Product details
Overview
R5F111MGAFB#30 from Renesas is an RL78/L1C 80-pin low-power MCU with integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (12-channel, VDD = 2.4–3.6 V), and 96 KB flash/8 KB data flash/10 KB RAM. It operates from 1.6–3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD-based metering and control panels.
For engineers reviewing the R5F111MGAFB#30 datasheet, R5F111MGAFB#30 pinout, R5F111MGAFB#30 application, or R5F111MGAFB#30 equivalent, key selection criteria include ultra-low power modes (0.68 μA RTC2+LVD), on-chip LCD bias generation, USB absence (vs. RL78/L1C 110-series), and 80-pin LFQFP package compatibility with existing LCD interface layouts.
Technical Context
The R5F111MGAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs @24 MHz to 30.5 μs @32.768 kHz). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor-split, or external resistor-divider bias methods.
Peripheral integration includes four UART/LIN channels, five I²C interfaces, four CSI/SPI channels, eleven 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, and two 8-bit D/A outputs. The device lacks USB functionality-confirmed by its "111" prefix and omission of UREGC/UVBUS/UDP/UDM pins in the 80-pin non-USB pinout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MHAFB#30 | 128 KB flash, 12 KB RAM, same 80-pin LFQFP package and peripheral set | Supports larger firmware (e.g., enhanced encryption, OTA bootloader) without layout change | Select when future firmware growth or added security features require >96 KB code space |
| R5F111NGAFB#30 | 85-pin VFLGA (7 × 7 mm), identical memory and peripherals but different package and pinout | Suitable for space-constrained designs where 80-pin QFP footprint is unavailable | Choose only if board redesign accommodates VFLGA and revised routing for 85-pin mapping |
Compared with R5F111MGAFB#30, R5F111MHAFB#30 offers headroom for feature-rich firmware while maintaining pin compatibility, whereas R5F111NGAFB#30 trades package size for incompatible pin assignment - requiring full PCB revision despite identical functional capability.

FAQ
Does R5F111MGAFB#30 support USB functionality?
No, R5F111MGAFB#30 does not support USB. Its part number prefix "111" explicitly denotes the USB-disabled variant of the RL78/L1C family. The datasheet confirms absence of UREGC, UVBUS, UDP, and UDM pins in the 80-pin non-USB configuration. For USB-enabled operation, select the "110" series such as R5F110MGAFB#30.
What LCD configurations does R5F111MGAFB#30 support?
R5F111MGAFB#30 supports three LCD bias methods: internal voltage boosting, capacitor-split, and external resistance division. It drives up to 44 segments and 4 commons (or 40 segments and 8 commons), with dedicated VL1–VL4 power supplies and CAPH/CAPL terminals for capacitor-based bias networks.
What is the maximum A/D conversion resolution and input range for R5F111MGAFB#30?
R5F111MGAFB#30 provides 12-bit A/D conversion with 12 analog inputs (ANI0–ANI2, ANI16–ANI21) when VDD is 2.4–3.6 V. At lower VDD (1.6–2.4 V), resolution drops to 8/10 bits. Internal reference voltage is TYP. 1.45 V, and the on-chip temperature sensor is factory-calibrated.
Is R5F111MGAFB#30 pin-compatible with other RL78/L1C 80-pin variants?
Yes, R5F111MGAFB#30 shares identical 80-pin LFQFP pinout and electrical characteristics with all other RL78/L1C 80-pin non-USB parts (e.g., R5F111MEAFB#30, R5F111MHAFB#30). Memory size and peripheral enablement differ, but PCB layout remains unchanged across this package group.
What low-power modes are available on R5F111MGAFB#30 and their typical current draw?
R5F111MGAFB#30 offers HALT (112.5 μA/MHz), STOP (0.68 μA with RTC2 + LVD active), and SNOOZE modes. STOP mode retains RAM and RTC2 state while disabling CPU and most peripherals - ideal for long-duration sleep between display updates or sensor reads in battery-powered systems.
