Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JKDFA#X0 | No data flash memory (0 KB); otherwise identical pinout, peripherals, and code flash (256 KB) | Not suitable where nonvolatile parameter storage or firmware update staging is required | Select R5F101JKDFA#X0 only when data flash functionality is unnecessary and cost reduction is prioritized |
| R5F100JCDFA#X0 | Lower memory configuration: 192 KB flash, 8 KB data flash, 16 KB RAM; same 52-pin LQFP package and D-grade temp range | Appropriate for cost-sensitive applications with reduced firmware footprint and data logging requirements | Choose R5F100JCDFA#X0 when application code size fits within 192 KB and 4 KB RAM headroom is sufficient |
Compared with R5F100JKDFA#X0, R5F101JKDFA#X0 removes data flash but retains full code execution capability, while R5F100JCDFA#X0 trades memory capacity for lower unit cost - both maintain identical industrial temperature rating, packaging, and peripheral compatibility for drop-in layout reuse.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100JKDFA#X0?
The R5F100JKDFA#X0 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency, typical active current is 66 μA per MHz - resulting in ~2.1 mA total at 32 MHz with all peripherals disabled. This value scales linearly with clock speed and active peripheral count, and is confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100JKDFA#X0 support in-system programming and secure firmware updates?
Yes, the R5F100JKDFA#X0 supports full in-system programming via its on-chip debug interface and self-programming flash controller. It includes boot swap functionality for atomic firmware updates and a flash shield window to prevent unauthorized access to critical code sections - all documented in the R01DS0131EJ0380 datasheet Section 1.1 "Code flash memory".
What are the analog capabilities of the R5F100JKDFA#X0, and how many channels can be used simultaneously?
The R5F100JKDFA#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. All channels share a single ADC core, so conversions are sequential - not simultaneous - but scan sequences can be configured in hardware for autonomous multi-channel acquisition. Internal 1.45 V reference and temperature sensor are also accessible, as specified in Section 1.1 "A/D converter" of R01DS0131EJ0380.
Is the R5F100JKDFA#X0 pin-compatible with other RL78/G13 devices in the same package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package (e.g., R5F100JCDFA#X0, R5F100JEDFA#X0, R5F101JKDFA#X0) share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/peripheral configuration group, provided software accounts for differences in flash size, data flash presence, and RAM allocation - verified in Table 1-1 and Figure 1-1 of R01DS0131EJ0380.
What industrial temperature range does the R5F100JKDFA#X0 support, and what does the 'D' suffix indicate?
The R5F100JKDFA#X0 supports an operating ambient temperature range of -40°C to +85°C, denoted by the 'D' in its part number per Figure 1-1 of R01DS0131EJ0380. This qualifies it for industrial applications including factory automation, building controls, and metering equipment where extended thermal stability is required beyond commercial-grade limits.
