It integrates UART, I²C, CSI, 16-bit timers, 10-bit ADC (24 channels), RTC, and DMA for embedded control in industrial sensor nodes and power-constrained HMI systems.

For engineers reviewing the R5F100FJDFP#V0 datasheet, R5F100FJDFP#V0 pinout, R5F100FJDFP#V0 application, or R5F100FJDFP#V0 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D), LQFP-44 package with 0.8-mm pitch, integrated data flash rewrite capability (1M cycles), and support for SNOOZE mode wake-up via serial interface events.

Technical Context

The R5F100FJDFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz) and 1 MB address space. Its memory subsystem includes on-chip code flash with block erase security and background data flash programming (BGO) enabling concurrent execution and rewriting.

Power management features include HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and selectable high-accuracy on-chip oscillator (±1.0% from 1–32 MHz). Peripheral integration covers up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 16 16-bit timer channels - all configurable without external components.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100FJDFP#V0?

The R5F100FJDFP#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and -40°C to +85°C ambient conditions. The RL78 core's 3-stage pipeline and efficient instruction set enable this throughput at ultra-low power consumption (66 μA/MHz).

Does the R5F100FJDFP#V0 support background data flash rewriting while executing application code?

Yes, the R5F100FJDFP#V0 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash memory - critical for robust firmware updates and field data logging without halting real-time tasks. Data flash endurance is rated at 1,000,000 write cycles under VDD = 1.8–5.5 V.

What package type and pin count does the R5F100FJDFP#V0 use, and is it RoHS compliant?

The R5F100FJDFP#V0 uses a 44-pin plastic LQFP package (10 × 10 mm, 0.8-mm pitch), identified by Renesas code PLQP0044GC-A. It is lead-free and fully RoHS compliant, meeting JEDEC standard mounting requirements and reflow profiles for automated assembly.

How many analog input channels does the integrated 10-bit ADC support on the R5F100FJDFP#V0?

The R5F100FJDFP#V0 integrates a 10-bit successive-approximation ADC with up to 24 analog input channels. It includes an internal 1.45 V reference voltage and on-die temperature sensor, both selectable in high-speed main mode. Input voltage range is tied to VDD (1.6–5.5 V), enabling direct sensor interfacing without external references.

What debug interface is supported by the R5F100FJDFP#V0, and which pins are used?

The R5F100FJDFP#V0 supports single-wire debug (SWD) via dedicated TOOLRxD (P11) and TOOLTxD (P12) pins - eliminating need for external debug headers. These pins double as UART I/O, allowing shared use for bootloader communication and development debugging without additional PCB footprint.
