FAQ
What is the maximum operating frequency and core architecture of the R5F104FDAFP#10?
The R5F104FDAFP#10 features a 16-bit RL78 CPU core with 3-stage pipeline, achieving 44 DMIPS at its maximum 32 MHz operating frequency. Instruction execution time ranges from 0.03125 µs (high-speed mode) to 30.5 µs (ultra-low-speed 32.768 kHz mode), supporting both performance-critical and ultra-low-power use cases within the same device.
Does the R5F104FDAFP#10 support in-system programming and secure flash protection?
Yes, the R5F104FDAFP#10 supports self-programming of code flash and data flash with boot swapping and flash shield window functionality. It also includes security features such as prohibition of block erase and rewriting, preventing unauthorized firmware modification while enabling safe field updates via the on-chip debug interface.
What analog peripherals are integrated into the R5F104FDAFP#10?
The R5F104FDAFP#10 integrates a 16-channel 10-bit ADC with internal 1.45 V reference voltage and temperature sensor, two 8-bit DACs with 0–VDD output range and real-time update capability, and an analog comparator with selectable internal/external reference - all usable simultaneously without external support components.
How does the Event Link Controller (ELC) enhance system responsiveness in the R5F104FDAFP#10?
The ELC in the R5F104FDAFP#10 enables hardware-level linking of up to 26 peripheral events (e.g., ADC end-of-conversion → DTC transfer → UART transmission) without CPU involvement. This reduces interrupt latency to sub-microsecond levels and frees the CPU for higher-layer tasks, critical in deterministic motor control and real-time data aggregation.
Is the R5F104FDAFP#10 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 44-pin LQFP (PLQP0044GC-A) package - including R5F104FAAFP#10, R5F104FEAFP#10, and R5F104FGAFP#10 - share identical pinouts and electrical characteristics. This allows memory-size-based scalability without PCB layout changes, simplifying design reuse across product tiers.
