FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100FDDFP#V0?
The R5F100FDDFP#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the high-speed on-chip oscillator (±1.0% accuracy over -40°C to +85°C), and the RL78 core's 3-stage pipeline ensures deterministic instruction timing critical for real-time control loops in the R5F100FDDFP#V0.
Does the R5F100FDDFP#V0 include data flash memory, and what is its endurance specification?
Yes, the R5F100FDDFP#V0 integrates 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - a key capability confirmed in the R5F100FDDFP#V0 datasheet for reliable firmware logging and parameter storage.
What package type and pin count does the R5F100FDDFP#V0 use, and is it RoHS compliant?
The R5F100FDDFP#V0 uses a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch), designated by the "FP" suffix and "#V0" tray packaging code. It is RoHS-compliant and qualified for industrial temperature operation (-40°C to +85°C), as specified in Renesas' official ordering information and package drawings for the R5F100FDDFP#V0.
Can the R5F100FDDFP#V0 operate from a single 1.8 V supply, and what is its minimum supply voltage?
Yes, the R5F100FDDFP#V0 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it can run at reduced frequencies (e.g., up to 8 MHz) while maintaining full peripheral functionality, including ADC, RTC, and serial interfaces - a capability explicitly guaranteed in the R5F100FDDFP#V0 electrical characteristics table for low-voltage battery-powered systems.
Which serial communication protocols are supported natively by the R5F100FDDFP#V0 without external components?
The R5F100FDDFP#V0 natively supports CSI (SPI-compatible), UART/LIN (with automatic LIN header detection), and I²C/Simplified I²C - all implemented in hardware with dedicated registers and DMA channels. No external level shifters or transceivers are required for basic operation, as confirmed by the R5F100FDDFP#V0 peripheral summary and register map in the RL78/G13 datasheet.
