Product details
Overview
R5F10NPGDFB#30 from Renesas is a 100-pin LFQFP RL78/I1C microcontroller designed for electric AMI power meter applications. It integrates 128 KB flash, 8 KB RAM, 2 KB data flash, hardware AES encryption, independent-power-supply RTC, and 24-bit ΔΣ A/D converter with four channels - all operating from 1.9 V to 5.5 V across –40°C to +85°C.
For engineers reviewing the R5F10NPGDFB#30 datasheet, R5F10NPGDFB#30 pinout, R5F10NPGDFB#30 application, or R5F10NPGDFB#30 equivalent, this MCU delivers ultra-low-power operation (HALT/STOP/SNOOZE modes), on-chip debug, self-programming with boot swap, and LCD controller support up to 42 segments - critical for secure, battery-backed smart metering systems.
Technical Context
The R5F10NPGDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing from 0.03125 µs (32 MHz PLL) to 66.6 µs (15 kHz low-speed oscillator). It supports 16-bit multiplication, 16-bit MAC, and 32-bit division, with 1 MB address space and four banks of 8-bit general-purpose registers.
Its peripheral set includes UART0–UART3 (with IrDA and LIN support), I²C/Simplified I²C (up to 3 channels), CSI (3 channels), 8-channel 16-bit timer array, 12-bit interval timer, 4× 8-bit interval timers, independent RTC with calendar/alarm/correction, and event link controller (ELC) for 22-event signal routing - all optimized for deterministic real-time metering firmware execution.

The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NPJDFB#30 | 256 KB flash, 16 KB RAM, same 100-pin LFQFP package and peripheral set | Supports larger firmware images (e.g., dual-application OTA, advanced analytics) | Select when future firmware expansion or additional security features require more memory headroom |
| R5F10NMJDFB#30 | 80-pin LFQFP, 256 KB flash, 8 KB RAM, no hardware AES, reduced LCD segment count (34 vs. 42) | Suitable for cost-sensitive meters without encryption or full-display requirements | Choose for simplified meter designs where AES and 42-segment LCD are unnecessary - lowers PCB cost and layout complexity |
Compared with R5F10NPGDFB#30, R5F10NPJDFB#30 offers double flash/RAM for complex firmware but shares identical security and metrology capabilities, while R5F10NMJDFB#30 trades AES and display capacity for lower pin count and cost - making it viable only where those features are omitted from the system architecture.

Does the R5F10NPGDFB#30 include hardware AES acceleration?
Yes, the R5F10NPGDFB#30 includes a dedicated hardware AES circuit supporting GCM, ECB, and CBC cipher modes with 128-, 192-, and 256-bit key lengths. This feature is confirmed in the datasheet's "Outline of Functions" table and applies specifically to R5F10N-series parts - enabling secure firmware updates and encrypted data transmission without CPU resource consumption.
How many LCD segments can the R5F10NPGDFB#30 drive?
The R5F10NPGDFB#30 supports up to 42 segment signal outputs (SEG0–SEG41) and 8 common signal outputs (COM0–COM7), as specified in the 100-pin product block diagram and pin configuration. This matches the maximum LCD drive capability documented for 100-pin RL78/I1C variants and enables full-feature alphanumeric displays in smart meters.
What is the data flash endurance specification for the R5F10NPGDFB#30?
The R5F10NPGDFB#30 specifies 1,000,000 write/erase cycles (typical) for its 2 KB data flash memory. This endurance rating is guaranteed across the full operating voltage range (1.9 V to 5.5 V) and enables reliable long-term storage of metering logs, calibration data, and security keys without premature wear-out.
Is the R5F10NPGDFB#30 qualified for industrial temperature range?
Yes, the R5F10NPGDFB#30 is rated for industrial ambient temperature operation from –40°C to +85°C, as indicated by the "D" suffix in its part number (R5F10NPGDFB#30).
