Overview
R5F110NJALA#U0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (up to 56 segments × 8 commons), USB 2.0 function controller (full-speed/low-speed), 12-bit A/D converter (VDD = 2.4–3.6 V), 256 KB flash, and 16 KB RAM - designed for battery-powered LCD-based medical devices, smart meters, and portable instrumentation.
For engineers reviewing the R5F110NJALA#U0 datasheet, R5F110NJALA#U0 pinout, R5F110NJALA#U0 application, or R5F110NJALA#U0 equivalent, key selection criteria include its 85-pin VFLGA package, USB 2.0 functional capability, RTC2 with calendar/alarm, true low-power operation (0.68 μA in RTC2+LVD mode), and integrated LCD voltage boosting.
Technical Context
The R5F110NJALA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip PLL for USB clock generation, and dual-clock domain support (main system clock + subsystem clock).
Its LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods; segment output is configurable up to 56 segments with 8 commons. The USB interface complies with Battery Charging Specification Rev. 1.2 and operates in HS (high-speed main) mode only.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F110NJGFB#30 | 80-pin LFQFP (12×12 mm), same flash/RAM/USB/LCD specs, but different package and thermal profile | Preferred for PCBs requiring larger pitch (0.5 mm) and higher thermal dissipation; not pin-compatible with VFLGA | Select when mechanical constraints favor QFP over VFLGA or when reflow compatibility with legacy LFQFP processes is required |
| R5F111NJALA#U0 | Identical 85-pin VFLGA package and pinout, but lacks USB 2.0 controller and uses lower-power USB-less peripheral set | Suitable for cost-sensitive LCD applications where USB connectivity is unnecessary; shares same footprint and debug interface | Choose when USB functionality is omitted to reduce BOM cost and simplify certification - retains all other peripherals and low-power features |
Compared with R5F110NJALA#U0, R5F110NJGFB#30 offers easier hand-soldering and better heat dissipation but requires PCB redesign, while R5F111NJALA#U0 provides identical form factor and software compatibility at lower unit cost when USB is unused.

FAQ
What USB speed modes does the R5F110NJALA#U0 support?
The R5F110NJALA#U0 supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB 2.0 operation. Its USB function controller complies with Battery Charging Specification Revision 1.2, enabling DCP detection. Operation requires HS (high-speed main) mode activation and proper UREGC/UVBUS decoupling per the datasheet.
How many LCD segments and commons does the R5F110NJALA#U0 drive?
The R5F110NJALA#U0 drives up to 56 segments and 8 commons (or 44 segments and 4 commons) using its integrated LCD controller/driver. Segment outputs (SEG0–SEG55) and common outputs (COM0–COM7) are configurable via register settings, and internal voltage boosting eliminates need for external bias circuitry.
What is the minimum operating voltage for the R5F110NJALA#U0's 12-bit A/D converter?
The 12-bit A/D converter in the R5F110NJALA#U0 requires VDD ≥ 2.4 V for full 12-bit resolution operation. At lower VDD (1.6–2.3 V), it operates in 8/10-bit mode. This voltage dependency ensures accuracy across battery discharge curves while maintaining compatibility with 1.6 V minimum system supply.
Does the R5F110NJALA#U0 support background data flash rewriting?
Yes, the R5F110NJALA#U0 supports background operation (BGO) for its 8 KB data flash memory. Instructions can be executed from program memory while data flash is being rewritten, enabling concurrent firmware execution and non-volatile parameter updates without system interruption - critical for fail-safe logging in medical devices.
What is the RTC2 calendar range and alarm capability of the R5F110NJALA#U0?
The R5F110NJALA#U0's RTC2 module supports a 99-year calendar (year/month/day/hour/minute/second), includes programmable alarm interrupt (single or periodic), and features hardware clock correction. It remains operational in STOP mode with only 0.68 μA current draw when paired with LVD, making it ideal for time-stamped data logging in battery-powered systems.
