Product details
Overview
R5F10NPJDFB#15 from Renesas is an RL78/I1C 16-bit microcontroller with 512 KB code flash (256 KB × 2 banks), 32 KB RAM, and 2 KB data flash, featuring a 24-bit ΔΣ A/D converter (3 channels), independent-power-supply RTC, hardware AES engine (128/192/256-bit), and 32-bit multiply-accumulator - designed for ultra-low-power utility metering applications including electric, gas, and water meters operating across 1.6–5.5 V.
For engineers reviewing the R5F10NPJDFB#15 datasheet, R5F10NPJDFB#15 pinout, R5F10NPJDFB#15 application, or R5F10NPJDFB#15 equivalent, key selection considerations include its 80-pin LFQFP package, industrial temperature range (−40°C to +85°C), dual-bank flash for live firmware updates, ΔΣ ADC SNDR ≥69 dB at ×16 gain, and AES-GCM/ECB/CBC support for secure metrology data handling.
Technical Context
The R5F10NPJDFB#15 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz PLL clock). It integrates a dedicated 24-bit ΔΣ A/D converter with PGA (×1–×32), simultaneous sample-and-hold for three channels, and internal reference voltage outputs (1.5/2.0/2.5 V) usable by its 12-bit SAR ADC.
Its power management includes HALT, STOP, and SNOOZE modes; on-chip POR/LVD circuits with 14-level detection on VDD; independent RTC power domain (VRTC); and hardware-based bank programming enabling safe in-field firmware updates without halting execution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NMLDFB#30 | Same RL78/I1C family, identical 512 KB flash, 32 KB RAM, 80-pin LFQFP, and feature set; differs only in packaging specification (#30 = tray vs #15 = unspecified but compatible tray format) | No functional difference; both rated for industrial −40°C to +85°C operation and utility metering | Select R5F10NMLDFB#30 if tray packaging consistency with existing procurement is required |
| R5F10NPLDFB#30 | 100-pin LFQFP variant with +16 I/O pins, +2 ΔΣ ADC channels (4 total), +2 UARTMG channels, and +8 segment outputs for larger LCDs | Suitable for advanced meters requiring more sensor inputs, larger display, or additional serial interfaces (e.g., dual RF + PLC) | Choose R5F10NPLDFB#30 only when extra I/O, ADC channels, or LCD drive capability is needed - not pin-compatible |
Compared with R5F10NMLDFB#30, R5F10NPJDFB#15 offers identical metrology-grade peripherals and security features in the same 80-pin footprint; versus R5F10NPLDFB#30, it trades I/O scalability for compactness and lower BOM cost where full 100-pin resources are unnecessary.

FAQ
What is the maximum sampling rate of the 24-bit ΔΣ A/D converter in R5F10NPJDFB#15?
The R5F10NPJDFB#15 supports a maximum ΔΣ A/D converter sampling rate of 3.906 kHz at gain ×1, with programmable decimation filtering. At higher PGA gains (e.g., ×16), the effective sampling rate reduces to maintain SNDR ≥69 dB - verified in the R01DS0382EJ0112 datasheet Section 1.6.
Does R5F10NPJDFB#15 support in-application programming (IAP) of its code flash memory?
Yes, R5F10NPJDFB#15 supports self-programming with flash shield window protection and dual-bank architecture. This allows one bank to execute code while the other is rewritten - enabling secure, uninterrupted firmware updates in deployed utility meters without external programmers.
What are the supported AES cipher modes and key lengths for R5F10NPJDFB#15?
R5F10NPJDFB#15 integrates a hardware AES engine supporting GCM, ECB, and CBC modes with key lengths of 128, 192, and 256 bits. These are confirmed in the "AES circuit" section of the R01DS0382EJ0112 datasheet and enable FIPS-compliant data encryption for DLMS/COSEM and firmware signing.
How many independent power domains does R5F10NPJDFB#15 have, and why does it matter?
R5F10NPJDFB#15 has two independent power domains: VDD/EVDD0 for digital logic and VRTC for the real-time clock. This separation ensures RTC continues accurate timekeeping during main power failure - a mandatory requirement for revenue-grade metering and tamper-evident logging per IEC 62053-21.
Can R5F10NPJDFB#15 drive a segment LCD directly, and what is its maximum segment count?
Yes, R5F10NPJDFB#15 includes an integrated LCD controller/driver supporting up to 34 segment signals and 4 common outputs (or 30 segments / 8 commons) in its 80-pin configuration. This eliminates external LCD drivers in basic utility displays, reducing BOM cost and PCB area for compact meter designs.
