Product details
Overview
R5F10RF8GFP#10 from Renesas is an 8 KB flash, 1.5 KB RAM, 44-pin LQFP microcontroller in the RL78/L12 family, featuring integrated LCD controller/driver (up to 39 seg × 4 com), 10-bit ADC (10 channels), RTC with calendar/alarm, and ultra-low-power operation (0.64 µA in Halt mode with RTC + LVD). It targets battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10RF8GFP#10 datasheet, R5F10RF8GFP#10 pinout, R5F10RF8GFP#10 application, or R5F10RF8GFP#10 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip voltage regulator support for LCD bias (VL1–VL4), 24 MHz high-speed on-chip oscillator (±1% accuracy), and dual communication interfaces (I²C + UART + CSI).
Technical Context
The R5F10RF8GFP#10 implements the 16-bit RL78 CPU core with Harvard architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its instruction set includes single-cycle 16×16 multiply and MAC operations, plus barrel shift, enabling efficient signal processing in resource-constrained LCD applications.
It integrates a dedicated LCD controller supporting capacitor split, internal boost, and resistance division drive methods, with programmable contrast (16 steps), blinking control, and waveform A/B selection. The real-time clock includes full calendar, alarm, and watch correction functions-operating independently in Halt mode with only 0.64 µA consumption.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10RG8GFB#10 | 48-pin LFQFP, same 8 KB flash/1.5 KB RAM, but adds 4 extra GPIO and ANI22/23 - no change in LCD capability or power specs | Requires PCB redesign due to different footprint (7×7 mm, 0.5 mm pitch vs. 10×10 mm, 0.8 mm pitch) | Select when additional analog inputs or GPIO are needed without increasing flash/RAM |
| R5F10RJ8GFA#10 | 52-pin LQFP, same memory and peripherals, adds TI05/TO05, ANI23, and 4 more segment outputs - retains identical LCD drive architecture | Enables larger 30-seg × 8-com displays; requires larger PCB area and different pin layout | Choose for higher-resolution LCDs where 44-pin I/O count is limiting but same low-power profile is required |
Compared with R5F10RF8GFP#10, the R5F10RG8GFB#10 offers pin-compatible peripheral functionality in a smaller 48-pin package but trades off some LCD segment count flexibility, while R5F10RJ8GFA#10 expands segment drive capacity at the cost of increased board area and routing complexity.

FAQ
What is the maximum operating frequency and power consumption of the R5F10RF8GFP#10?
The R5F10RF8GFP#10 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS. In active mode, it consumes 62.5 µA per MHz; in Halt mode with RTC and LVD enabled, it draws just 0.64 µA - verified per Renesas datasheet R01DS0157EJ0223 Rev.2.23. This makes R5F10RF8GFP#10 ideal for energy-sensitive applications like utility meters.
Does the R5F10RF8GFP#10 support external crystal oscillators?
Yes, the R5F10RF8GFP#10 supports both main and subsystem crystal oscillators: X1/X2 pins accept 1–20 MHz crystals for the main system clock, and XT1/XT2 pins accept 32.768 kHz crystals for independent RTC operation. These can be used simultaneously with the on-chip oscillator, and the R5F10RF8GFP#10 automatically switches between sources based on configuration registers.
How many LCD segments and commons does the R5F10RF8GFP#10 support?
The R5F10RF8GFP#10 supports up to 39 segment outputs and 4 common outputs (39 seg × 4 com) or 35 segment outputs and 8 common outputs (35 seg × 8 com), as confirmed in the RL78/L12 datasheet Section 1.1. Its 44-pin LQFP package routes COM0–COM3 and SEG0–SEG34, matching the 39×4 configuration. The R5F10RF8GFP#10 does not support COM4–COM7 in this package variant.
What safety features does the R5F10RF8GFP#10 include for IEC 60730 compliance?
The R5F10RF8GFP#10 includes flash memory CRC calculation, RAM parity error checking, RAM write protection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - all documented in Section 1.1 of the datasheet. These features enable R5F10RF8GFP#10 to meet Class B requirements of IEC/UL 60730 for household and similar appliances without external supervision circuitry.
Can the R5F10RF8GFP#10 operate from a 1.6 V supply?
Yes, the R5F10RF8GFP#10 supports 1.6 V to 5.5 V single-supply operation across its full temperature range (−40°C to +105°C), including all core functions, LCD driving (capacitor split method), and ADC measurements. At 1.6 V, maximum operating frequency is limited to 4 MHz (LV mode), and the 10-bit ADC remains functional with internal 1.45 V reference - confirmed in Section 1.1 "Ultra-Low Power Technology" of the datasheet.
