FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BFAFP#10?
The R5F104BFAFP#10 operates at a maximum frequency of 32 MHz, delivering 44 DMIPS performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across -20°C to +85°C ambient conditions. The RL78 CPU core's 3-stage pipeline ensures deterministic timing for real-time control loops in the R5F104BFAFP#10.
Does the R5F104BFAFP#10 support background data flash rewriting while executing application code?
Yes, the R5F104BFAFP#10 supports background operation (BGO) for data flash rewriting. Instructions can be executed from program memory during data flash write/erase operations, enabling seamless firmware updates and parameter storage without halting real-time tasks. The R5F104BFAFP#10 guarantees 1,000,000 rewrite cycles at VDD = 1.8–5.5 V.
What analog features are integrated into the R5F104BFAFP#10 for sensor interfacing?
The R5F104BFAFP#10 integrates a 10-bit resolution ADC with 16 analog input channels, internal 1.45 V reference voltage, on-chip temperature sensor, and two analog comparators with window mode. These features allow direct connection of thermistors, potentiometers, and current-sense amplifiers without external components - critical for compact sensor node designs using the R5F104BFAFP#10.
How does the Event Link Controller (ELC) improve system responsiveness in the R5F104BFAFP#10?
The ELC in the R5F104BFAFP#10 enables hardware-level linking of 19–26 peripheral events (e.g., ADC conversion complete → DMA transfer → timer trigger), eliminating CPU intervention and interrupt latency. This reduces response time for time-critical sequences - such as motor phase switching - by up to 90% compared to software-driven ISR chains in the R5F104BFAFP#10.
What is the industrial temperature range supported by the R5F104BFAFP#10, and how is it indicated in the part number?
The R5F104BFAFP#10 is qualified for -40°C to +85°C operation (D-grade industrial specification), denoted by the "D" in the ordering code suffix position. This grade ensures reliable operation in factory automation, building controls, and outdoor equipment where ambient extremes demand robust silicon characterization - a key requirement met by the R5F104BFAFP#10.
