Product details
Overview
R5F10RLCAFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch) 16-bit RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver (up to 39 seg × 4 com), and ultra-low-power operation (0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD display systems such as smart meters, thermostats, and portable medical devices.
For engineers reviewing the R5F10RLCAFA#30 datasheet, R5F10RLCAFA#30 pinout, R5F10RLCAFA#30 application, or R5F10RLCAFA#30 equivalent, key selection criteria include its 24 MHz high-speed on-chip oscillator (±1% accuracy), 10-bit ADC with 1.6 V support, 8-channel timer array, I²C/SPI/UART interfaces, and IEC 60730-compliant safety features for Class B appliance control.
Technical Context
The R5F10RLCAFA#30 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its CPU supports single-cycle 16×16 multiply and MAC operations, 16-bit barrel shift, and 1-wire on-chip debug.
It integrates a dedicated LCD controller supporting capacitor split, internal voltage boost, and resistance division drive methods; real-time clock with full calendar/alarm; 2-channel DMA; and dual power domains (VDD/EVDD, VSS/EVSS) for noise-sensitive analog/LCD operation.
