Product details
Overview
R5F10WLDAFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 48 KB flash, 1.5 KB RAM RL78/L13 microcontroller with integrated LCD controller/driver (36 segment / 4 common outputs), 9-channel 8/10-bit ADC, and ultra-low-power operation down to 71 μA/MHz - designed for battery-powered LCD-based consumer instrumentation including digital thermostats, portable medical monitors, and smart utility meters.
For engineers reviewing the R5F10WLDAFA#30 datasheet, R5F10WLDAFA#30 pinout, R5F10WLDAFA#30 application, or R5F10WLDAFA#30 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and two confirmed alternative parts - all grounded in Renesas' official R01DS0168EJ0232 Rev.2.32 specification.
Technical Context
The R5F10WLDAFA#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and 1 MB address space - operating at up to 24 MHz using its high-accuracy ±1.0% on-chip oscillator (selectable 1–24 MHz). It integrates a dedicated 16-bit timer KB20 for PWM output and supports RTC2 with calendar, alarm, and clock correction functions.
Its power architecture includes HALT, STOP, and SNOOZE modes, enabling true low-power operation: 0.61 μA in RTC+LVD active mode and full 1.6–5.5 V supply range compatibility. The device features dual comparator inputs (IVCMP0/IVCMP1), programmable key interrupt (KR0–KR7), and remote carrier output (REMOOUT) for IR control applications.
