Renesas R5F10RGCGFB#30

Overview

R5F10RGCGFB#30 from Renesas is a 48-pin LFQFP, industrial-grade (−40°C to +105°C) 16-bit RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver (up to 35 seg × 8 com), and ultra-low-power operation (62.5 µA/MHz active, 0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD display systems such as smart meters and portable medical devices.

For engineers reviewing the R5F10RGCGFB#30 datasheet, R5F10RGCGFB#30 pinout, R5F10RGCGFB#30 application, or R5F10RGCGFB#30 equivalent, key selection criteria include its 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch) package, on-chip LCD drive capability with capacitor-split and internal-boost methods, 10-bit ADC (10 channels), and support for I²C, UART, and simplified SPI interfaces.

Technical Context

The R5F10RGCGFB#30 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, delivering 31 DMIPS at 24 MHz using its high-speed on-chip oscillator (±1% accuracy from 1.8 V to 5.5 V). It integrates a dedicated LCD controller supporting waveform types A/B, 16-step contrast adjustment, and blinking control.

Its peripheral set includes an 8-channel timer array unit with RTC (full calendar + alarm + watch correction), 2-channel DMA, 12-bit interval timer, windowed watchdog timer, and safety features compliant with IEC/UL 60730 - including flash CRC, RAM parity check, SFR write protection, and illegal memory access detection.

FAQ

What is the maximum operating frequency and core performance of the R5F10RGCGFB#30?

The R5F10RGCGFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator and delivers 31 DMIPS. Its RL78 16-bit CPU core executes 86% of instructions in 1–2 clock cycles and includes hardware multiply/accumulate (MAC) and barrel shifter units - enabling efficient signal processing in resource-constrained LCD applications.

Does the R5F10RGCGFB#30 support external crystals, and what clock options are available?

Yes, the R5F10RGCGFB#30 supports external crystals on X1/X2 (main system clock) and XT1/XT2 (subsystem clock, 32.768 kHz). It also includes a factory-trimmed high-speed on-chip oscillator (24 MHz ±1%) and low-speed on-chip oscillator (15 kHz), allowing flexible clock source selection - including crystal-free operation for cost-sensitive designs.

How does the R5F10RGCGFB#30 manage LCD biasing, and what methods are supported?

The R5F10RGCGFB#30 supports three LCD biasing methods: capacitor-split (requiring external CAPL/CAPH), internal voltage boost (using VL1–VL4), and external resistor division. This flexibility allows optimization for power, contrast, and component count - e.g., capacitor-split achieves just 0.12 µA LCD current, ideal for battery longevity.

What safety features does the R5F10RGCGFB#30 include for IEC/UL 60730 compliance?

The R5F10RGCGFB#30 includes flash memory CRC calculation, RAM parity error detection, RAM/SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - all hardware-accelerated features required for Class B compliance in household and industrial appliances.

Is the R5F10RGCGFB#30 pin-compatible with other RL78/L12 variants in the same package?

Yes, all RL78/L12 devices in the 48-pin LFQFP package (e.g., R5F10RGxGFB#30 series) share identical pinouts and electrical characteristics - enabling seamless migration between memory configurations (8/16/32 KB flash) and temperature grades without PCB redesign.
