Product details
Overview
R5F10RLCGFA#50 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade (−40°C to +105°C) RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver supporting up to 39 seg × 4 com or 35 seg × 8 com, and ultra-low-power operation (0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD instrumentation such as smart meters and portable medical displays.
For engineers reviewing the R5F10RLCGFA#50 datasheet, R5F10RLCGFA#50 pinout, R5F10RLCGFA#50 application, or R5F10RLCGFA#50 equivalent, this page delivers verified electrical specs, confirmed LCD segment/com configuration, exact package mapping, validated low-power modes, and real-world design context for embedded LCD system integration.
Technical Context
The R5F10RLCGFA#50 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 dual power domains (VDD/EVDD, VSS/EVSS) and supports separate analog/digital ground routing to minimize noise in precision LCD biasing.
Its on-chip LCD controller supports three drive methods-capacitor split (0.12 µA), internal voltage boost (0.63 µA at VDD = 3.0 V), and resistance division-with 16-step contrast control, blinking, and waveform A/B selection. The device includes a dedicated 32.768 kHz subsystem clock (XT1/XT2) for RTC calendar accuracy and independent low-speed oscillator (15 kHz) for watchdog timing.
