Product details
Overview
R5F110MFGFB#30 from Renesas is an RL78/L1C 80-pin ultra-low-power 16-bit MCU with integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (12 ch, VDD = 2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), and 128 KB flash memory - designed for battery-powered LCD-based metering and industrial HMI applications.
For engineers reviewing the R5F110MFGFB#30 datasheet, R5F110MFGFB#30 pinout, R5F110MFGFB#30 application, or R5F110MFGFB#30 equivalent, key selection criteria include verified USB 2.0 functionality, 128 KB code flash with 8 KB data flash, 16 KB RAM, -40 to +105°C industrial temperature grade, and LFQFP-80 package compatibility with existing RL78/L1C layout footprints.
Technical Context
The R5F110MFGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @ 24 MHz PLL clock). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip high-speed oscillator (±1.0% accuracy), and dual-clock domain operation supporting HS main mode (for USB) and subsystem clock (32.768 kHz RTC).
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, event link controller (ELC) for hardware-triggered peripheral chaining, and LCD driver supporting internal boosting, capacitor split, or external resistor division methods - all optimized for low-power segment-driven displays in energy-conscious designs.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F110MFGFB#30?
The R5F110MFGFB#30 operates up to 24 MHz using its on-chip PLL or high-speed oscillator. At this frequency, it achieves 33 DMIPS performance with active current as low as 112.5 μA/MHz - meaning ~2.7 mA typical at 24 MHz. In STOP mode with RTC2 + LVD enabled, current drops to 0.68 μA, making R5F110MFGFB#30 ideal for intermittent-sensing applications.
Does the R5F110MFGFB#30 support USB device enumeration without external PHY components?
Yes, the R5F110MFGFB#30 integrates a full USB 2.0 function controller with internal transceivers, requiring only passive termination (1.5 kΩ pull-up on UDP for full-speed detection) and proper UREGC/UVBUS decoupling. No external PHY or level-shifter is needed - R5F110MFGFB#30 handles USB signaling, protocol stack, and descriptor management in firmware.
How many LCD segments and commons does the R5F110MFGFB#30 support, and what bias methods are available?
The R5F110MFGFB#30 supports up to 44 segment outputs and 4 common outputs (or 52 segments × 8 commons in alternate configuration). It provides three LCD bias generation methods: internal voltage boosting, capacitor split, and external resistance division - selected via register settings to match display glass requirements without external components.
What are the key differences between R5F110MFGFB#30 and R5F111MFGFB#30?
R5F110MFGFB#30 includes a USB 2.0 function controller and associated pins (UREGC, UVBUS, UDM, UDP); R5F111MFGFB#30 omits USB entirely. All other specifications - 128 KB flash, 12 KB RAM, LCD driver, ADC, timers, and package - are identical. R5F110MFGFB#30 is selected when USB connectivity is required; R5F111MFGFB#30 reduces cost and EMI in non-USB applications.
Is the R5F110MFGFB#30 compatible with Renesas' standard debugging and programming tools?
Yes, the R5F110MFGFB#30 supports Renesas E2 emulator Lite and E2 studio IDE via its on-chip debug interface. Programming is performed through the TOOL0 pin (SWD-compatible) or via UART bootloader. Flash security features (block erase prohibition, flash shield window) are fully supported in R5F110MFGFB#30 to protect firmware IP during development and production.
