FAQ

What is the maximum operating frequency and CPU performance of the R5F52306AGFP#30?

The R5F52306AGFP#30 operates at a maximum frequency of 54 MHz using the RXv2 32-bit CPU core, achieving 88.56 DMIPS. Its 5-stage pipeline, on-chip FPU, and zero-wait-state SRAM enable deterministic real-time execution for motor control, sensor processing, and UI rendering tasks within the R5F52306AGFP#30's thermal envelope.

Does the R5F52306AGFP#30 support USB device functionality without external power components?

Yes, the R5F52306AGFP#30 integrates an internal USB regulator that powers the USB transceiver directly from VCC when supplied between 4.0 V and 5.5 V-eliminating the need for an external VCC_USB supply. This simplifies board design for USB-powered peripherals and ensures compliance with USB 2.0 full-speed (12 Mbps) and BC1.2 battery charging specifications in the R5F52306AGFP#30.

What analog peripherals are integrated into the R5F52306AGFP#30?

The R5F52306AGFP#30 integrates a 12-bit 24-channel ADC with 0.83 µs minimum conversion time, two 12-bit DAC channels (0.4–AVCC0−0.5 V output), a temperature sensor, and two dual-channel analog comparators. These peripherals support simultaneous acquisition, calibrated analog output, and hardware-assisted disconnection detection-all accessible without CPU intervention via ELC triggers in the R5F52306AGFP#30.

Is the R5F52306AGFP#30 qualified for extended temperature operation?

Yes, the R5F52306AGFP#30 is rated for −40 to +105°C operation (G version), validated across its full specification range. This makes it suitable for deployment in industrial enclosures near heat-generating equipment, outdoor sensor housings, and automotive under-hood applications where ambient temperatures exceed standard commercial-grade limits for the R5F52306AGFP#30.

How does the capacitive touch sensing unit (CTSU) function in the R5F52306AGFP#30?

The R5F52306AGFP#30's CTSU supports self-capacitance measurement on up to 24 dedicated pins, enabling robust touch key detection with built-in noise cancellation and automatic calibration. It operates independently of the CPU using hardware timers and ELC events, reducing firmware overhead and ensuring consistent response latency-critical for responsive HMI designs built around the R5F52306AGFP#30.
