Product details
Overview
R5F10NPLDFB#30 from Renesas is a 100-pin LFQFP ultra-low-power 16-bit RL78/I1C microcontroller with 512 KB code flash (dual-bank), 2 KB data flash, 32 KB RAM, hardware AES encryption, and a 24-bit ΔΣ A/D converter - designed for precision metrology in electric/gas/water metering systems requiring secure firmware updates and long-term battery operation.
For engineers reviewing the R5F10NPLDFB#30 datasheet, R5F10NPLDFB#30 pinout, R5F10NPLDFB#30 application, or R5F10NPLDFB#30 equivalent, key selection considerations include its independent-power-supply RTC (–40°C to +85°C), 32-bit multiply-accumulator, SNOOZE/STOP/HALT low-power modes, and dual UARTMG interfaces for pulse counting and communication in utility meter firmware stacks.
Technical Context
The R5F10NPLDFB#30 integrates an RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz PLL). It supports bank-switched flash programming for live firmware updates without halting execution.
Its analog subsystem includes four 24-bit ΔΣ ADC channels (SNDR ≥65 dB at ×32 gain) and six 12-bit SAR ADC channels with simultaneous sample-and-hold across three inputs - all referenced to selectable internal voltages (1.5/2.0/2.5 V) and powered by dedicated AVDD/AVSS rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power metrology MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10NMLDFB#30 | 80-pin LFQFP variant with identical core, flash, RAM, and peripherals but only 3 ΔΣ ADC channels and 4 SAR ADC channels | Suitable for cost-sensitive single-phase electricity meters with reduced channel count requirements | Select when PCB space and analog channel count allow reduction from 100-pin to 80-pin layout |
| RL78/G1M | Same RL78 core but lacks hardware AES, independent-power RTC, and ΔΣ ADC; offers 128–256 KB flash and lower pin count (64-pin) | Targeted at basic utility control nodes without cryptographic or high-resolution metrology needs | Choose for non-secure, lower-precision sensing where AES and 24-bit ADC are unnecessary |
Compared with R5F10NMLDFB#30 and RL78/G1M, the R5F10NPLDFB#30 uniquely delivers full 4-channel ΔΣ ADC capability, hardware AES acceleration, and 100-pin I/O flexibility - making it the only option among the three qualified for Class 0.2S electricity meter certification and secure firmware lifecycle management.

FAQ
What is the maximum operating frequency of the R5F10NPLDFB#30 CPU core?
The R5F10NPLDFB#30 supports a maximum CPU clock of 32 MHz via its integrated PLL, with minimum instruction execution time of 0.03125 µs. This frequency is fully compatible with the 24-bit ΔΣ A/D converter, enabling high-resolution sampling at up to 3.906 kHz while maintaining real-time processing headroom for AES encryption and RTC operations.
Does the R5F10NPLDFB#30 support secure firmware updates in the field?
Yes, the R5F10NPLDFB#30 supports secure field updates via its dual-bank 512 KB flash memory and hardware AES engine. The bank programming function allows one bank to run active firmware while the other is rewritten with signed, encrypted images - ensuring uninterrupted operation and cryptographic integrity verification before activation.
How many analog input channels does the R5F10NPLDFB#30 provide for metrology applications?
The R5F10NPLDFB#30 provides four 24-bit ΔΣ A/D converter channels and six 12-bit SAR A/D converter channels, with simultaneous sample-and-hold across three inputs. This configuration supports multi-sensor metering architectures such as polyphase electricity meters requiring differential voltage/current measurements.
What low-power modes are available on the R5F10NPLDFB#30 for battery-operated meters?
The R5F10NPLDFB#30 offers HALT (0.52 µA), STOP (0.39 µA), and SNOOZE (1.2 µA with RTC active) modes at 3.0 V. In SNOOZE mode, the independent-power-supply RTC continues timekeeping and can wake the CPU on alarm - enabling decade-long battery life in gas and water meters.
Is the R5F10NPLDFB#30 pin-compatible with other RL78/I1C variants?
No, the R5F10NPLDFB#30 is a 100-pin LFQFP device and is not pin-compatible with the 80-pin R5F10NMLDFB#30. While both share identical core architecture and peripheral sets, the 100-pin package adds additional I/O, ADC channels, and serial interfaces - requiring distinct PCB layout and routing.
