Product details
Overview
R5F110NGGLA#W0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (44–56 segment, 4–8 common), 12-bit A/D converter (12-channel, VDD = 2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), and 96 KB flash memory. It operates from 1.6 V to 3.6 V and delivers 33 DMIPS at 24 MHz, targeting battery-powered LCD-based medical, home appliance, and industrial HMI devices.
For engineers reviewing the R5F110NGGLA#W0 datasheet, R5F110NGGLA#W0 pinout, R5F110NGGLA#W0 application, or R5F110NGGLA#W0 equivalent, key selection criteria include its VFLGA-85 package, industrial-grade temperature range (−40°C to +105°C), USB functionality, LCD drive capability, and true low-power operation down to 0.68 μA in RTC2+LVD mode.
Technical Context
The R5F110NGGLA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs min @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip high-speed oscillator (±1.0% accuracy), and event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Its LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods; it drives up to 56 segments and 8 commons with programmable bias and duty settings. The 12-bit A/D converter includes internal reference (1.45 V TYP) and temperature sensor, while the data flash enables background rewriting (1M write cycles) during program execution.

FAQ
What is the maximum LCD segment count supported by the R5F110NGGLA#W0?
The R5F110NGGLA#W0 supports up to 56 segment outputs and 8 common outputs, configurable for static, 1/2, 1/3, or 1/4 duty drive. The exact count depends on selected common count: 44 segments with 4 commons or 56 segments with 8 commons, as confirmed in the RL78/L1C datasheet Section 1.1 Features.
Does the R5F110NGGLA#W0 support USB device enumeration without external components?
Yes, the R5F110NGGLA#W0 includes an integrated USB 2.0 function controller with internal transceivers and voltage regulator. Only external 0.33 μF (UREGC–VSS) and 27 Ω series resistors on UDP/UDM are required for full-speed operation-no external PHY or level shifter is needed for basic USB device functionality.
What are the power consumption figures for R5F110NGGLA#W0 in STOP mode?
In STOP mode with RTC2 and LVD active, the R5F110NGGLA#W0 consumes 0.68 μA (typical) at VDD = 3.0 V and TA = 25°C. This value is specified in the RL78/L1C datasheet Section 1.1 Features and enables multi-year battery operation in always-on LCD applications.
Can the R5F110NGGLA#W0 perform A/D conversion while in low-power HALT mode?
No-the 12-bit A/D converter requires the system clock to be active and cannot operate in HALT mode. However, it can run in SNOOZE mode, where the CPU is halted but selected peripherals (including A/D) remain clocked and functional, enabling low-power periodic sampling.
Is the R5F110NGGLA#W0 pin-compatible with other RL78/L1C variants in the 85-pin VFLGA package?
Yes, all RL78/L1C 85-pin VFLGA variants-including R5F110NGGLA#W0, R5F110NHGLA#W0, and R5F111NGGLA#W0-share identical pinouts and package dimensions (PVLG0085JA-A). Functional differences (e.g., USB presence, flash size) do not affect physical compatibility or PCB layout.
