Renesas R5F10RFCGFP#V0

Overview

R5F10RFCGFP#V0 from Renesas is a 44-pin LQFP, 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) for battery-powered LCD display systems.

For engineers reviewing the R5F10RFCGFP#V0 datasheet, R5F10RFCGFP#V0 pinout, R5F10RFCGFP#V0 application, or R5F10RFCGFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, industrial-grade −40°C to +105°C operation, on-chip LCD drive capability up to 280 segments, and support for capacitor-split or internal-boost LCD biasing methods.

Technical Context

The R5F10RFCGFP#V0 implements the RL78 CPU core 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) and subsystem clocks (XT1/XT2).

Its peripheral set includes UART, two CSI interfaces (SPI-compatible), I²C, DMA (2 channels), 8-channel 16-bit timer array, and an LCD controller supporting waveform types A/B, contrast adjustment (16 steps), and blinking-configured via dedicated segment/common pins and VLx/CAPL/CAPH power rails.

FAQ

What is the maximum LCD segment count supported by the R5F10RFCGFP#V0?

The R5F10RFCGFP#V0 supports up to 35 segment outputs and 8 common outputs, enabling configurations such as 35 × 8 (280 segments) or 39 × 4 (156 segments). This is implemented via dedicated SEG0–SEG34 and COM0–COM7 pins, with flexible waveform type A/B selection and 16-step contrast adjustment-all managed by the on-chip LCD controller without external components.

Does the R5F10RFCGFP#V0 include hardware support for functional safety standards?

Yes, the R5F10RFCGFP#V0 includes multiple hardware safety features aligned with IEC/UL 60730 requirements: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test capability-enabling Class B compliance in household and industrial appliances.

What are the power supply requirements for the LCD bias circuitry on the R5F10RFCGFP#V0?

The R5F10RFCGFP#V0 requires four dedicated LCD power pins: VL1–VL4 for segment voltage levels, plus CAPL and CAPH for the internal charge pump capacitor connections. For internal voltage boost operation at VDD = 3.0 V, typical LCD current is 0.63 µA; capacitor values must be 0.47–1.0 µF between CAPL/CAPH and VSS per the datasheet recommendation.

Can the R5F10RFCGFP#V0 operate without an external crystal?

Yes, the R5F10RFCGFP#V0 can operate fully from its high-speed on-chip oscillator (24 MHz ±1% over voltage and temperature), eliminating the need for external crystals in most applications. External crystals (X1/X2 or XT1/XT2) are optional and used only when higher timing precision or subsystem clocking (e.g., 32.768 kHz RTC) is required.

How many analog input channels does the R5F10RFCGFP#V0 provide, and what is their resolution?

The R5F10RFCGFP#V0 provides 10 analog input channels with 10-bit resolution and a 2.1 µs conversion time. Inputs include ANI0–ANI1 (on P20/P21), ANI16–ANI21 (on P41, P120, P142–P143), and support operation down to 1.6 V supply-making it suitable for low-voltage sensor interfaces in portable equipment.
