Product details
Overview
R5F10RF8AFP#70 from Renesas is an 8 KB flash, 2 KB data flash, 1 KB RAM RL78/L12 16-bit microcontroller in 44-pin LQFP (10 × 10 mm, 0.8 mm pitch), featuring integrated LCD controller/driver (up to 39 seg × 4 com), 10-bit ADC (10 channels), RTC with calendar/alarm, 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 R5F10RF8AFP#70 datasheet, R5F10RF8AFP#70 pinout, R5F10RF8AFP#70 application, or R5F10RF8AFP#70 equivalent, key selection criteria include its 44-pin LQFP package, 8 KB code flash density, LCD drive capability with capacitor split/internal boost methods, 1.6–5.5 V supply range, and support for I²C, UART, and simplified SPI interfaces.
Technical Context
The R5F10RF8AFP#70 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 31 DMIPS at 24 MHz. Its on-chip high-speed oscillator delivers ±1% accuracy across 1.8–5.5 V and −20°C to +85°C, eliminating external crystal requirements for many applications.
It integrates a full-featured LCD controller supporting waveform types A/B, 16-step contrast adjustment, blinking control, and three drive methods-capacitor split (0.12 µA), internal voltage boost (0.63 µA at VDD = 3.0 V), and resistance division-enabling flexible low-power segment driving.

FAQ
What is the maximum operating frequency and core performance of the R5F10RF8AFP#70?
The R5F10RF8AFP#70 operates at up to 24 MHz using its on-chip high-speed oscillator and delivers 31 DMIPS of processing performance. Its RL78 16-bit CPU core executes 86% of instructions in 1–2 clock cycles, enabling efficient real-time control in LCD-centric applications without external clock components.
Does the R5F10RF8AFP#70 support LCD drive with internal voltage boosting?
Yes, the R5F10RF8AFP#70 supports LCD drive using the internal voltage boost method, consuming only 0.63 µA at VDD = 3.0 V. This eliminates the need for external charge pumps in low-power applications like portable meters and medical devices where component count and standby current are critical.
What low-power modes are available on the R5F10RF8AFP#70, and what is the lowest current draw?
The R5F10RF8AFP#70 supports Stop mode (0.23 µA, RAM retained), Halt mode (0.64 µA with RTC + LVD active), and Snooze mode for selective peripheral wake-up. The 0.64 µA Halt current enables decade-long battery life in applications requiring real-time clock functionality during sleep.
Can the R5F10RF8AFP#70 be used in industrial temperature ranges?
No - the R5F10RF8AFP#70 is rated for consumer-grade operation from −40°C to +85°C (suffix 'A'). For industrial applications requiring −40°C to +105°C, the equivalent part is R5F10RF8GFP#70 (same flash/RAM, 'G' suffix), which shares identical functionality and pinout but is qualified for extended temperature operation.
What communication interfaces does the R5F10RF8AFP#70 include?
The R5F10RF8AFP#70 includes one I²C interface (IICA0), one UART channel (UART0), two simplified SPI channels (CSI00/CSI01), and one LIN interface. All are fully functional in the 44-pin LQFP package and support simultaneous use with the integrated LCD controller and ADC.
