Technical Context
The R5F104GAGFB#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), and integrates Event Link Controller (ELC) for deterministic peripheral triggering without CPU intervention. It features Data Transfer Controller (DTC) with chain transfer and background operation during data flash rewriting.

Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 µs at this frequency, enabling deterministic real-time control loops with sub-25 µs latency. Performance scales linearly with clock speed, and the high-accuracy on-chip oscillator maintains ±1.0% stability across voltage and temperature ranges - eliminating need for external crystal in many applications.
Does the R5F104GAGFB#10 support hardware RTC with calendar functionality?
Yes, the R5F104GAGFB#10 integrates a full-featured real-time clock (RTC) with calendar support for years, months, days, hours, minutes, and seconds; alarm interrupt capability; and automatic clock correction. It operates independently in STOP mode with only 0.60 μA consumption, powered by VDD or optional backup supply - making it suitable for time-stamped data logging and scheduled wake-up in battery-powered systems.
How many analog input channels and what resolution does the ADC in R5F104GAGFB#10 provide?
The R5F104GAGFB#10 features a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI15, plus ANI16–ANI19 on select pins). It supports internal 1.45 V reference voltage and on-die temperature sensor, and operates across the full 1.6–5.5 V supply range - enabling direct battery voltage monitoring and precision sensor interfacing without external references.
