Product details
Overview
R5F111NHGLA#W0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller without USB, featuring 128 KB flash, 12 KB RAM, integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (12-channel), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD-based consumer and industrial instrumentation.
For engineers reviewing the R5F111NHGLA#W0 datasheet, R5F111NHGLA#W0 pinout, R5F111NHGLA#W0 application, or R5F111NHGLA#W0 equivalent, key selection criteria include its VFLGA-85 package, -40°C to +105°C industrial temperature grade (G suffix), absence of USB PHY, and dedicated LCD voltage boosting circuitry with CAPH/CAPL terminals.
Technical Context
The R5F111NHGLA#W0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 μs (@24 MHz) to 30.5 μs (@32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB on-chip RAM.
Peripheral integration centers on LCD control (capacitor-split or external resistor division method), dual 8-bit D/A converters, two comparators with selectable reference sources, and a full suite of serial interfaces: four UART/LIN channels, five I²C channels, and four CSI (SPI-compatible) channels - all managed via Event Link Controller (ELC) and Data Transfer Controller (DTC).
Key Specifications

What are the key power modes and their typical current consumption for the R5F111NHGLA#W0?
The R5F111NHGLA#W0 supports HALT, STOP, and SNOOZE modes. STOP mode draws 0.68 μA (RTC2 + LVD active), HALT mode consumes 112.5 μA/MHz, and SNOOZE enables peripheral operation with CPU halted. These values are measured at VDD = 3.0 V, TA = 25°C, and are specified in the datasheet Section 1.1 "Ultra-low power consumption technology".
Which analog-to-digital converter resolution and input channels are available on the R5F111NHGLA#W0?
The R5F111NHGLA#W0 features an 8/10-bit A/D converter at VDD = 1.6–3.6 V and a 12-bit A/D converter at VDD = 2.4–3.6 V, with 12 analog input channels (ANI0–ANI6, ANI16–ANI21). Internal references include 1.45 V (TYP.) and a temperature sensor, as detailed in Section 1.1 "A/D converter".
What is the operating temperature range and industrial qualification status of the R5F111NHGLA#W0?
The R5F111NHGLA#W0 is rated for -40°C to +105°C ambient operation (industrial grade "G" suffix), qualified per Renesas' industrial reliability standards. This range is explicitly defined in Section 1.1 "Operating ambient temperature" and applies to all "G"-suffixed RL78/L1C devices including R5F111NHGLA#W0.
