Renesas R5F10RGCAFB#V0

Overview

R5F10RGCAFB#V0 from Renesas is a 48-pin LFQFP, 32 KB flash, 2 KB data flash, 1.5 KB RAM RL78/L12 microcontroller with integrated LCD controller/driver (up to 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 R5F10RGCAFB#V0 datasheet, R5F10RGCAFB#V0 pinout, R5F10RGCAFB#V0 application, or R5F10RGCAFB#V0 equivalent, key selection criteria include its 48-pin 7 mm × 7 mm 0.5 mm pitch LFQFP package, 32 KB code flash with self-programming, on-chip LCD bias generation, and support for capacitor-split or internal-boost LCD drive methods.

Technical Context

The R5F10RGCAFB#V0 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 clock cycles. It integrates a high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature) and supports multiple clock sources including external crystals (X1/X2, XT1/XT2).

Its peripheral set includes two CSI interfaces (SPI-compatible), one I²C, one UART, up to eight 16-bit timer channels, DMA controller (2 channels), and safety features compliant with IEC/UL 60730 - including flash CRC, RAM parity, SFR write protection, and illegal memory access detection.

FAQ

What is the maximum operating frequency and performance of the R5F10RGCAFB#V0?

The R5F10RGCAFB#V0 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS. Its 16-bit RL78 core executes 86% of instructions in 1–2 clock cycles, and it supports multiply/accumulate operations in 1–2 cycles - enabling responsive real-time control in LCD-based systems without external acceleration.

Does the R5F10RGCAFB#V0 support external crystal oscillators, and what are the options?

Yes, the R5F10RGCAFB#V0 supports external crystals on X1/X2 (main system clock) and XT1/XT2 (subsystem clock). The main crystal operates at 1–20 MHz (depending on VDD), while the subsystem crystal runs at 32.768 kHz for RTC accuracy. These coexist with the internal 24 MHz oscillator, allowing seamless clock source switching for power/performance trade-offs.

How does the LCD controller in the R5F10RGCAFB#V0 reduce system BOM cost?

The R5F10RGCAFB#V0 integrates a full LCD controller/driver supporting up to 35 segments × 8 commons, three drive methods (capacitor split, internal boost, resistor division), and 16-step contrast control. This eliminates external LCD bias generators, level shifters, and driver ICs - reducing component count, PCB area, and assembly cost in display-centric designs.

What low-power modes are available on the R5F10RGCAFB#V0, and what functions remain active?

The R5F10RGCAFB#V0 offers Stop mode (0.23 µA RAM-retained), Halt mode (0.64 µA with RTC + LVD active), and Snooze mode. In Halt, the RTC maintains calendar/timekeeping, LVD monitors supply voltage, and wake-up interrupts (e.g., key press, timer) restore full operation - ideal for always-on display applications with infrequent interaction.

Is the R5F10RGCAFB#V0 qualified for industrial temperature range, and what grade does it carry?

No, the R5F10RGCAFB#V0 carries the 'A' suffix indicating Consumer grade qualification for −40°C to +85°C ambient operation. For industrial applications requiring −40°C to +105°C, Renesas offers the 'G' grade variant R5F10RGCGFB#V0 - identical functionality but qualified to extended temperature specifications.
