Product details
Overview
R5F111NHGLA#U0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller designed for ultra-low-power LCD-based applications, featuring 128 KB flash, 12 KB RAM, 12-bit A/D converter (2.4–3.6 V), integrated LCD controller/driver (up to 56 segments × 8 commons), and USB 2.0 function controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes.
For engineers reviewing the R5F111NHGLA#U0 datasheet, R5F111NHGLA#U0 pinout, R5F111NHGLA#U0 application, or R5F111NHGLA#U0 equivalent, key selection considerations include its industrial-grade temperature range (−40 to +105°C), true low-power operation (0.68 μA in RTC2+LVD mode), on-chip debug support, and USB Battery Charging Specification Rev. 1.2 compliance.
Technical Context
The R5F111NHGLA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz or 30.5 μs at 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), supports USB function-only operation (no host mode), and includes hardware event linking (ELC) for deterministic peripheral triggering without CPU intervention.
Its LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods; segment output capability is 52 signals (with 8 commons), common output is 8 channels. The device includes two comparators, dual D/A converters (8-bit, 0–VDD output), and a real-time clock 2 (RTC2) with calendar, alarm, and clock correction functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111NJGLA#U0 | 256 KB flash, 16 KB RAM, same package and peripherals - no change in USB/LCD timing or pinout | Required for larger firmware images or extended data logging buffers | Select when >128 KB flash is needed; identical footprint and qualification for industrial use |
| R5F110NHGLA#U0 | Includes USB PHY and full-speed transceiver; otherwise identical flash/RAM/peripherals - shares same VFLGA-85 package | Supports USB host capability and higher-speed peripheral attachment (e.g., USB HID keyboard/mouse) | Choose only if USB host functionality is required; R5F111NHGLA#U0 is function-only and lower-cost |
Compared with R5F111NJGLA#U0, this part trades flash capacity for cost and density; compared with R5F110NHGLA#U0, it removes USB host capability to reduce silicon area and power, making it optimal for pure USB-peripheral LCD applications requiring long battery life and industrial temperature resilience.

FAQ
What is the maximum LCD segment count supported by R5F111NHGLA#U0?
R5F111NHGLA#U0 supports up to 52 segment outputs and 8 common outputs, enabling 416-segment LCD driving in 8-multiplex mode. This is confirmed in Section 1.1 (Features) and Figure 1-1 of the R01DS0192EJ0240 datasheet. The actual usable segments depend on selected bias method and COM count configuration.
Does R5F111NHGLA#U0 support USB host functionality?
No, R5F111NHGLA#U0 implements only USB 2.0 function controller logic - it cannot act as a USB host. Host capability requires the R5F110x series (e.g., R5F110NHGLA#U0), which includes additional PHY and protocol layers. R5F111NHGLA#U0 is strictly a USB peripheral device.
What is the operating temperature range for R5F111NHGLA#U0?
R5F111NHGLA#U0 is rated for industrial applications with an operating ambient temperature range of −40 to +105°C, as specified in Section 1.1 under "Operating ambient temperature (G: Industrial applications)" and confirmed in the ordering information table on page 3 of R01DS0192EJ0240.
Can R5F111NHGLA#U0 perform background data flash rewriting?
Yes, R5F111NHGLA#U0 supports Background Operation (BGO) for data flash: instructions can execute from program memory while data flash is being rewritten. This is documented in Section 1.1 under "Data flash memory" and enables seamless firmware updates and data logging without halting real-time tasks.
Is the 12-bit A/D converter in R5F111NHGLA#U0 usable across the full 1.6–3.6 V supply range?
No - the 12-bit A/D converter requires VDD ≥ 2.4 V, as explicitly stated in Section 1.1: "12-bit resolution A/D converter (VDD = 2.4 to 3.6 V)". At 1.6–2.3 V, only 8/10-bit mode is available. This constraint must be considered in low-voltage battery designs.
