FAQ

What is the maximum operating frequency of the R7FA6M1AD2CLJ#AC5?

The R7FA6M1AD2CLJ#AC5 operates at a maximum frequency of 120 MHz using its Arm Cortex-M4 core with FPU. This clock speed is achieved via the on-chip PLL driven by the main oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core sustains this frequency across its full -40°C to +85°C operating range with 2.7–3.6 V supply, enabling deterministic real-time execution for motor control and protocol stacks.

Does the R7FA6M1AD2CLJ#AC5 support USB device and host modes?

Yes, the R7FA6M1AD2CLJ#AC5 USB 2.0 Full-Speed (USBFS) module supports both device and host modes per the Universal Serial Bus Specification 2.0. It includes an on-chip transceiver, 10 configurable pipes, and buffer memory - allowing the R7FA6M1AD2CLJ#AC5 to function as a USB CDC device (e.g., virtual COM port) or enumerate as a host for HID peripherals like keyboards or BLE dongles without external PHY components.

How many analog input channels does the R7FA6M1AD2CLJ#AC5 support?

The R7FA6M1AD2CLJ#AC5 integrates two independent 12-bit ADC12 units: ADC0 supports up to 11 analog input channels, and ADC1 supports up to 8 channels. Two channels are shared between units (AN005/AN105, AN006/AN106), yielding 17 distinct analog input pins. Each unit includes 3 sample-and-hold circuits and supports selectable resolution (12/10/8-bit) and internal references including the on-die temperature sensor.

What security features are implemented in the R7FA6M1AD2CLJ#AC5?

The R7FA6M1AD2CLJ#AC5 incorporates the Secure Crypto Engine 7 (SCE7), providing hardware-accelerated AES-128/192/256, SHA256, RSA/ECC, TRNG, and GHASH. Additional protections include SRAM ECC (32 KB), parity (224 KB), register write protection, illegal memory access detection, Clock Frequency Accuracy Measurement Circuit (CAC), and Independent Watchdog Timer (IWDT) with dedicated oscillator - collectively supporting IEC 61508 SIL2 and ISO 26262 ASIL-B development.

What package type and pin count does the R7FA6M1AD2CLJ#AC5 use?

The R7FA6M1AD2CLJ#AC5 uses a 100-pin Land Grid Array (LGA) package designated PTLG0100JA-A, measuring 7 mm × 7 mm with 0.65 mm pitch and Sn (tin) terminal finish. This compact, thermally efficient package provides 67 GPIOs (including 14 5-V tolerant), 9 dedicated inputs, and full access to all peripherals - making it ideal for space-constrained industrial control modules where thermal dissipation and EMI resilience are critical.
