Product details
Overview
R5F10NPJDFB#30 from Renesas is a 100-pin LFQFP 256 KB Flash, 16 KB RAM RL78/I1C microcontroller with hardware AES encryption, independent-power-supply RTC, and 24-bit ΔΣ A/D converter - designed for electric AMI power meter applications requiring secure metering, ultra-low-power operation (1.9–5.5 V), and integrated LCD driving capability.
For engineers reviewing the R5F10NPJDFB#30 datasheet, R5F10NPJDFB#30 pinout, R5F10NPJDFB#30 application, or R5F10NPJDFB#30 equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-chain-ready availability details - all grounded in Renesas R01DS0281EJ0231 Rev.2.31 documentation.
Technical Context
The R5F10NPJDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable clock sources including 32 MHz PLL, 24 MHz high-speed on-chip oscillator (±1.0% accuracy), and 32.768 kHz subsystem crystal oscillator. It supports HALT, STOP, and SNOOZE low-power modes with RTC powered independently via VRTC.
It integrates dual A/D systems: a 24-bit ΔΣ ADC (4 channels) for precision metrology and an 8/10-bit SAR ADC (6 channels) for auxiliary sensing, alongside hardware AES-128/192/256 (GCM/ECB/CBC), 32-bit MAC, and event-link controller (ELC) for deterministic peripheral triggering without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NPGDFB#30 | 128 KB Flash, 8 KB RAM, same 100-pin LFQFP package and peripheral set; lacks AES hardware | Targeted at cost-sensitive AMI meters where firmware-level encryption suffices and metrology requirements are less stringent | Select when AES acceleration is unnecessary and 128 KB Flash meets firmware size needs |
| R5F10NMJDFB#30 | 80-pin LFQFP, 128 KB Flash, 8 KB RAM, includes AES; fewer I/O (52 vs. 68), reduced LCD capacity (34 seg vs. 42 seg) | Suitable for compact meters with smaller displays and fewer sensor interfaces, but retains full security and metrology features | Choose for space-constrained designs where 80-pin footprint and 34-segment LCD suffice |
Compared with R5F10NPGDFB#30 and R5F10NMJDFB#30, the R5F10NPJDFB#30 provides maximum on-chip resources (256 KB Flash, 16 KB RAM, 42-segment LCD) and full AES acceleration - making it the highest-capability option in the RL78/I1C family for premium AMI and grid-edge instrumentation.

FAQ
What is the maximum operating frequency of the R5F10NPJDFB#30 CPU core?
The R5F10NPJDFB#30 supports a maximum CPU clock of 32 MHz via its integrated PLL. At this frequency, minimum instruction execution time is 0.03125 µs. The high-speed on-chip oscillator also supports up to 24 MHz (±1.0% accuracy), and the subsystem clock runs at 32.768 kHz for RTC timing. All clocks are software-selectable and configurable via system control registers.
Does the R5F10NPJDFB#30 support hardware AES encryption?
Yes, the R5F10NPJDFB#30 includes a dedicated hardware AES circuit supporting GCM, ECB, and CBC cipher modes with key lengths of 128, 192, and 256 bits. This is confirmed in the datasheet (R01DS0281EJ0231 Rev.2.31, Note 7 and Table 1-1), and distinguishes it from non-"N" variants like R5F11TLEDFB which lack AES.
What are the key differences between R5F10NPJDFB#30 and R5F10NPGDFB#30?
The R5F10NPJDFB#30 has 256 KB Flash and 16 KB RAM, while R5F10NPGDFB#30 has 128 KB Flash and 8 KB RAM. Both are 100-pin LFQFP with AES, but only R5F10NPJDFB#30 supports full 42-segment LCD driving and includes the enhanced 32-bit MAC unit. R5F10NPGDFB#30 is a cost-optimized variant for less demanding AMI implementations.
Can the R5F10NPJDFB#30 operate from a single 3.3 V supply?
Yes, the R5F10NPJDFB#30 operates across 1.9 V to 5.5 V, fully supporting 3.3 V nominal supply. Its high-speed on-chip oscillator maintains ±1.0% accuracy over this range (TA = −20°C to +85°C), and all I/Os are 5 V-tolerant on designated pins. VRTC and VBAT can be supplied separately for RTC retention.
How many channels does the ΔΣ A/D converter have on the R5F10NPJDFB#30?
The R5F10NPJDFB#30 integrates a 24-bit ΔΣ A/D converter with 4 input channels (ANIP0–ANIP3/ANIN0–ANIN3), as specified in the "Outline of Functions" table (Page 13) and "Features" section (Page 1). This is consistent across all 100-pin RL78/I1C devices with AES, including R5F10NPJDFB#30 and R5F10NPGDFB#30.
