FAQ

What is the maximum operating frequency and associated instruction timing for R5F100EDGNA#U0?

The R5F100EDGNA#U0 operates at up to 32 MHz using its high-accuracy on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 μs. The device also supports ultra-low-speed operation at 32.768 kHz (RTC clock), where instruction timing extends to 30.5 μs - enabling precise real-time scheduling while minimizing power consumption in the R5F100EDGNA#U0.

Does R5F100EDGNA#U0 include integrated data flash memory, and what are its endurance specifications?

Yes, the R5F100EDGNA#U0 includes 4 KB of dedicated data flash memory. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash. The rated endurance is 1,000,000 write/erase cycles (typical), with rewrite voltage compatibility across the full 1.8–5.5 V VDD range - making the R5F100EDGNA#U0 suitable for frequent parameter logging in industrial equipment.

What package type and pin count does R5F100EDGNA#U0 use, and is thermal management supported?

The R5F100EDGNA#U0 uses a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch) with an exposed thermal pad. This package supports efficient heat dissipation in compact, sealed enclosures typical of industrial controllers. The thermal pad must be soldered to a PCB copper pour for optimal thermal performance - a design requirement explicitly defined in the R5F100EDGNA#U0 hardware guidelines.

How does the R5F100EDGNA#U0 support real-time clock functionality, and what calendar features are included?

The R5F100EDGNA#U0 integrates a dedicated real-time clock (RTC) module with calendar support for 99 years, alarm interrupt capability, and clock correction function. It operates independently in STOP mode using the 32.768 kHz subsystem clock (internal or external), maintaining accurate timekeeping at 0.57 μA. This RTC implementation is fully functional in the R5F100EDGNA#U0 without requiring external components.

Is R5F100EDGNA#U0 qualified for industrial temperature operation, and what is its specified range?

Yes, the R5F100EDGNA#U0 is rated for industrial temperature operation with a guaranteed range of −40°C to +105°C (G-grade). This qualification covers full electrical performance including flash read/write, ADC accuracy, oscillator stability, and I/O drive strength - ensuring reliable deployment in demanding environments such as factory floors, outdoor metering, and HVAC systems where the R5F100EDGNA#U0 is commonly applied.
