What is the A/D converter specification for the R5F10269DSP#55?
The R5F10269DSP#55 integrates a 10-bit successive-approximation A/D converter with 11 input channels (ANI0–ANI3, ANI16–ANI22), internal 1.45 V reference voltage, and an integrated temperature sensor. Conversion time is 14–20 μs depending on clock configuration, and it operates across the full 1.8–5.5 V supply range.
Is the R5F10269DSP#55 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10269DSP#55 shares identical pinout and package (LSSOP-20) with all R5F102xxDSP#55 and R5F103xxDSP#55 variants, including R5F10268DSP#55 and R5F10267DSP#55. Pin functions are consistent across the 20-pin RL78/G12 family, enabling drop-in replacement for memory or feature upgrades.
