Product details
Overview
R5F111NGGLA#W0 from Renesas is an 85-pin VFLGA-packaged RL78/L1C 16-bit microcontroller without USB, featuring 128 KB flash, 10 KB RAM, integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (13-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 such as smart meters and portable medical devices.
For engineers reviewing the R5F111NGGLA#W0 datasheet, R5F111NGGLA#W0 pinout, R5F111NGGLA#W0 application, or R5F111NGGLA#W0 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), absence of USB peripheral, VFLGA-85 package compatibility with high-density PCB layouts, and verified support for LCD bias generation via internal capacitor-split method.
Technical Context
The R5F111NGGLA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz or 30.5 μs at 32.768 kHz). It integrates a 12-bit interval timer, real-time clock 2 (RTC2) with calendar and alarm, and event link controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its LCD controller supports internal voltage boosting and configurable segment/common drive (up to 44 segments × 4 commons), while the 12-bit A/D converter operates with internal reference (1.45 V TYP.) and includes temperature sensor input. Power management includes HALT, STOP, and SNOOZE modes, with LVD interrupt/reset selectable across 12 voltage levels.

What is the operating temperature grade of R5F111NGGLA#W0?
R5F111NGGLA#W0 is rated for industrial temperature operation from −40°C to +105°C, indicated by the "G" suffix in its orderable part number per Section 1.2 of R01DS0192EJ0240. This qualifies it for deployment in demanding environments such as utility metering, factory automation, and outdoor equipment.
How many analog input channels does the 12-bit A/D converter in R5F111NGGLA#W0 support?
The 12-bit A/D converter in R5F111NGGLA#W0 supports 13 analog input channels: ANI0 through ANI6 and ANI16 through ANI21. ANI0 and ANI1 double as AVREFP and AVREFM reference inputs, while ANI2–ANI6 and ANI16–ANI21 are dedicated analog inputs - confirmed in Section 1.1 "Features" and Table 1.2 "ROM, RAM capacities".
What package type and packaging specification does R5F111NGGLA#W0 use?
R5F111NGGLA#W0 uses an 85-pin plastic VFLGA package (7 mm × 7 mm, 0.65 mm pitch), with packaging specification #W0 indicating embossed tape carrier - as defined in Section 1.2 "Ordering Information" and Figure 1-1 of R01DS0192EJ0240.
