FAQ

What is the maximum operating frequency and associated power consumption of the R5F100JGAFA#30?

The R5F100JGAFA#30 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-mode current is 66 μA/MHz - resulting in approximately 2.1 mA typical at 32 MHz with all peripherals disabled. The device maintains 0.57 μA in STOP mode with RTC and LVD active, enabling multi-year battery operation in sensor applications.

Does the R5F100JGAFA#30 support in-system programming and secure firmware updates?

Yes, the R5F100JGAFA#30 supports full in-system programming via its on-chip debug interface. It includes flash shield window protection, block erase prohibition, and boot swap functionality - enabling secure dual-bank firmware updates without external programmers. The flash self-programming library reserves RAM starting at address FAF00H, and data flash rewrites tolerate VDD = 1.8–5.5 V with 1 million cycle endurance.

How many analog input channels does the R5F100JGAFA#30 support, and what reference options are available?

The R5F100JGAFA#30 supports up to 26 analog input channels across multiple ports (P20–P27, P30–P37, etc.). It features a selectable internal 1.45 V reference voltage for the 10-bit ADC, usable only in HS (high-speed main) mode. External references may be applied via AVREFP/AVREFM pins. The integrated temperature sensor is calibrated and accessible through dedicated ADC channel ANI25.

Is the R5F100JGAFA#30 pin-compatible with other RL78/G13 variants in the 52-pin LQFP package?

Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCAFA#30, R5F100JDAFA#30, R5F101JGAFA#30) share identical pinouts and mechanical footprint. Functional differences (e.g., flash size, data flash presence, RAM capacity) do not affect physical layout - enabling drop-in replacement during design iteration or cost optimization, provided firmware and configuration match the variant's resources.

What industrial certifications and operating conditions apply to the R5F100JGAFA#30?

The R5F100JGAFA#30 carries G-grade qualification, specifying guaranteed operation from –40°C to +105°C ambient temperature - meeting industrial requirements for extended thermal reliability. It complies with AEC-Q100 stress test qualifications for integrated circuits and supports functional safety development per IEC 61508 SIL2 guidelines, with built-in LVD, WDT, and clock failure detection mechanisms documented in the RL78/G13 Hardware Manual.
