FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100JFAFA#V0?
The R5F100JFAFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy (VDD = 1.8–5.5 V, TA = –20 to +85°C). At this frequency, active current consumption is 66 μA/MHz - resulting in approximately 2.1 mA typical at 32 MHz with all peripherals disabled. The device also achieves 0.57 μA in STOP mode with RTC and LVD active.
Does the R5F100JFAFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F100JFAFA#V0 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to protect designated code regions from read/write access. It also implements boot swap capability for safe firmware updates - allowing validation of new firmware in a secondary bank before atomic activation.
How many analog input channels does the R5F100JFAFA#V0 provide, and what ADC resolution and reference options are available?
The R5F100JFAFA#V0 provides 24 analog input channels with a 10-bit successive approximation ADC. It supports internal 1.45 V reference (VREF+) and AVREFM (VREF–) pins for differential measurement, and operates across the full 1.6–5.5 V supply range. The internal temperature sensor is accessible via ANI19 and calibrated for ±2.5°C accuracy.
What low-power modes are available on the R5F100JFAFA#V0, and how quickly can it wake from STOP mode?
The R5F100JFAFA#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), it retains RTC and LVD operation while disabling CPU and most peripherals. Wake-up from STOP is achieved in ≤10 μs via external interrupt, RTC alarm, or LVD event - enabling rapid response in duty-cycled sensor applications.
Is the R5F100JFAFA#V0 pin-compatible with other RL78/G13 variants in the 52-pin LQFP package?
Yes, all RL78/G13 52-pin LQFP variants - including R5F100JCAFA#V0 through R5F100JLAFA#V0 and R5F101Jx series - share identical pinouts and mechanical footprint (PLQP0052JA-A). This allows hardware reuse across memory/configurations, provided firmware accounts for differences in flash size, data flash presence, and RAM allocation.
