Overview
R5F111NGGLA#U0 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 (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 in industrial metering and portable instrumentation.
For engineers reviewing the R5F111NGGLA#U0 datasheet, R5F111NGGLA#U0 pinout, R5F111NGGLA#U0 application, or R5F111NGGLA#U0 equivalent, key selection criteria include its 85-pin VFLGA (7 × 7 mm) package, industrial-grade temperature range (−40 to +105°C), absence of USB functionality, and dedicated LCD voltage boosting circuitry supporting capacitor-split and external resistor division methods.
Technical Context
The R5F111NGGLA#U0 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 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 up to 44 segment and 4 common outputs using internal voltage boosting, while the analog subsystem includes two 8-bit D/A channels, two comparators with selectable reference sources, and background data flash rewriting (BGO) supporting 1 million write cycles at 1.8–3.6 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111NHGLA#U0 | 192 KB flash, 16 KB RAM, same 85-pin VFLGA package and peripheral set | Requires larger firmware image or future feature expansion; identical LCD/A/D/power specs | Select when firmware size exceeds 128 KB or long-term scalability is required |
| R5F110NGGLA#U0 | Same 128 KB flash/RAM but includes USB 2.0 function controller (full/low-speed) | Enables PC connectivity, firmware updates via USB, and BC1.2 charging detection | Choose only if USB host/device functionality is mandatory; adds UREGC/UVBUS/UDP/UDM pins and regulator overhead |
Compared with R5F111NGGLA#U0, R5F111NHGLA#U0 offers headroom for complex firmware without changing PCB layout, while R5F110NGGLA#U0 trades zero-USB simplicity for direct PC interface capability - neither is pin-compatible due to USB-specific pin additions and different internal regulator requirements.

FAQ
What is the maximum LCD segment count supported by the R5F111NGGLA#U0?
The R5F111NGGLA#U0 supports up to 44 segment outputs and 4 common outputs in its configured pin mapping. While the RL78/L1C family can drive up to 56 segments in 100-pin variants, the 85-pin R5F111NGGLA#U0 uses SEG0–SEG25, SEG27–SEG42, and SEG48–SEG55 - totaling 44 active segment lines - optimized for compact VFLGA packaging and industrial display requirements.
Does the R5F111NGGLA#U0 include USB functionality?
No, the R5F111NGGLA#U0 does not include USB functionality. Its part number prefix "R5F111" denotes the non-USB variant of the RL78/L1C family. USB-capable equivalents use "R5F110" (e.g., R5F110NGGLA#U0) and require additional pins (UREGC, UVBUS, UDP, UDM) and regulator circuitry not present on the R5F111NGGLA#U0.
What is the operating temperature range for the R5F111NGGLA#U0?
The R5F111NGGLA#U0 is rated for industrial operation from −40 to +105°C, as indicated by the "G" suffix in its ordering code. This extended range ensures reliable performance in demanding environments such as smart meters, factory HMIs, and appliance control panels where ambient temperatures exceed consumer-grade limits.
How much data flash memory is available on the R5F111NGGLA#U0?
The R5F111NGGLA#U0 includes 8 KB of data flash memory with background operation (BGO) support, enabling concurrent program execution and data rewriting. It guarantees 1,000,000 write cycles at VDD = 1.8–3.6 V, making it suitable for storing calibration coefficients, usage logs, or field-updated configuration parameters without requiring external EEPROM.
What package type and mounting footprint does the R5F111NGGLA#U0 use?
The R5F111NGGLA#U0 uses an 85-pin plastic VFLGA package measuring 7 × 7 mm with 0.65 mm pitch. Its land pattern follows JEDEC MO-220, requiring solder paste stencil design for bottom-termination components and X-ray inspection for void assessment - distinct from QFP packages and incompatible with standard SOIC or TSSOP footprints.
