FAQ
What is the maximum operating frequency and corresponding performance of the R5F100JHAFA#V0?
The R5F100JHAFA#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. This flexibility allows the R5F100JHAFA#V0 to balance performance and power across diverse operational phases.
Does the R5F100JHAFA#V0 support in-circuit debugging and programming?
Yes, the R5F100JHAFA#V0 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. It supports full-speed debugging, flash programming via SWD interface, and real-time trace capabilities. The R5F100JHAFA#V0 also enables self-programming of both code and data flash memory with boot swap and flash shield window features for secure firmware updates in the field.
How many analog input channels does the R5F100JHAFA#V0 ADC support, and what reference options are available?
The R5F100JHAFA#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports multiple reference configurations: external VDD, internal 1.45 V reference (available only in HS mode), and differential AVREFP/AVREFM inputs. This enables precise ratiometric measurements, temperature sensing via the on-chip sensor, and flexible signal conditioning for industrial analog front-ends.
What low-power modes are available on the R5F100JHAFA#V0, and what is the lowest achievable current draw?
The R5F100JHAFA#V0 offers HALT, STOP, and SNOOZE low-power modes. In HALT mode with only RTC and LVD active, it draws just 0.57 μA - verified at VDD = 1.8–5.5 V and TA = –40°C to +85°C. STOP mode achieves sub-μA retention with RAM and RTC preserved, while SNOOZE enables peripheral-triggered wake-up without full CPU restart, making the R5F100JHAFA#V0 ideal for energy harvesting and battery-constrained deployments.
Is the R5F100JHAFA#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100JHAFA#V0 is fully pin-compatible with all other RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCAFA#V0, R5F100JGAFA#V0), sharing identical pin configuration, electrical characteristics, and peripheral mapping. This allows direct substitution within the same footprint for memory or feature scaling - provided software accounts for differences in flash/RAM size and enabled peripherals per variant.
