FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PLDFA#X0?

The R5F100PLDFA#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling both high-throughput control and extended battery life in the same design.

Does the R5F100PLDFA#X0 include data flash memory, and what are its endurance specifications?

Yes, the R5F100PLDFA#X0 includes 8 KB of on-chip data flash memory. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. The rated endurance is 1,000,000 write/erase cycles at VDD = 1.8–5.5 V, making it suitable for frequent parameter storage in industrial logging and calibration applications.

What package type and pin count does the R5F100PLDFA#X0 use, and what is its temperature rating?

The R5F100PLDFA#X0 uses a 100-pin LFQFP package with 0.5-mm pitch and 14 mm × 14 mm body size. It is rated for industrial operation from –40°C to +85°C (suffix 'D'), confirmed by Renesas' ordering part number structure and datasheet specification tables.

How many analog input channels does the R5F100PLDFA#X0 support, and what ADC resolution is available?

The R5F100PLDFA#X0 supports up to 26 analog input channels with its 10-bit successive-approximation ADC. It includes an internal 1.45 V reference voltage and a factory-calibrated temperature sensor - both accessible via dedicated pins and registers - eliminating the need for external reference components in precision sensing designs.

Can the R5F100PLDFA#X0 operate from a single low-voltage supply, and what is its minimum operating voltage?

Yes, the R5F100PLDFA#X0 operates from a single supply rail ranging from 1.6 V to 5.5 V. Its 1.6 V minimum enables compatibility with primary lithium cells and energy-harvesting sources, while ultra-low-power STOP mode draws just 0.57 μA with RTC and LVD active - critical for maintenance-free remote sensor deployments.
