Product details
Overview
R5F111NJGLA#V0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller designed for ultra-low-power LCD-based applications. It features 192 KB flash, 16 KB RAM, 12-bit A/D converter (2.4–3.6 V), integrated LCD controller/driver (up to 56 segments × 8 commons), and operates from 1.6 V to 3.6 V across –40°C to +105°C industrial temperature range.
For engineers reviewing the R5F111NJGLA#V0 datasheet, R5F111NJGLA#V0 pinout, R5F111NJGLA#V0 application, or R5F111NJGLA#V0 equivalent, key selection criteria include LCD segment drive capability, RTC2 calendar support, USB absence (vs. 110-series), low-power STOP/HALT modes, and industrial-grade thermal reliability.
Technical Context
The R5F111NJGLA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It supports multiply/divide and multiply-accumulate instructions within a 1 Mbyte address space.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with 99-year calendar and alarm, 5-channel I²C/Simplified I²C, 4-channel UART/LIN, 4-channel CSI/SPI, 2-channel comparator, and background operation-capable 8 KB data flash (1M rewrite cycles).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111NJAFB#30 | Same core, flash, RAM, and peripherals; differs in package (80-pin LFQFP vs. 85-pin VFLGA) and temp grade (A: –40°C to +85°C) | Suitable for consumer-grade, PCB-space-constrained designs where VFLGA footprint is not feasible | Select when board layout requires larger pitch (0.5 mm) or lower temperature rating is acceptable |
| R5F111PHGLA#V0 | Same package and temp grade; reduced memory (128 KB flash, 12 KB RAM); fewer I/O (77 vs. 77 - identical count but different pin mapping) | Cost-optimized variant for simpler LCD interfaces requiring ≤128 KB code and no dual DAC | Choose when application fits within smaller memory footprint and does not require second D/A channel or extra timers |
Compared with R5F111NJGLA#V0, R5F111NJAFB#30 trades VFLGA miniaturization for easier hand-soldering and wider thermal margin tolerance, while R5F111PHGLA#V0 reduces cost by trimming flash/RAM without altering peripheral count or LCD capability - enabling scalable family-based design reuse.

FAQ
Does R5F111NJGLA#V0 support USB functionality?
No, R5F111NJGLA#V0 does not include a USB controller. It belongs to the "111" series, which explicitly omits USB hardware - unlike the "110" series (e.g., R5F110NJGLA#V0). Pins UREGC, UVBUS, UDM, and UDP are no-connect on R5F111NJGLA#V0 and must be left unconnected in layout.
What LCD configurations does R5F111NJGLA#V0 support?
R5F111NJGLA#V0 supports up to 56 segment outputs and 8 common outputs. Segment count varies with common count: 56 segments × 4 commons or 44 segments × 8 commons. Voltage generation methods - internal boosting, capacitor split, or external resistor division - are software-selectable per application requirements.
What is the maximum operating frequency and associated power consumption of R5F111NJGLA#V0?
R5F111NJGLA#V0 operates up to 24 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this speed, typical active current is 112.5 μA/MHz. In STOP mode with RTC2 and LVD active, it draws just 0.68 μA - verified across the full –40°C to +105°C industrial temperature range.
How many analog inputs and what ADC resolution does R5F111NJGLA#V0 provide?
R5F111NJGLA#V0 provides 13 analog input channels (ANI0–ANI6, ANI16–ANI21). Its A/D converter delivers 12-bit resolution when VDD is 2.4–3.6 V, and 8/10-bit resolution at 1.6–3.6 V. An internal reference voltage (TYP. 1.45 V) and integrated temperature sensor are also available.
Is R5F111NJGLA#V0 pin-compatible with other RL78/L1C variants?
R5F111NJGLA#V0 is pin-compatible within the 85-pin VFLGA "111" series (e.g., R5F111MHGLA#V0, R5F111PHGLA#V0) but not with "110" (USB-enabled) or "111" LFQFP variants. Pin functions match across same-package 111-series parts; differences lie only in memory size and peripheral enablement - confirmed in Renesas datasheet Section 1.3.4.
