Yes, the R5F100MFDFB#V0 integrates a calendar-mode RTC with year/month/day/hour/minute/second resolution, alarm function, and automatic clock correction. It operates independently in STOP mode with only 0.57 μA current draw when paired with the low-voltage detector (LVD), making it ideal for time-stamped data logging in battery-powered systems.
Can the R5F100MFDFB#V0 perform flash self-programming during runtime?
Yes, the R5F100MFDFB#V0 supports self-programming of both code and data flash memory with boot swap and flash shield window functions. The flash library uses dedicated RAM areas (e.g., start address FAF00H for R5F100xJ variants), enabling secure firmware updates and parameter storage without external programming hardware.
What analog features are available on the R5F100MFDFB#V0?
The R5F100MFDFB#V0 includes an 8/10-bit successive-approximation A/D converter with up to 26 analog input channels, internal 1.45 V reference voltage, and integrated temperature sensor. It supports differential input mode using AVREFP/AVREFM pins and operates across the full 1.6–5.5 V supply range, enabling direct sensor interfacing without external signal conditioning.
Is the R5F100MFDFB#V0 pin-compatible with other RL78/G13 80-pin variants?
Yes, all RL78/G13 80-pin LFQFP variants-including R5F100MFDFB#V0, R5F100MGDFB#V0, and R5F101MFDFB#V0-share identical pinout, package dimensions (12 × 12 mm, 0.50-mm pitch), and electrical characteristics.
