Product details
Overview
R5F10NPJDFB#50 from Renesas is a 100-pin, 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 ultra-low power operation (1.9–5.5 V), secure firmware updates, and high-precision metrology.
For engineers reviewing the R5F10NPJDFB#50 datasheet, R5F10NPJDFB#50 pinout, R5F10NPJDFB#50 application, or R5F10NPJDFB#50 equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-chain-ready availability details - all grounded in Renesas' official R01DS0281EJ0231 Rev.2.31 specification.
Technical Context
The R5F10NPJDFB#50 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 15 kHz low-speed oscillator. It supports HALT, STOP, and SNOOZE low-power modes with VDD = 1.9–5.5 V operation and TA = –40 to +85°C ambient range.
It integrates dual A/D subsystems: a 24-bit ΔΣ ADC (4 channels) for precision energy measurement and an 8/10-bit SAR ADC (6 channels) for auxiliary sensing. The independent-power-supply RTC uses VRTC and supports calendar, alarm, and correction functions - critical for time-of-use billing in smart meters.

Both operate across the full 1.9–5.5 V supply range, supporting simultaneous high-precision metrology and auxiliary sensing in AMI applications.
What package type and pin count does the R5F10NPJDFB#50 use?
The R5F10NPJDFB#50 uses a 100-pin plastic LFQFP package (14 × 14 mm, 0.5 mm pitch) with embossed tape packaging (#50 variant).
