Product details
Overview
R5F110NGALA#U0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (44–56 segment, 4–8 common), 12-bit A/D converter (12-channel, VDD = 2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), and 96 KB flash memory. It operates from 1.6 V to 3.6 V and targets battery-powered LCD-based human interface devices such as smart meters and portable medical displays.
For engineers reviewing the R5F110NGALA#U0 datasheet, R5F110NGALA#U0 pinout, R5F110NGALA#U0 application, or R5F110NGALA#U0 equivalent, key selection criteria include its VFLGA-85 package, USB functionality, RTC2 + LVD standby current of 0.68 μA, and support for 33 DMIPS at 24 MHz - critical for energy-constrained embedded UI designs.
Technical Context
The R5F110NGALA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs min @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip PLL, and dual-clock system supporting high-speed main and low-speed subsystem domains.
Its peripheral set includes 11 × 16-bit timers, event link controller (ELC) for hardware-triggered peripheral chaining, data transfer controller (DTC) with chain transfer, and LCD driver supporting internal boosting, capacitor split, and external resistor division methods - enabling flexible segment/common drive configurations without external bias circuitry.

FAQ
What is the maximum LCD segment count supported by the R5F110NGALA#U0?
The R5F110NGALA#U0 supports up to 56 segment outputs and 8 common outputs, configurable via software-selectable drive methods (internal voltage boosting, capacitor split, or external resistance division). This enables direct driving of large alphanumeric or custom icon displays without external bias ICs - verified in Section 1.1 "Features" and Figure 1-1 of the R01DS0192EJ0240 datasheet.
Does the R5F110NGALA#U0 support USB device enumeration without external components?
Yes, the R5F110NGALA#U0 integrates a full USB 2.0 function controller with internal transceiver and voltage regulator. When UREGC is decoupled with a 0.33 μF capacitor and UVBUS is properly biased, the R5F110NGALA#U0 achieves full-speed (12 Mbps) enumeration as a CDC or HID device - confirmed in Section 1.1 "USB" and Pin Configuration 1.3.3 of R01DS0192EJ0240.
What is the guaranteed operating temperature range for the R5F110NGALA#U0?
The R5F110NGALA#U0 is rated for −40°C to +85°C ambient operation (Consumer grade, "A" suffix), as specified in Section 1.1 "Operating ambient temperature" and Ordering Information Table 1.2 of R01DS0192EJ0240. It is not qualified for industrial −40°C to +105°C operation - that requires "G"-suffixed variants like R5F110NGGLA#U0.
How many analog input channels does the 12-bit A/D converter in the R5F110NGALA#U0 support?
The R5F110NGALA#U0's 12-bit A/D converter supports 12 analog input channels (ANI0–ANI6, ANI16–ANI21), with internal reference voltage (1.45 V TYP) and integrated temperature sensor. Operation requires VDD ≥ 2.4 V - stated in Section 1.1 "A/D converter" and validated in Memory Map Table on Page 2 of R01DS0192EJ0240.
Is the R5F110NGALA#U0 pin-compatible with other RL78/L1C family members in the same package?
Yes, all 85-pin VFLGA RL78/L1C variants - including R5F110MEALA#U0 through R5F110PJALA#U0 and R5F111xxALA#U0 - share identical pinouts and package dimensions (PVLG0085JA-A). Functional differences (e.g., USB presence, flash size) do not affect physical compatibility - confirmed in Tables 1.2 and 1.3.3 of R01DS0192EJ0240.
