Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101FCDFP#X0 | No data flash memory (0 KB); identical core, peripherals, and package | Not suitable where field-upgradable configuration storage is required | Select when firmware-only operation suffices and cost reduction is prioritized over nonvolatile parameter retention |
| R5F100FCAFP#V0 | Same flash/RAM/data flash specs but in tray packaging (not embossed tape); identical electrical behavior | Preferred for low-volume prototyping or manual assembly; same functional use case | Choose for evaluation or small-batch builds where tape-and-reel automation is unnecessary |
Compared with R5F100FCDFP#X0, R5F101FCDFP#X0 removes data flash to lower cost and die size while retaining full code flash and peripheral compatibility, whereas R5F100FCAFP#V0 offers identical functionality in alternate packaging for flexibility in production flow.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100FCDFP#X0?
The R5F100FCDFP#X0 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance at 66 μA/MHz active current. At 32 MHz, typical active current is ~2.1 mA. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA-verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F100FCDFP#X0 support LIN bus communication, and how is it implemented?
Yes, the R5F100FCDFP#X0 supports LIN bus communication through its UART peripherals, which include LIN-mode functionality (break detection, sync field handling, and checksum calculation). UART0 and UART1 can be configured for LIN 2.2 compliance, enabling direct connection to LIN transceivers without external protocol assist hardware.
What are the data flash endurance and voltage requirements for rewriting the R5F100FCDFP#X0?
The R5F100FCDFP#X0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with rewrite voltage range of 1.8 V to 5.5 V. Background operation allows program execution from code flash during data flash rewriting-critical for runtime parameter updates in industrial firmware.
How many analog input channels does the R5F100FCDFP#X0 support, and what ADC resolution is available?
The R5F100FCDFP#X0 integrates a 10-bit successive-approximation ADC with up to 24 analog input channels (ANI0–ANI23), selectable via software. It supports internal 1.45 V reference voltage and on-chip temperature sensor readout-both accessible through dedicated ANI pins as defined in the RL78/G13 pin configuration tables.
Is the R5F100FCDFP#X0 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?
Yes, all RL78/G13 devices in the 44-pin LQFP package-including R5F100FCDFP#X0, R5F101FCDFP#X0, and R5F100FCAFP#V0-share identical pinouts and mechanical footprint. Functional differences (e.g., data flash presence) do not affect PCB layout, enabling drop-in replacement where firmware and feature requirements align.
