Product details
Overview
R5F111MGGFB#30 from Renesas is an 80-pin RL78/L1C 16-bit microcontroller without USB, featuring 128 KB flash, 12 KB RAM, integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (12-channel, VDD ≥ 2.4 V), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD-based industrial instrumentation.
For engineers reviewing the R5F111MGGFB#30 datasheet, R5F111MGGFB#30 pinout, R5F111MGGFB#30 application, or R5F111MGGFB#30 equivalent, key selection criteria include industrial-grade temperature range (−40°C to +105°C), LFQFP-80 package compatibility, LCD drive capability with internal voltage boosting, and absence of USB peripheral - critical for cost-sensitive, low-power HMI designs requiring long-term supply stability.
Technical Context
The R5F111MGGFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.04167 μs (24 MHz) to 30.5 μs (32.768 kHz), and includes multiply/divide/accumulate instructions. It integrates a 12-bit interval timer, real-time clock 2 (RTC2) with calendar and alarm, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes four UART/LIN channels, five I²C/simplified I²C channels, four CSI (SPI-compatible) channels, eleven 16-bit timers, two 8-bit D/A converters, two comparators, and a data transfer controller (DTC) with chain transfer support - all coordinated via the event link controller (ELC) for deterministic low-latency peripheral triggering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MHGFB#30 | 192 KB flash, 16 KB RAM, same 80-pin LFQFP package and peripheral set | Supports larger firmware (e.g., OTA update stack + dual-bank bootloader) without layout change | Select when future firmware expansion headroom or enhanced data logging capacity is required |
| R5F110MGGFB#30 | Includes USB 2.0 function controller (full/low-speed), otherwise identical flash/RAM/peripherals | Enables PC connectivity for configuration, diagnostics, or firmware updates via USB HID/CDC | Choose only if USB host/device interface is mandatory; adds UREGC/UVBUS/UDP/UDM routing complexity |
Compared with R5F111MHGFB#30, the R5F111MGGFB#30 trades flash capacity for lower unit cost and smaller die size, while retaining identical low-power behavior and LCD drive capability; versus R5F110MGGFB#30, it removes USB hardware to simplify layout, reduce BOM, and eliminate USB regulator design constraints - ideal for sealed, battery-operated devices.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F111MGGFB#30?
The R5F111MGGFB#30 operates up to 24 MHz using its high-speed on-chip oscillator or PLL, delivering 33 DMIPS. Its minimum instruction execution time is 0.04167 μs at 24 MHz, and it supports dynamic clock scaling down to 32.768 kHz (30.5 μs/instruction) for ultra-low-power RTC operation - enabling adaptive performance/power trade-offs in battery-constrained designs.
Does the R5F111MGGFB#30 support USB functionality?
No, the R5F111MGGFB#30 does not include USB hardware. It belongs to the "111" series (no USB), unlike the "110" series (e.g., R5F110MGGFB#30) which integrates a USB 2.0 function controller. This omission simplifies power design (no UREGC/UVBUS routing) and reduces cost, making R5F111MGGFB#30 optimal for standalone LCD applications without PC connectivity requirements.
How many LCD segments and commons does the R5F111MGGFB#30 support in its 80-pin configuration?
In the 80-pin LFQFP package, the R5F111MGGFB#30 supports up to 44 segment outputs (e.g., SEG0–SEG6, SEG12–SEG25, SEG27–SEG42, SEG48–SEG55) and 4 common outputs (COM0–COM3). The datasheet confirms this configuration for 80-pin "without USB" variants, enabling alphanumeric or custom symbol displays without external segment drivers.
What are the key low-power modes available on the R5F111MGGFB#30 and their typical current draw?
The R5F111MGGFB#30 offers HALT, STOP, and SNOOZE modes. STOP mode draws just 0.68 μA when RTC2 and LVD are active - critical for decade-long battery life. HALT mode consumes 112.5 μA/MHz during active operation, and SNOOZE enables selective peripheral wake-up (e.g., UART RX) while CPU remains halted, balancing responsiveness and power savings.
Can the R5F111MGGFB#30 perform simultaneous analog-to-digital conversion and background data flash writes?
Yes, the R5F111MGGFB#30 supports concurrent operation: its 12-bit A/D converter can sample analog inputs while the data flash memory is rewritten in background operation (BGO) mode. This allows real-time sensor logging (e.g., temperature history) without interrupting application code execution - essential for uninterrupted HMI responsiveness in industrial monitors.
