FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PFDFA#V0?

The R5F100PFDFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time.

Does the R5F100PFDFA#V0 support in-system programming and secure firmware updates?

Yes, the R5F100PFDFA#V0 supports full in-system programming via on-chip debug interface and includes boot swap functionality for safe firmware updates. It also features flash shield window and block erase prohibition to prevent unauthorized access or accidental overwrite of protected code regions.

How many analog input channels does the R5F100PFDFA#V0 ADC support, and what reference options are available?

The R5F100PFDFA#V0 integrates a 10-bit A/D converter with up to 26 analog input channels. It supports external VDD as reference or internal 1.45 V reference voltage, enabling accurate measurements across 1.6–5.5 V supply range without external reference components.

What low-power modes are available on the R5F100PFDFA#V0, and what is the lowest achievable current draw?

The R5F100PFDFA#V0 provides HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C - ideal for battery-backed real-time clock and wake-up event detection.

Is the R5F100PFDFA#V0 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 100-pin LQFP-0.65mm package (e.g., R5F100PLDFA#V0, R5F101PFAFA#V0) share identical pinouts and electrical characteristics. This enables direct substitution within the same footprint for memory or feature scaling without PCB redesign.
