Product details
Overview
R5F10RFAGFP#10 from Renesas is a 44-pin LQFP, 16 KB flash, 2 KB data flash, 1 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). It targets battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10RFAGFP#10 datasheet, R5F10RFAGFP#10 pinout, R5F10RFAGFP#10 application, or R5F10RFAGFP#10 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 method, and support for I²C, UART, and simplified SPI interfaces.
Technical Context
The R5F10RFAGFP#10 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It supports dual-clock domains: high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature) and subsystem clock (32.768 kHz crystal or low-speed internal oscillator).
Its integrated LCD controller supports three drive methods (capacitor split, internal boost, resistance division), 16-step contrast control, blinking, and waveform A/B selection. The peripheral set includes two DMA channels, window watchdog timer, interval timer, and safety features compliant with IEC/UL 60730 including CRC, RAM parity, and illegal access detection.

FAQ
What is the maximum operating frequency and power efficiency of the R5F10RFAGFP#10?
The R5F10RFAGFP#10 operates at up to 24 MHz using its high-speed on-chip oscillator (±1% accuracy), delivering 31 DMIPS. Its ultra-low-power design achieves 62.5 µA/MHz during active operation and only 0.64 µA in Halt mode with RTC and LVD enabled - making it ideal for long-life battery applications. This efficiency is validated in the R01DS0157EJ0223 datasheet Rev. 2.23.
Does the R5F10RFAGFP#10 support LCD drive without external components?
Yes, the R5F10RFAGFP#10 integrates a full LCD controller/driver supporting capacitor-split, internal voltage boost, and resistance-division methods. With capacitor-split drive, it achieves just 0.12 µA LCD operating current at VDD = 3.0 V. External components are limited to the REGC decoupling capacitor (0.47–1 µF) and optional VLx filtering caps - no external bias IC or charge pump is required.
What are the memory resources allocated in the R5F10RFAGFP#10?
The R5F10RFAGFP#10 contains 16 KB of on-chip code flash memory (with 1 KB block erase), 2 KB of data flash memory rated for 1 million erase cycles, and 1 KB of RAM with backup retention in all low-power modes. When self-programming and data flash functions are enabled, usable RAM is reduced to 630 bytes - a detail confirmed in the RL78/L12 datasheet Section 1.2.
Which communication interfaces does the R5F10RFAGFP#10 support?
The R5F10RFAGFP#10 supports UART (7-/8-/9-bit), up to two simplified SPI (CSI) channels, one I²C multi-master interface (IICA0), and LIN bus. All are implemented in hardware with dedicated registers and interrupt vectors. The UART and CSI modules share pins with LCD segments and key return functions, enabling flexible resource allocation per application needs.
Is the R5F10RFAGFP#10 qualified for industrial temperature operation?
Yes, the 'G' suffix in R5F10RFAGFP#10 denotes industrial temperature grade, with guaranteed operation from −40°C to +105°C. This rating is specified in the device ordering information (Figure 1-1) and validated across all electrical characteristics in the R01DS0157EJ0223 datasheet - including flash read/write, ADC accuracy, and LCD drive stability.
