FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100JGAFA#X0?
The R5F100JGAFA#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This metric is measured under standard conditions (VDD = 2.7–5.5 V, TA = –40°C to +105°C) and reflects the RL78 CPU core's efficiency in executing typical embedded workloads - including ISR handling, peripheral control, and arithmetic operations required by the R5F100JGAFA#X0's target applications.
Does the R5F100JGAFA#X0 support background data flash rewriting while executing code from main flash?
Yes, the R5F100JGAFA#X0 supports Background Operation (BGO) for data flash rewriting. During BGO, the CPU can execute instructions from program memory while the data flash (8 KB) is being rewritten - enabling uninterrupted real-time tasks such as sensor acquisition or communication. This capability is confirmed in the R01DS0131EJ0380 datasheet and applies directly to the R5F100JGAFA#X0 as a member of the RL78/G13 G-grade family with data flash enabled.
What is the ADC resolution, channel count, and reference voltage option for the R5F100JGAFA#X0?
The R5F100JGAFA#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports both external reference voltages and an internal 1.45 V reference (selectable only in HS mode). The ADC operates across the full supply range (VDD = 1.6–5.5 V), making it suitable for direct battery voltage monitoring, thermistor reading, and industrial sensor interfacing without external reference components - a confirmed specification for the R5F100JGAFA#X0 per RL78/G13 family documentation.
Is the R5F100JGAFA#X0 qualified for industrial temperature operation, and what is its rated range?
Yes, the R5F100JGAFA#X0 is qualified for industrial temperature operation with a rated ambient range of –40°C to +105°C. This G-grade qualification is explicitly assigned in the part number decoding ('G' = Industrial, +105°C) and verified in Table 1-1 of the R01DS0131EJ0380 datasheet. The device undergoes extended thermal stress testing to ensure reliable operation in demanding environments such as motor drives, factory automation controllers, and outdoor utility equipment where the R5F100JGAFA#X0 is deployed.
How many UART/LIN channels does the R5F100JGAFA#X0 support, and are they hardware-accelerated?
The R5F100JGAFA#X0 supports up to four UART channels, each with LIN-bus protocol support - implemented in hardware with dedicated baud rate generators, break detection, and sync byte handling. These UART peripherals are fully autonomous and do not require bit-banging; they are confirmed functional across all RL78/G13 variants with UART capability, including the R5F100JGAFA#X0 as a 52-pin G-grade device with full peripheral enablement per the family datasheet.
