Product details
Overview
R5F111MEAFB#30 from Renesas is an RL78/L1C 8-bit MCU with integrated LCD controller/driver, 12-bit A/D converter, and true low-power operation (112.5 μA/MHz active, 0.68 μA RTC2+LVD). It features 64 KB Flash, 8 KB Data Flash, 8 KB RAM, operates from 1.6–3.6 V, and targets battery-powered LCD display applications such as smart meters and portable medical devices.
For engineers reviewing the R5F111MEAFB#30 datasheet, R5F111MEAFB#30 pinout, R5F111MEAFB#30 application, or R5F111MEAFB#30 equivalent, key selection criteria include its 80-pin LFQFP package, absence of USB functionality, segment/common LCD drive capability (up to 44 segments / 4 commons), ultra-low power modes (HALT/STOP/SNOOZE), and support for 12-bit ADC at 2.4–3.6 V.
Technical Context
The R5F111MEAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 33 DMIPS at 24 MHz. It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods, with configurable segment outputs (SEG0–SEG55) and common outputs (COM0–COM7).
Peripheral integration includes four UART/LIN channels, five I²C/simplified I²C channels, four CSI/SPI channels, eleven 16-bit timers, one 12-bit interval timer, RTC2 with calendar and alarm, and two comparators. Its DTC and ELC enable efficient event-driven data movement without CPU intervention.

Applications
| Smart Energy Metering | Portable Medical Devices |
|---|---|
|
Use Scenario: Battery-powered electricity/water/gas meter with segmented LCD display and sensor telemetry. IC Role / Device Role / Timing Role: Main system controller managing LCD refresh, metrology ADC sampling, RTC-based billing intervals, and low-power wake-up scheduling. Use Value: Ultra-low STOP-mode current (0.68 μA) extends battery life beyond 10 years; integrated LCD driver reduces BOM count by one IC. |
Use Scenario: Handheld blood glucose monitor or pulse oximeter with alphanumeric LCD and analog sensor front-end. IC Role / Device Role / Timing Role: Sensor signal acquisition (12-bit ADC), LCD rendering, button/key scan (KR0–KR7), and buzzer feedback (PCLBUZ0/1). Use Value: Single-chip solution eliminates external LCD driver and precision reference; 12-bit ADC resolves sub-millivolt sensor variations. |
| Home Appliance Control Panels | Industrial HMI Displays |
|
Use Scenario: Microwave oven or washing machine control panel with 4-digit LCD and touch-key interface. IC Role / Device Role / Timing Role: Key return scanning (KR0–KR7), segment driving (SEG0–SEG55), buzzer tone generation, and real-time cooking timer (RTC2). Use Value: On-chip key interrupt and programmable clock/buzzer outputs reduce external components; HALT mode cuts standby power during idle periods. |
Use Scenario: Panel-mounted industrial status display with environmental monitoring (temperature/humidity) and local alarm indication. IC Role / Device Role / Timing Role: Dual ADC channel acquisition, LCD update synchronization, LVD fault detection, and watchdog supervision of critical processes. Use Value: 12-level LVD interrupt/reset ensures reliable brown-out response; -40°C to +85°C operating range meets industrial ambient requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MGAFB#30 | 128 KB Flash, 10 KB RAM, same 80-pin LFQFP package and peripheral set | Supports larger firmware (e.g., enhanced UI stacks or communication protocols) without layout change | Select when future firmware expansion or additional feature integration is anticipated |
| R5F111NEALA#U0 | 85-pin VFLGA (7 × 7 mm), same 64 KB Flash but different package and pinout | Targeted at space-constrained designs where footprint reduction outweighs rework cost | Choose only if PCB area savings justify redesign; not pin-compatible with R5F111MEAFB#30 |
Compared with R5F111MGAFB#30, R5F111MEAFB#30 trades Flash/RAM capacity for lower cost and smaller memory footprint in fixed-function LCD applications; versus R5F111NEALA#U0, it offers proven manufacturability in LFQFP and avoids VFLGA assembly complexity.

FAQ
Does R5F111MEAFB#30 include USB functionality?
No, R5F111MEAFB#30 is part of the "products without USB" family within the RL78/L1C series. Its orderable part number begins with "R5F111", confirming absence of USB 2.0 controller, UREGC, UBUS, UDP, and UDM pins. For USB-enabled variants, refer to R5F110xxx series parts.
What LCD segment and common drive capability does R5F111MEAFB#30 support?
R5F111MEAFB#30 supports up to 44 segment outputs and 4 common outputs (or 52 segments / 8 commons in extended configurations). Validated segment pins include SEG0–SEG6, SEG12–SEG25, SEG27–SEG42, and SEG48–SEG55; COM0–COM3 are designated common outputs per datasheet Figure 1-2.
What is the maximum ADC resolution and required supply voltage for full accuracy?
The R5F111MEAFB#30 supports 12-bit A/D conversion, but this resolution is guaranteed only when VDD is between 2.4 V and 3.6 V. At lower supply voltages (1.6–2.4 V), the ADC operates at 8/10-bit resolution. Internal reference voltage is 1.45 V (typical), enabling precise ratiometric measurements.
Is R5F111MEAFB#30 pin-compatible with other RL78/L1C 80-pin variants?
Yes, all RL78/L1C 80-pin LFQFP variants-including R5F111MEAFB#30, R5F111MGAFB#30, and R5F111MHAFB#30-share identical pinout, package dimensions (12 × 12 mm), and pitch (0.5 mm). Function allocation per pin is consistent; differences lie only in memory size and enabled peripherals.
What low-power modes are available on R5F111MEAFB#30 and their typical current draw?
R5F111MEAFB#30 supports HALT, STOP, and SNOOZE modes. HALT halts CPU while preserving RAM/peripherals (current depends on clock source). STOP disables all clocks except RTC2/LVD (0.68 μA typical). SNOOZE allows selective peripheral operation during low-power sleep, ideal for periodic sensor polling without full wake-up.
