Product details
Overview
R5F10RLAAFB#V0 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/L12 microcontroller with 16 KB flash, 2 KB data flash, 1 KB RAM, integrated LCD controller/driver (up to 39 seg × 8 com), and ultra-low-power operation (0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD display applications such as smart meters, thermostats, and portable medical devices.
For engineers reviewing the R5F10RLAAFB#V0 datasheet, R5F10RLAAFB#V0 pinout, R5F10RLAAFB#V0 application, or R5F10RLAAFB#V0 equivalent, key selection criteria include its 24 MHz max CPU frequency (31 DMIPS), on-chip 24 MHz ±1% oscillator, 10-bit ADC with 10 channels, 8-channel timer array, and IEC/UL 60730 safety features for functional safety compliance.
Technical Context
The R5F10RLAAFB#V0 implements a Harvard-architecture 16-bit RL78 CPU core with 3-stage pipeline, executing 86% of instructions 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 and ADC operation.
Its LCD controller supports three drive methods-capacitor split (0.12 µA), internal voltage boost (0.63 µA at 3.0 V), and resistance division-with programmable contrast (16 steps), blinking, and waveform A/B selection. The real-time clock includes full calendar, alarm, and watch correction functions.
