FAQ
What is the maximum operating frequency of the R7FA6M1AD3CFM#BA0?
The R7FA6M1AD3CFM#BA0 operates at a maximum frequency of 120 MHz using its Arm Cortex-M4 core with FPU. This frequency is achievable with the main clock oscillator (8–24 MHz) and PLL configuration, and is validated across the full -40°C to +105°C temperature range. The R7FA6M1AD3CFM#BA0 maintains zero wait-state execution from its 512 KB code flash memory at 40 MHz, ensuring deterministic real-time response.
Does the R7FA6M1AD3CFM#BA0 support USB device and host modes?
Yes, the R7FA6M1AD3CFM#BA0 USB 2.0 Full-Speed (USBFS) module supports both device and host modes as defined in the USB Specification 2.0. It includes an on-chip transceiver, eliminating the need for external PHY components. In host mode, it supports low-speed devices; in device mode, it handles all four transfer types (control, interrupt, bulk, isochronous). The R7FA6M1AD3CFM#BA0 allocates up to 10 pipes for endpoint management, with flexible assignment per application requirements.
How many analog input channels does the R7FA6M1AD3CFM#BA0 support?
The R7FA6M1AD3CFM#BA0 integrates two independent 12-bit ADC12 units: ADC12 unit 0 supports up to 11 analog input channels, and unit 1 supports up to 8 channels. Due to shared port pins (AN005/AN105, AN006/AN106), the total number of unique analog input pins is 17. Both units include sample-and-hold circuits, selectable resolution (8/10/12-bit), and support for internal references including the on-die temperature sensor (TSN) and DAC12 outputs - all confirmed in the R7FA6M1AD3CFM#BA0 datasheet Section 42.
What security features are implemented in the R7FA6M1AD3CFM#BA0?
The R7FA6M1AD3CFM#BA0 incorporates the Secure Crypto Engine 7 (SCE7), providing hardware-accelerated symmetric (AES-128/192/256, 3DES, ARC4), asymmetric (RSA, DSA, ECC), and hash (SHA-1/224/256, MD5, GHASH) operations. It also includes a True Random Number Generator (TRNG), 128-bit unique ID, flash area protection, SRAM ECC/parity, and register write protection. These features enable secure boot, encrypted firmware updates, and TLS offload - all verified in the R7FA6M1AD3CFM#BA0 User's Manual Section 1.12.
Is the R7FA6M1AD3CFM#BA0 pin-compatible with other RA6M1 group members?
No, the R7FA6M1AD3CFM#BA0 is not pin-compatible with 100-pin RA6M1 variants (e.g., R7FA6M1AD3CFP or R7FA6M1AD3CLJ) due to its 64-pin LQFP package (PLQP0064KB-C). However, it shares identical peripheral sets, memory map, and software API with the full RA6M1 family, enabling scalable design reuse through Renesas' Flexible Software Package (FSP). Pin assignments for the R7FA6M1AD3CFM#BA0 are documented in Table 1.16 of the R7FA6M1AD3CFM#BA0 datasheet.
