Renesas R5F110NGGLA#U0

Overview

R5F110NGGLA#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, 2.4–3.6 V range), USB 2.0 function controller (full/low-speed), and 128 KB flash memory. It operates from 1.6–3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD-based medical, industrial, and consumer instrumentation.

For engineers reviewing the R5F110NGGLA#U0 datasheet, R5F110NGGLA#U0 pinout, R5F110NGGLA#U0 application, or R5F110NGGLA#U0 equivalent, key selection criteria include its VFLGA-85 package, industrial-grade temperature range (−40 to +105°C), USB functionality, LCD drive capability, and true low-power operation down to 0.68 μA in RTC2+LVD mode.

Technical Context

The R5F110NGGLA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip PLL for high-speed clock generation, and dual-clock domain support (main system clock + subsystem clock).

Its peripheral set includes a 30-source interrupt-capable Data Transfer Controller (DTC), Event Link Controller (ELC) for hardware-triggered peripheral chaining, and LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods - all configurable via register settings without external components.

FAQ

What is the operating temperature range for the R5F110NGGLA#U0?

The R5F110NGGLA#U0 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 medical equipment, and under-hood automotive cabin controls where extended thermal stability is required. The R5F110NGGLA#U0 maintains full functionality across this range without derating.

Does the R5F110NGGLA#U0 support USB device enumeration without external components?

Yes, the R5F110NGGLA#U0 integrates a USB 2.0 function controller with an internal 3.3 V regulator, enabling full-speed and low-speed enumeration using only the UREGC, UVBUS, UDM, and UDP pins. No external PHY or level-shifting components are needed. The R5F110NGGLA#U0 complies with USB Battery Charging Specification Rev. 1.2 and supports standard USB descriptors for CDC, HID, and MSC classes out of the box.

How many LCD segments and commons does the R5F110NGGLA#U0 support?

The R5F110NGGLA#U0 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling drive configurations up to 1/8 duty cycle with 448 total segments. Segment mapping is flexible via register configuration, and the LCD controller supports internal voltage boosting, capacitor-split, and external resistor-division bias methods - all selectable in software. The R5F110NGGLA#U0 requires no external LCD driver IC.

What is the maximum A/D conversion resolution and input count supported by the R5F110NGGLA#U0?

The R5F110NGGLA#U0 provides a 12-bit successive-approximation A/D converter with 12 analog input channels (ANI0–ANI6, ANI16–ANI21), internal reference voltage (TYP. 1.45 V), and integrated temperature sensor. Resolution is guaranteed at 12 bits when VDD is 2.4–3.6 V; at lower VDD (1.6–2.4 V), it operates at 8/10-bit mode. The R5F110NGGLA#U0 supports simultaneous sampling control via the DTC and ELC for synchronized multi-channel acquisition.

Can the R5F110NGGLA#U0 execute code while rewriting data flash memory?

Yes, the R5F110NGGLA#U0 supports Background Operation (BGO) for data flash memory, allowing program code execution from main flash while data flash is being rewritten. This enables seamless runtime parameter updates, calibration storage, or event logging without halting application logic. The R5F110NGGLA#U0 guarantees 1,000,000 write cycles and supports voltage-programming from 1.8–3.6 V, making it ideal for field-updatable embedded systems.
