Product details
Overview
R5F111NJGLA#U0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller designed for ultra-low-power LCD-based applications. It integrates a 12-bit A/D converter (2.4–3.6 V), USB 2.0 function controller (full/low-speed), LCD controller/driver supporting up to 56 segments and 8 commons, and delivers 33 DMIPS at 24 MHz with operation down to 1.6 V. It targets battery-powered medical devices, portable instrumentation, and industrial HMI panels.
For engineers reviewing the R5F111NJGLA#U0 datasheet, R5F111NJGLA#U0 pinout, R5F111NJGLA#U0 application, or R5F111NJGLA#U0 equivalent, key selection criteria include its 192 KB flash / 8 KB data flash / 16 KB RAM memory configuration, industrial-grade −40 to +105°C temperature range (G-grade), VFLGA-85 package with 0.65 mm pitch, and integrated LCD bias generation without external charge pumps.
Technical Context
The R5F111NJGLA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.04167 μs (24 MHz) to 30.5 μs (32.768 kHz). Its peripheral set includes 11 × 16-bit timers, real-time clock 2 with calendar and alarm, 5-channel I²C, 4-channel UART/LIN, and 4-channel CSI-each configurable via peripheral I/O redirection registers (PIOR).
Power management features include HALT, STOP, and SNOOZE modes, achieving as low as 112.5 μA/MHz active current and 0.68 μA in RTC2+LVD standby. The device uses dual voltage domains: AVDD/AVSS for analog peripherals and VDD0/VSS0 for digital logic, with dedicated REGC and UREGC pins for internal regulator decoupling.

|---|---|---|---|
| R5F111NJAFB#30 | Same core, memory, and peripherals but in 80-pin LFQFP (12×12 mm, 0.5 mm pitch); lacks USB functionality | Suitable for cost-sensitive, non-USB LCD applications where board space allows larger package | Select when USB is unnecessary and legacy LFQFP layout compatibility is required |
| R5F111PJGLA#U0 | Same 85-pin VFLGA package and USB support, but with 256 KB flash, 16 KB RAM, and extended 100-pin variant feature set | Targeted at more complex HMI with larger firmware, additional peripherals, or future scalability needs | Choose when firmware growth or enhanced peripheral concurrency (e.g., extra UART/I²C) is anticipated |
Compared with R5F111NJAFB#30, the R5F111NJGLA#U0 adds USB 2.0 and uses a smaller VFLGA package, reducing PCB area by ~30%; versus R5F111PJGLA#U0, it trades 64 KB flash and 0.5 KB RAM for lower unit cost and identical peripheral count in compact form factor.

FAQ
What is the operating temperature range for the R5F111NJGLA#U0?
The R5F111NJGLA#U0 is rated for industrial operation from −40 to +105°C (G-grade), validated across its full voltage range (1.6–3.6 V) and all specified peripherals including USB and LCD driver. This makes R5F111NJGLA#U0 suitable for deployment in harsh environments such as factory automation panels and outdoor metering equipment.
Does the R5F111NJGLA#U0 support USB device enumeration without external components?
Yes - the R5F111NJGLA#U0 includes a fully integrated USB 2.0 function controller with internal transceivers and voltage regulator. Only UREGC (0.33 μF to VSS), UVBUS pull-up, and standard 27 Ω series resistors on UDP/UDM are required. No external PHY or crystal is needed, as the USB clock derives from the internal PLL.
How many LCD segments and commons does the R5F111NJGLA#U0 support?
The R5F111NJGLA#U0 supports up to 56 segment outputs and 8 common outputs (SEG0–SEG55, COM0–COM7), enabling static, 1/2, 1/3, or 1/4 duty drive configurations. With 8 commons active, up to 52 segments are available - confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver".
Can the R5F111NJGLA#U0 perform A/D conversion while in low-power STOP mode?
No - the 12-bit A/D converter requires the high-speed on-chip oscillator or PLL clock, which is disabled in STOP mode. However, the R5F111NJGLA#U0 supports A/D conversion in HALT mode (CPU stopped, peripherals active) and SNOOZE mode (selective peripheral wake-up), both enabling precise measurement with sub-μA background current.
What debug interface does the R5F111NJGLA#U0 provide?
The R5F111NJGLA#U0 includes a full on-chip debug system accessible via the TOOL0 pin (SWD-compatible serial wire debug) and supports breakpoints, watchpoints, and flash programming. No external JTAG adapter is required - standard Renesas E2 or E2 Lite debuggers connect directly using the 5-pin SWD header defined in the RL78/L1C User's Manual.
