The R7F101GGG4CFB#AA1 operates at up to 48 MHz CPU frequency with a single 1.6 V to 5.5 V supply. Its high-speed on-chip oscillator delivers ±1.0% accuracy across the full voltage and −40°C to +125°C temperature range, enabling reliable timing without external crystals in many lighting and power applications.
Does the R7F101GGG4CFB#AA1 support DALI-2 protocol natively?
Yes, the R7F101GGG4CFB#AA1 includes a dedicated DALI-2 physical layer interface on P00 (DALITxD0) and P01 (DALIRxD0), with hardware support for DALI frame timing, collision detection, and noise filtering - meeting EN 62386-102 requirements without external transceivers.
How many analog-to-digital converter (ADC) channels does the R7F101GGG4CFB#AA1 have, and what is their resolution?
The R7F101GGG4CFB#AA1 features a 12-bit successive-approximation ADC with up to 23 input channels, including two dedicated sample-and-hold circuits for simultaneous sampling - critical for accurate current/voltage measurement in digital power supply feedback loops.
