Product details
Overview
R5F111NFGLA#W0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller without USB, featuring 64 KB Flash, 8 KB Data Flash, 8 KB RAM, integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (13-channel), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD display systems in industrial temperature range (−40°C to +105°C).
For engineers reviewing the R5F111NFGLA#W0 datasheet, R5F111NFGLA#W0 pinout, R5F111NFGLA#W0 application, or R5F111NFGLA#W0 equivalent, key selection criteria include its VFLGA-85 package footprint, absence of USB PHY, industrial-grade thermal rating, LCD segment drive capability, and compatibility with Renesas' RL78 toolchain and IAR/CC-RL compilers.
Technical Context
The R5F111NFGLA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @ 24 MHz or 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) for peripheral synchronization.
Its analog subsystem includes dual 8-bit D/A outputs, two comparators (one with window mode), internal reference voltage (1.45 V TYP), and temperature sensor. Power management supports HALT, STOP, and SNOOZE modes, with on-chip POR and 12-level LVD for robust reset and monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111NGGLA#W0 | 128 KB Flash, 12 KB RAM, same VFLGA-85 package and peripheral set | Supports larger firmware (e.g., enhanced UI logic or protocol stacks) without layout change | Select when future firmware expansion or added features (e.g., BLE host stack) require more code space |
| R5F110NFGLA#W0 | Includes USB 2.0 function controller, identical Flash/RAM/package but adds UDM/UDP/UVBUS/UREGC pins | Enables direct USB-CDC communication for PC-based configuration or diagnostics | Choose only if USB connectivity is mandatory; requires routing USB differential pair and ESD protection |
Compared with R5F111NFGLA#W0, R5F111NGGLA#W0 offers scalable memory headroom within identical thermal and footprint constraints, while R5F110NFGLA#W0 trades off USB PHY integration - adding interface capability at the cost of increased layout complexity and no power advantage in non-USB use cases.

FAQ
Does R5F111NFGLA#W0 include USB functionality?
No, R5F111NFGLA#W0 is explicitly a USB-free variant of the RL78/L1C family. Its part number prefix "111" denotes no USB, and the datasheet block diagram, pin listing (no UDM/UDP/UVBUS signals), and ordering table confirm USB is omitted. Use R5F110NFGLA#W0 for USB-enabled versions.
What is the maximum LCD segment count supported by R5F111NFGLA#W0?
R5F111NFGLA#W0 supports up to 44 segment outputs and 4 common outputs (COM0–COM3) in its 85-pin VFLGA configuration. Segment allocation follows defined groupings (e.g., SEG0–SEG6, SEG12–SEG25), not all 56 segments listed for 100-pin variants - confirmed in Section 1.3.4 and Figure 1-1 of the datasheet.
Can R5F111NFGLA#W0 operate from a single 1.8 V supply?
Yes, R5F111NFGLA#W0 operates across 1.6 V to 3.6 V, so 1.8 V is fully supported. However, 12-bit A/D conversion requires VDD ≥ 2.4 V per datasheet specification; at 1.8 V, only 8/10-bit A/D mode is functional. Core execution, LCD drive, and timers remain operational.
Is the R5F111NFGLA#W0 pinout compatible with other RL78/L1C VFLGA-85 parts?
Yes, all RL78/L1C 85-pin VFLGA variants (e.g., R5F111NEALA, R5F111NFGLA#W0, R5F111NGGLA#W0) share identical mechanical pinout and electrical pin functions. Differences are limited to memory size and enabled peripherals - verified in Sections 1.3.3 and 1.3.4 of the datasheet.
What debug interfaces does R5F111NFGLA#W0 support?
R5F111NFGLA#W0 supports Renesas' on-chip debug interface via TOOL0, TOOLRxD, and TOOLTxD pins - enabling full SWD-style debugging, flash programming, and real-time trace using E2 studio and Renesas E2 emulator. No JTAG port is present; debug is exclusively through the dedicated TOOL interface.
