Product details
Overview
R5F110NEGLA#W0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (44–56 segment, 4–8 common), USB 2.0 function controller (full-speed/low-speed), 12-bit A/D converter (VDD = 2.4–3.6 V), and 96 KB flash memory. It operates from 1.6 V to 3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD-based human interface devices.
For engineers reviewing the R5F110NEGLA#W0 datasheet, R5F110NEGLA#W0 pinout, R5F110NEGLA#W0 application, or R5F110NEGLA#W0 equivalent, key selection criteria include its VFLGA-85 package, industrial temperature range (−40°C to +105°C), USB functionality, LCD drive capability, and true low-power modes (0.68 μA RTC2 + LVD).
Technical Context
The R5F110NEGLA#W0 integrates the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.04167 μs (@24 MHz) to 30.5 μs (@32.768 kHz). It features a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip high-speed oscillator (±1.0% accuracy), and dual-clock domain operation (main + subsystem clocks).
Its peripheral set includes a 16-channel timer array (11 channels usable), event link controller (ELC) for hardware-triggered peripheral chaining, data transfer controller (DTC), and LCD controller supporting internal boosting, capacitor split, or external resistor division methods-all configurable via register settings without external components.

FAQ
What is the operating temperature range for the R5F110NEGLA#W0?
The R5F110NEGLA#W0 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number. This makes it suitable for deployment in harsh environments such as factory automation panels, outdoor meters, and under-hood automotive accessories where extended thermal stability is required. The device maintains full specification compliance across this entire range.
Does the R5F110NEGLA#W0 support USB device enumeration without external components?
Yes, the R5F110NEGLA#W0 includes a fully integrated USB 2.0 function controller with internal transceivers and voltage regulator. When used with the required UREGC (0.33 μF) and proper PCB layout (including 27 Ω series resistors on UDP/UDM), it achieves full-speed enumeration without external PHY or level-shifting components - reducing BOM count and board area.
How many LCD segments and commons does the R5F110NEGLA#W0 support?
The R5F110NEGLA#W0 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling configurations such as 44 segments × 4 commons or 52 segments × 8 commons depending on drive method. The exact count is determined by register configuration and external capacitor/resistor network selection - no external driver IC is needed for standard segment LCDs.
What low-power modes are available on the R5F110NEGLA#W0, and what is the lowest current draw?
The R5F110NEGLA#W0 offers HALT, STOP, and SNOOZE modes. In STOP mode with RTC2 and LVD enabled, it draws just 0.68 μA - verified at VDD = 3.0 V and TA = 25°C. This allows decade-long battery life in applications like utility meters and portable instruments where periodic wake-up and timekeeping are essential.
Is the R5F110NEGLA#W0 pin-compatible with other RL78/L1C variants in the VFLGA-85 package?
Yes, all RL78/L1C devices in the VFLGA-85 package - including R5F110NEGLA#W0, R5F110NFGLA#W0, and R5F111NEGLA#W0 - share identical pinouts and footprint. Functional differences (e.g., USB presence, flash size) are implemented internally; no PCB redesign is needed when migrating between these variants during design-in or production ramp.
