Product details
Overview
R5F10RLAAFB#10 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 × 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 display applications such as smart meters, thermostats, and portable medical devices.
For engineers reviewing the R5F10RLAAFB#10 datasheet, R5F10RLAAFB#10 pinout, R5F10RLAAFB#10 application, or R5F10RLAAFB#10 equivalent, key selection criteria include its 24 MHz max CPU frequency (31 DMIPS), 10-bit ADC with 10 channels, on-chip high-speed oscillator (±1% accuracy), I²C/SPI/UART interfaces, and IEC/UL 60730 safety features for functional safety compliance.
Technical Context
The R5F10RLAAFB#10 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its low-power design integrates multiple sleep modes-Stop (0.23 µA), Halt (0.64 µA), and Snooze-with dedicated voltage regulator (REGC) and LCD power rails (VL1–VL4).
It embeds a full-featured LCD controller supporting capacitor-split, internal-boost, and resistor-division drive methods; real-time clock with calendar/alarm; 8-channel timer array; 2-channel DMA; and hardware CRC engine for flash integrity verification-enabling robust, self-monitoring embedded control in consumer-grade temperature range (−40°C to +85°C).
