Product details
Overview
R5F10RFCGFP#30 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 (up to 39 seg × 4 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 such as smart meters and portable medical devices.
For engineers reviewing the R5F10RFCGFP#30 datasheet, R5F10RFCGFP#30 pinout, R5F10RFCGFP#30 application, or R5F10RFCGFP#30 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 with capacitor-split and internal-boost methods, and support for I²C, UART, and simplified SPI interfaces.
Technical Context
The R5F10RFCGFP#30 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 low-speed subsystem clock (32.768 kHz crystal support) for independent RTC operation.
Its LCD controller supports three drive methods (capacitor split, internal voltage boost, resistance division), waveform A/B selection, 16-step contrast control, and blinking - all configurable without external components. The peripheral set includes two DMA channels, window watchdog timer, and safety features compliant with IEC/UL 60730 including flash CRC, RAM parity, and illegal memory access detection.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10RFAAGFP#30 | 16 KB flash, same 44-pin LQFP package, identical peripherals and pinout | Lower memory capacity suits simpler UIs with fewer display states or smaller firmware footprints | Select when firmware size < 14 KB and cost sensitivity outweighs future scalability needs |
| R5F10RGCGFB#30 | 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch), 32 KB flash, adds 4 extra I/O and 2 additional ADC channels | Higher pin count supports expanded keypad matrix or additional sensors without external logic | Choose when requiring >40 GPIO or dual-sensor analog acquisition; requires PCB redesign |

FAQ
What is the operating temperature range for the R5F10RFCGFP#30?
The R5F10RFCGFP#30 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in the part number. This extended range supports deployment in harsh environments such as utility meter enclosures, factory automation panels, and outdoor medical equipment housings where ambient temperatures exceed consumer-grade limits.
Does the R5F10RFCGFP#30 require an external crystal for real-time clock functionality?
No. The R5F10RFCGFP#30 supports RTC operation using either an external 32.768 kHz crystal (XT1/XT2 pins) or the internal low-speed oscillator. When using the external crystal, the RTC maintains high accuracy; the internal oscillator provides sufficient timing for non-critical calendar functions while eliminating BOM cost and board space.
How many LCD segments can the R5F10RFCGFP#30 drive, and what drive methods are supported?
The R5F10RFCGFP#30 drives up to 35 segments × 8 commons or 39 segments × 4 commons. It supports three LCD drive methods: capacitor-split (requiring external capacitors), internal voltage boost (integrated charge pump), and resistance division (external resistor network). Method selection is software-configurable per application requirements.
What debug interface does the R5F10RFCGFP#30 provide, and how is it accessed?
The R5F10RFCGFP#30 includes a 1-wire on-chip debug interface accessed via TOOL0 (P40), TOOLTxD (P12), and TOOLRxD (P11) pins. This interface enables full-featured debugging - including breakpoints, register inspection, and flash programming - using Renesas E2 studio and compatible debug probes without requiring JTAG header space.
Is the R5F10RFCGFP#30 pin-compatible with other RL78/L12 variants in the 44-pin LQFP package?
Yes. All RL78/L12 44-pin LQFP variants - including R5F10RF8GFP#30, R5F10RFAAGFP#30, and R5F10RFCGFP#30 - share identical pinouts and electrical characteristics. Firmware and hardware designs are interchangeable across these parts, allowing seamless migration from 8 KB to 32 KB flash based on feature requirements.
