Renesas R5F10RGCGFB#V0

Overview

R5F10RGCGFB#V0 from Renesas is a 48-pin LFQFP, 32 KB flash, 2 KB data flash, 1.5 KB RAM RL78/L12 16-bit microcontroller with integrated LCD controller/driver (35 seg × 8 com), 10-bit ADC (10 channels), RTC, 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 R5F10RGCGFB#V0 datasheet, R5F10RGCGFB#V0 pinout, R5F10RGCGFB#V0 application, or R5F10RGCGFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, 32 KB code flash with self-programming, on-chip LCD drive supporting capacitor split and internal boost methods, and industrial-grade −40°C to +105°C operation.

Technical Context

The R5F10RGCGFB#V0 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 31 DMIPS at 24 MHz. It integrates a high-speed on-chip oscillator (±1% accuracy from 1.8–5.5 V, −20°C to 85°C) and supports multiple clock sources including external crystal (X1/X2) and subsystem clock (XT1/XT2).

Its peripheral set includes two CSI interfaces (SPI-compatible), one I²C, one UART, eight 16-bit timer channels, DMA (2 channels), 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#V0?

The R5F10RGCGFB#V0 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, with hardware multiply (16×16→32-bit) and MAC units enabling efficient signal processing in R5F10RGCGFB#V0-based metering firmware.

Does the R5F10RGCGFB#V0 support external crystal oscillators for real-time clock functionality?

Yes, the R5F10RGCGFB#V0 supports external 32.768 kHz crystals via XT1/XT2 pins for precision RTC operation. It also integrates a low-speed on-chip oscillator (15 kHz typical) for backup timing, and the RTC includes calendar, alarm, and watch correction functions - all operational in Halt mode at 0.64 µA.

How does the LCD controller in the R5F10RGCGFB#V0 reduce system-level design complexity?

The R5F10RGCGFB#V0 integrates a full LCD controller/driver supporting up to 35 segments × 8 commons. It eliminates need for external driver ICs by providing VL1–VL4 power rails, COM0–COM7 outputs, SEG0–SEG35 drivers, and configurable bias methods (capacitor split, internal boost, resistance division), significantly reducing BOM and layout effort in R5F10RGCGFB#V0-based displays.

What safety certifications or built-in diagnostics does the R5F10RGCGFB#V0 provide for industrial use?

The R5F10RGCGFB#V0 includes hardware-level safety features aligned with IEC/UL 60730 Class B requirements: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - all enabled without software overhead, critical for R5F10RGCGFB#V0 deployments in certified industrial equipment.

Can the R5F10RGCGFB#V0 operate from a single 1.6 V supply, and what peripherals remain functional at that voltage?

Yes, the R5F10RGCGFB#V0 supports 1.6 V to 5.5 V operation. At 1.6 V, the 10-bit ADC (with internal 1.45 V reference), RTC, LVD, and low-power modes (Stop/Halt) remain fully functional. The high-speed on-chip oscillator operates down to 1.8 V, so external clock or crystal sources are required for full 24 MHz operation below that threshold.
