FAQ

What is the maximum operating frequency and performance of the R5F100PGAFA#X0?

The R5F100PGAFA#X0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core supports configurable instruction timing, enabling minimum execution times of 0.03125 μs at full speed or 30.5 μs in ultra-low-speed mode using the 32.768 kHz subsystem clock - making R5F100PGAFA#X0 suitable for both high-throughput control and ultra-low-power wake-on-event tasks.

Does the R5F100PGAFA#X0 include integrated data flash memory, and what is its endurance?

Yes, the R5F100PGAFA#X0 includes 8 KB of on-chip data flash memory with guaranteed endurance of 1,000,000 write/erase cycles (typical) across the full 1.8–5.5 V supply range. It supports background operation (BGO), allowing CPU code execution from program memory during data flash rewrites - a critical capability for reliable firmware parameter updates in R5F100PGAFA#X0-based systems.

What low-power modes does the R5F100PGAFA#X0 support, and what is its lowest current draw?

The R5F100PGAFA#X0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified at VDD = 1.8 V and TA = 25°C. This ultra-low quiescent current enables multi-year battery operation in R5F100PGAFA#X0-based portable and remote sensing applications.

Can the R5F100PGAFA#X0 perform analog-to-digital conversion, and how many channels are available?

Yes, the R5F100PGAFA#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated pins (P20/AVREFP, P21/AVREFM, and ANI21). These features allow R5F100PGAFA#X0 to replace external ADCs and references in compact sensor interface designs.

Is the R5F100PGAFA#X0 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100PGAFA#X0 is fully pin-compatible with all other RL78/G13 devices in the 100-pin LQFP-0.65mm package (e.g., R5F100PFAFA#X0, R5F100PHAFA#X0, R5F100PLAFA#X0), sharing identical pin configuration, electrical characteristics, and peripheral mapping. This allows seamless migration between memory/configurations without PCB redesign - a key advantage when scaling R5F100PGAFA#X0 into higher-flash or alternate-feature variants.
