Product details
Overview
R5F10RG8AFB#30 from Renesas is an 8 KB flash, 1.5 KB RAM, 48-pin LFQFP microcontroller in the RL78/L12 family, featuring integrated LCD controller/driver (up to 35 seg × 8 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 R5F10RG8AFB#30 datasheet, R5F10RG8AFB#30 pinout, R5F10RG8AFB#30 application, or R5F10RG8AFB#30 equivalent, key selection criteria include its 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch) package, 8 KB code flash with data flash (2 KB), 1.6–5.5 V supply range, and built-in LCD bias generation supporting capacitor-split and internal-boost methods.
Technical Context
The R5F10RG8AFB#30 implements the 16-bit RL78 CPU core delivering 31 DMIPS at 24 MHz, with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 cycles. Its on-chip high-speed oscillator achieves ±1% accuracy across 1.8–5.5 V and −20°C to +85°C.
It integrates a dedicated LCD controller supporting waveform types A/B, 16-step contrast adjustment, blinking control, and three bias methods - capacitor split (0.12 µA LCD current), internal voltage boost (0.63 µA at VDD = 3.0 V), and resistance division - enabling direct drive of segment-based displays without external components.

This performance level supports real-time LCD refresh, sensor polling, and basic communication protocols without external acceleration.
Does the R5F10RG8AFB#30 support LCD bias generation without external components?
Yes, the R5F10RG8AFB#30 integrates a full LCD controller/driver capable of generating bias voltages internally. It supports capacitor-split (0.12 µA LCD current), internal voltage boost (0.63 µA at 3.0 V), and external resistor-divider methods - eliminating the need for external bias ICs or charge pumps in most segment-LCD applications.
What low-power modes are available on the R5F10RG8AFB#30, and what is the lowest current draw?
The R5F10RG8AFB#30 offers Stop mode (0.23 µA RAM retained), Halt mode (0.64 µA with RTC + LVD active), and Snooze mode for partial peripheral operation. The lowest guaranteed current is 0.64 µA in Halt mode - critical for battery-powered devices requiring decade-long operation with calendar-aware wake-up capability.
How many ADC channels and what resolution does the R5F10RG8AFB#30 provide?
The R5F10RG8AFB#30 includes a 10-bit successive-approximation ADC with up to 10 input channels (ANI0–ANI23, configurable per package), 2.1 µs conversion time, and operation down to 1.6 V supply. It features an internal 1.45 V reference voltage, enabling accurate measurements independent of VDD fluctuations in battery-operated systems.
Is the R5F10RG8AFB#30 pin-compatible with other RL78/L12 variants in the 48-pin LFQFP package?
Yes, the R5F10RG8AFB#30 shares identical pinout and package (48-pin LFQFP, 0.5 mm pitch) with all other R5F10RGx variants including R5F10RGAAB#30 and R5F10RGCAF#30.
