Product details
Overview
R5F110NJGLA#W0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (up to 56 segments × 8 commons), 256 KB flash, 16 KB RAM, USB 2.0 function controller (full-speed/low-speed), and 12-bit A/D converter-designed for battery-powered LCD-based medical devices, industrial HMIs, and smart meters operating from 1.6 V to 3.6 V.
For engineers reviewing the R5F110NJGLA#W0 datasheet, R5F110NJGLA#W0 pinout, R5F110NJGLA#W0 application, or R5F110NJGLA#W0 equivalent, key selection criteria include its 85-pin VFLGA package, -40°C to +105°C industrial temperature grade, USB 2.0 compliance with Battery Charging Spec 1.2, and true low-power operation down to 0.68 μA in RTC2+LVD mode.
Technical Context

It integrates a dedicated USB voltage regulator (UREGC/UVBUS), on-chip high-accuracy oscillator (±1.0% over -20°C to +85°C), and dual-clock domain (main + subsystem) supporting HALT/STOP/SNOOZE low-power modes.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, 5-channel I²C-compatible interfaces, 4-channel UART/LIN, 4-channel CSI, 2-channel comparators, and event link controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F110NJALA#U0 | Same die, consumer-grade (-40°C to +85°C), same 85-pin VFLGA but tray packaging (#U0) | Not qualified for industrial ambient or extended thermal cycling; unsuitable for DIN-rail or outdoor metering | Select only for cost-sensitive consumer HMI where temperature range is limited to indoor use. |
| R5F110PJGLA#W0 | Same package and temp grade, but 100-pin LFQFP, 256 KB flash, 56-segment LCD, and 2× comparators (vs. 1× in R5F110NJGLA#W0) | Required when >44 LCD segments or dual comparator functions (e.g., windowed battery monitoring) are needed | Choose when design requires additional I/O, larger segment count, or redundant analog monitoring paths. |
Compared with R5F110NJALA#U0, the R5F110NJGLA#W0 provides guaranteed operation up to +105°C and embossed tape for automated assembly; versus R5F110PJGLA#W0, it offers identical flash/RAM but reduced pin count and LCD capacity-lowering PCB layer count and assembly cost where 44 segments suffice.

FAQ
What is the maximum LCD segment count supported by the R5F110NJGLA#W0?
The R5F110NJGLA#W0 supports up to 56 segment outputs and 8 common outputs, configurable for static, 1/2, 1/3, or 1/4 bias drive. Its actual usable segment count depends on common count selection: 44 segments with 4 commons or 56 segments with 8 commons. This matches the R5F110NJGLA#W0's pin-mapped SEG0–SEG55 and COM0–COM7 resources as defined in the RL78/L1C datasheet Rev.2.40.
Does the R5F110NJGLA#W0 include USB device functionality out of the box?
Yes, the R5F110NJGLA#W0 integrates a full USB 2.0 function controller supporting both full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, with native compliance to USB Battery Charging Specification Revision 1.2. No external PHY or level-shifter is required-the R5F110NJGLA#W0 drives UDP/UDM directly with on-die termination and UREGC-regulated voltage.
What are the power supply requirements for the R5F110NJGLA#W0's USB interface?
The R5F110NJGLA#W0 requires a 0.33 μF capacitor between UREGC and VSS to stabilize the internal USB voltage regulator. UVBUS must be connected to the host VBUS line (4.4–5.25 V) for detection; the R5F110NJGLA#W0 itself operates from 1.6–3.6 V on VDD0/VDD1 and does not draw power from UVBUS for core logic.
Can the R5F110NJGLA#W0 operate in STOP mode while maintaining RTC2 and LVD functionality?
Yes, the R5F110NJGLA#W0 achieves 0.68 μA typical current consumption in STOP mode with RTC2 and LVD active-enabling calendar-based wake-up and brown-out protection without waking the CPU. This is confirmed in Section 1.1 "Features" of the R5F110NJGLA#W0 datasheet (R01DS0192EJ0240 Rev.2.40), specifying "0.68 μA for RTC2 + LVD".
How many analog input channels does the R5F110NJGLA#W0 support at 12-bit resolution?
The R5F110NJGLA#W0 supports 13 analog input channels for 12-bit A/D conversion, but only when VDD is ≥ 2.4 V. Channels include ANI0–ANI6, ANI16–ANI21, and AVREFP/AVREFM. At lower VDD (1.6–2.3 V), the A/D operates at 8/10-bit resolution. This behavior is explicitly stated in the "A/D converter" subsection of the R5F110NJGLA#W0 datasheet.
