FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FGAFP#X0?
The R5F100FGAFP#X0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction execution times - from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed 32.768 kHz mode - enabling dynamic trade-offs between responsiveness and power savings. This makes the R5F100FGAFP#X0 suitable for both real-time control loops and intermittent sensing tasks.
Does the R5F100FGAFP#X0 support in-system programming and secure firmware updates?
Yes, the R5F100FGAFP#X0 supports full in-system programming via its on-chip debug interface and self-programming flash controller. It includes boot-swap functionality and flash shield window protection to prevent unauthorized access during firmware updates. The 8 KB data flash operates in background mode (BGO), allowing code execution from main memory while rewriting parameters - essential for robust, fail-safe R5F100FGAFP#X0 field deployments.
What are the power supply requirements and low-power capabilities of the R5F100FGAFP#X0?
The R5F100FGAFP#X0 operates from a single 1.6 V to 5.5 V supply, eliminating need for external regulators in many designs. Its ultra-low-power architecture achieves 66 μA/MHz active current and just 0.57 μA in STOP mode with RTC and LVD active - verified across the full -40°C to +85°C industrial temperature range. These specs make the R5F100FGAFP#X0 ideal for energy-harvesting and long-life battery applications.
How many analog input channels and what ADC resolution does the R5F100FGAFP#X0 provide?
The R5F100FGAFP#X0 integrates an 8/10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a factory-calibrated temperature sensor - usable only in HS (high-speed main) mode. This ADC configuration supports simultaneous sampling of multiple sensors (e.g., voltage, current, temperature) in industrial monitoring systems using the R5F100FGAFP#X0 as central acquisition unit.
Is the R5F100FGAFP#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 44-pin LQFP package - including R5F100FGAFP#X0, R5F100FAAFP#X0, and R5F101FGAFP#X0 - share identical pinouts and mechanical footprint (PLQP0044GC-A). Functional differences (e.g., flash size, data flash presence) do not affect signal mapping or PCB layout, enabling hardware reuse across firmware variants and simplifying design migration paths for the R5F100FGAFP#X0.
