Renesas R5F10RF8GFP#30

Overview

R5F10RF8GFP#30 from Renesas is an 8 KB flash, 2 KB data flash, 1 KB RAM RL78/L12 16-bit microcontroller in 44-pin LQFP (10 × 10 mm, 0.8 mm pitch), 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#30 datasheet, R5F10RF8GFP#30 pinout, R5F10RF8GFP#30 application, or R5F10RF8GFP#30 equivalent, key selection criteria include its 44-pin LQFP industrial-grade (-40°C to +105°C) package, on-chip LCD drive capability, 24 MHz max CPU frequency delivering 31 DMIPS, and support for capacitor-split and internal-boost LCD bias methods.

Technical Context

The R5F10RF8GFP#30 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its low-power design integrates a high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature), low-speed oscillator (15 kHz), and subsystem clock (32.768 kHz crystal support).

It embeds dedicated hardware for LCD control-including segment/common drivers, contrast adjustment (16 steps), blinking, and waveform A/B selection-and supports background data flash operations with 1 million erase cycles, enabling robust firmware updates in field-deployed devices.

FAQ

What is the maximum operating frequency and performance of the R5F10RF8GFP#30?

The R5F10RF8GFP#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. Its RL78 16-bit core executes 86% of instructions in just 1–2 clock cycles, enabling responsive real-time control in LCD-driven applications without external acceleration.

Does the R5F10RF8GFP#30 support LCD biasing without external components?

Yes, the R5F10RF8GFP#30 integrates dual LCD bias methods: capacitor-split and internal voltage boost. With appropriate external capacitors (CAPL/CAPH), it generates required LCD voltages internally-eliminating need for external charge pumps or resistor networks in most segmented display designs.

What low-power modes are available on the R5F10RF8GFP#30, and what is the lowest current draw?

The R5F10RF8GFP#30 supports Stop mode (0.23 µA RAM retained), Halt mode (0.64 µA with RTC + LVD active), and Snooze mode. The 0.64 µA Halt current enables multi-year battery operation in utility meters and portable instruments where continuous timekeeping is essential.

How many analog input channels and what resolution does the ADC in R5F10RF8GFP#30 provide?

The R5F10RF8GFP#30 features a 10-bit successive-approximation ADC with 10 input channels, 2.1 µs conversion time, and operation down to 1.6 V supply. It includes internal 1.45 V reference and supports analog inputs up to AVREFP, making it suitable for precision sensor interfacing in industrial and medical devices.

Is the R5F10RF8GFP#30 pin-compatible with other RL78/L12 variants like R5F10RG8GFB#30?

No, the R5F10RF8GFP#30 (44-pin LQFP) is not pin-compatible with R5F10RG8GFB#30 (48-pin LFQFP) due to different pin counts, pitch (0.8 mm vs. 0.5 mm), and physical dimensions. While both share identical peripheral sets and instruction set, PCB redesign is required for substitution-verify mechanical and thermal constraints before migration.
