FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100MFAFB#10?
The R5F100MFAFB#10 operates up to 32 MHz with a typical active current of 66 μA per MHz. At full speed, total active current is approximately 2.1 mA (VDD = 3.3 V, TA = 25°C). Its ultra-low-power STOP mode draws just 0.57 μA while maintaining RTC and LVD functionality - critical for battery-backed applications.
Does the R5F100MFAFB#10 include on-chip debug capability, and what interface does it use?
Yes, the R5F100MFAFB#10 includes full on-chip debug support compatible with Renesas E1/E2 emulators via SWD (Serial Wire Debug). No external debug header is needed - debug signals share pins with standard GPIO, enabling in-system programming and real-time trace without footprint overhead.
What are the key differences between R5F100MFAFB#10 and R5F101MFAFB#10?
The R5F100MFAFB#10 includes 8 KB of data flash memory with background rewrite (BGO) and flash shield security, while R5F101MFAFB#10 omits data flash entirely. All other specifications - core, RAM, peripherals, pinout, and package - are identical. Use R5F100MFAFB#10 when non-volatile parameter storage is required onboard.
Can the R5F100MFAFB#10 drive 5 V logic directly, and which I/O pins support higher voltage tolerance?
The R5F100MFAFB#10 I/O ports support different voltage tolerances: up to 4 pins are rated for 6 V N-ch open-drain operation (e.g., P00–P03), while others tolerate VDD or EVDD (up to 5.5 V). It does not drive 5 V logic levels directly from CMOS outputs, but its 6 V-tolerant pins safely interface with 5 V peripherals in sink-mode configurations.
Is the R5F100MFAFB#10 qualified for industrial temperature range, and what is its specified operating ambient temperature?
Yes, the R5F100MFAFB#10 carries the 'G' suffix indicating industrial qualification with guaranteed operation from -40°C to +105°C. This rating applies across all electrical specifications in the datasheet, including flash endurance, ADC accuracy, and oscillator stability - making it suitable for harsh environments like factory floors and outdoor metering enclosures.
