Product details
Overview
R5F111NHALA#W0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller without USB, featuring 192 KB flash, 12 KB RAM, integrated LCD controller/driver (44/56 segment × 4/8 common), 12-bit A/D converter (12-channel, 2.4–3.6 V range), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD display systems in consumer electronics.
For engineers reviewing the R5F111NHALA#W0 datasheet, R5F111NHALA#W0 pinout, R5F111NHALA#W0 application, or R5F111NHALA#W0 equivalent, key selection criteria include LCD segment drive capability, low-power real-time clock support, analog input channel count, and VFLGA-85 package compatibility with space-constrained PCB layouts.
Technical Context
The R5F111NHALA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods.
Its analog subsystem includes a 12-bit A/D converter with internal reference (1.45 V TYP) and temperature sensor, dual 8-bit D/A outputs, two comparators with window/high-speed/low-speed modes, and independent AVDD/AVSS rails. Power management supports HALT, STOP, and SNOOZE modes with on-chip LVD and POR.
