independent 12-bit successive approximation ADC units (ADC12): Unit 0 supports up to 13 input channels, Unit 1 supports up to 9, with two shared analog input pins (AN005/AN105 and AN006/AN106), yielding up to 20 distinct analog input ports. Each unit includes 3 sample-and-hold circuits and supports selectable resolution (8/10/12-bit) and internal reference or temperature sensor inputs.

What is the operating temperature range and package type of the R7FA6M2AF3CFP#BA5?

The R7FA6M2AF3CFP#BA5 is rated for industrial operation from -40°C to +105°C and uses a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch and Sn (Tin) lead finish. This package supports reflow soldering per JEDEC J-STD-020 and provides 75 configurable I/O pins, including 14× 5-V tolerant inputs for legacy interface compatibility.
