Product details
Overview
R5F110NFALA#W0 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 64 KB flash memory. It operates from 1.6 V to 3.6 V and delivers 33 DMIPS at 24 MHz, targeting battery-powered LCD-based medical devices, home appliances, and industrial control panels.
For engineers reviewing the R5F110NFALA#W0 datasheet, R5F110NFALA#W0 pinout, R5F110NFALA#W0 application, or R5F110NFALA#W0 equivalent, key selection criteria include its VFLGA-85 package, USB 2.0 functionality, RTC2 + LVD ultra-low-power operation (0.68 μA), and integrated LCD driving capability without external bias circuitry.
Technical Context
The R5F110NFALA#W0 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, and dual-clock system supporting high-speed main and low-speed subsystem clocks.
Its LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods, with programmable segment/common drive configurations. The USB 2.0 function controller complies with Battery Charging Specification Rev. 1.2 and supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) modes exclusively in HS (high-speed main) mode.

FAQ
What is the maximum LCD segment count supported by the R5F110NFALA#W0?
The R5F110NFALA#W0 supports up to 56 segment outputs and 8 common outputs, configurable for static or multiplexed (1/4 to 1/8 duty) LCDs. When using 4 commons, up to 44 segments are available; with 8 commons, all 56 segments can be driven. This matches standard 4×14 or 8×7 segment layouts found in medical and appliance displays.
Does the R5F110NFALA#W0 support USB device enumeration without external components?
Yes, the R5F110NFALA#W0 includes an integrated USB 2.0 function controller with internal 3.3 V regulator. Only two external 0.33 μF (UREGC) and 0.47–1 μF (REGC) decoupling capacitors are required - no external USB PHY, level shifters, or pull-up resistors are needed for basic full-speed enumeration.
What are the power supply requirements for the R5F110NFALA#W0's analog and LCD sections?
The R5F110NFALA#W0 requires separate analog (AVDD/AVSS) and digital (VDD0/VSS0) supplies, both operating from 1.6 V to 3.6 V. The LCD section uses VL1–VL4 pins powered from internal charge pump or external sources; CAPH/CAPL pins must be connected to external capacitors (typically 1 μF) for internal boosting operation.
Can the R5F110NFALA#W0 perform ADC conversions while in low-power STOP mode?
No - the 12-bit A/D converter requires the high-speed on-chip oscillator or PLL to be active and cannot operate in STOP mode. However, the device supports SNOOZE mode, where the ADC can trigger autonomously from a low-power timer and wake the CPU only upon conversion completion, achieving ~2.5 μA average current in periodic sensing.
Is the R5F110NFALA#W0 pin-compatible with other RL78/L1C variants in the VFLGA-85 package?
Yes, all RL78/L1C devices in the 85-pin VFLGA package - including R5F110MEALA#W0 through R5F110NJALA#W0 and R5F111xxALA#W0 series - share identical pinouts and electrical characteristics. This allows hardware reuse across different flash sizes and USB-enabled variants without PCB redesign.
