Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LDGFA#X0 | Same package and memory (128 KB flash, 8 KB data flash, 12 KB RAM), but rated for −40°C to +105°C (G-grade industrial) | Required for extended-temperature environments such as enclosed motor drives or outdoor enclosures | Select when ambient operating temperature exceeds +85°C; otherwise identical firmware and layout compatibility |
| R5F101LDDFA#X0 | Same pinout and package, but lacks data flash (0 KB); retains full code flash (128 KB) and peripherals | Suitable where firmware-only updates are sufficient and no runtime parameter logging is needed | Choose to reduce BOM cost if data retention during power loss is unnecessary; no PCB change required |
Compared with R5F100LDDFA#X0, R5F100LDGFA#X0 adds extended temperature tolerance without altering power or performance, while R5F101LDDFA#X0 removes data flash to lower unit cost-both retain identical pinout, clocking, and peripheral configuration for drop-in reuse in existing designs.

The R5F100LDDFA#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. The core also supports ultra-low-speed operation down to 32.768 kHz for RTC and low-power monitoring tasks, extending battery life in intermittent-use applications.
Does the R5F100LDDFA#X0 support in-system programming and secure firmware updates?
Yes, the R5F100LDDFA#X0 supports self-programming of both code and data flash memory, including boot swap functionality and flash shield window protection. Block erase prohibition prevents unauthorized rewriting of protected sectors, and the on-chip debug function enables secure firmware updates via standard SWD/JTAG interfaces without exposing sensitive code regions.
How many analog input channels does the R5F100LDDFA#X0 provide, and what is the ADC resolution?
The R5F100LDDFA#X0 features a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25). It includes an internal 1.45 V reference voltage and supports temperature sensor measurement on ANI19. The ADC operates across the full 1.6–5.5 V supply range, enabling direct sensing of sensors with varying output scales.
What serial communication interfaces are integrated into the R5F100LDDFA#X0?
The R5F100LDDFA#X0 integrates three serial interface types: Simplified SPI (CSI) with 2–8 channels, UART/LIN with 2–4 channels (supporting LIN 2.2 protocol), and I²C/Simplified I²C with 3–10 channels. These share multiplexed pins and can operate concurrently, allowing flexible peripheral expansion without external bus controllers.
Is the R5F100LDDFA#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LDDFA#X0 is fully pin-compatible with all other 64-pin LQFP-0.65mm RL78/G13 devices-including R5F100LCDFA#X0, R5F100LEAFA#X0, and R5F101LDDFA#X0-within the same package variant (PLQP0064JA-A). Pin functions, power domains, and reset behavior are consistent across the family, enabling seamless migration based on memory or feature requirements.
