Product details
Overview
R5F111MEAFB#10 from Renesas is an RL78/L1C 80-pin LQFP microcontroller without USB, featuring 64 KB flash, 8 KB RAM, integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (13-channel, VDD=2.4–3.6 V), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD display systems in consumer-grade metering and portable instrumentation.
For engineers reviewing the R5F111MEAFB#10 datasheet, R5F111MEAFB#10 pinout, R5F111MEAFB#10 application, or R5F111MEAFB#10 equivalent, key selection criteria include LCD segment drive capability, low-voltage analog performance (12-bit ADC at ≥2.4 V), absence of USB PHY, and compatibility with 80-pin LFQFP layout and Renesas' RL78 toolchain.
Technical Context
The R5F111MEAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @24 MHz or 30.5 μs @32.768 kHz). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods, with configurable segment/common outputs.
Its analog subsystem includes dual 8-bit D/A channels (0–VDD output), two comparators with selectable reference sources, and a 12-bit A/D converter operating only above 2.4 V - requiring careful power rail design when targeting full-resolution conversion. The device supports SNOOZE, STOP, and HALT low-power modes, with real-time clock (RTC2) and LVD enabled during sub-μA retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MGAFB#10 | 128 KB flash, 10 KB RAM, same 80-pin LFQFP package and peripheral set | Supports larger firmware (e.g., added communication stacks or encryption libraries) | Select when future firmware expansion or OTA update capability is required |
| R5F110MEAFB#10 | Identical 64 KB flash/8 KB RAM spec but includes USB 2.0 function controller (full-speed/low-speed) | Enables PC connectivity for configuration or data export; adds UREGC/UVBUS/UDP/UDM pins and USB regulator | Choose only if USB host/device interface is mandatory; requires additional USB decoupling and layout care |
Compared with R5F111MGAFB#10, the R5F111MEAFB#10 trades flash headroom for cost-sensitive designs; versus R5F110MEAFB#10, it removes USB complexity and associated power/PCB overhead - making it optimal for standalone, ultra-low-power LCD applications where wired PC interface is unnecessary.

FAQ
Does R5F111MEAFB#10 support USB functionality?
No, R5F111MEAFB#10 is part of the "111" series, which explicitly excludes USB. Only "110" series variants (e.g., R5F110MEAFB#10) integrate the USB 2.0 function controller. The R5F111MEAFB#10 omits UREGC, UVBUS, UDP, and UDM pins entirely and has no USB-related registers or firmware support.
What is the maximum segment count supported by R5F111MEAFB#10's LCD controller?
The R5F111MEAFB#10 supports up to 44 segment outputs and 4 common outputs in its 80-pin configuration. This is confirmed in Section 1.1 (Features) and Figure 1-1 of the datasheet, which specifies "Segment signal output: 44 (40) to 56 (52)" - with the lower value applying to 80-pin devices. Segments are mapped across dedicated pins (e.g., SEG0–SEG6, SEG12–SEG25) and cannot be reassigned to GPIO.
Can the 12-bit A/D converter in R5F111MEAFB#10 operate at 1.8 V supply?
No. The 12-bit A/D converter in R5F111MEAFB#10 requires VDD ≥2.4 V, as explicitly stated in Section 1.1: "12-bit resolution A/D converter (VDD = 2.4 to 3.6 V)". At 1.8 V, only the 8/10-bit mode is functional. Designers must ensure regulated 2.4–3.6 V supply when using 12-bit precision - critical for accurate sensor measurements in the R5F111MEAFB#10.
Is R5F111MEAFB#10 qualified for industrial temperature range (−40 to +105°C)?
No. R5F111MEAFB#10 carries the "A" suffix in its ordering code (R5F111MEAFB), indicating Consumer grade with operating ambient temperature of −40 to +85°C only. Industrial-grade variants use the "G" suffix (e.g., R5F111MEGFB) and are physically distinct orderable parts - the R5F111MEAFB#10 is not rated or tested for +105°C operation.
What debug interface does R5F111MEAFB#10 support?
R5F111MEAFB#10 supports Renesas' on-chip debug system via the TOOL0 pin (pin 40), used for bidirectional serial communication with E2 emulator or compatible debuggers. It does not support SWD or JTAG; debugging requires Renesas-specific tools and the TOOL0/TOOLRxD/TOOLTxD signal routing defined in the pinout - no external debug header is needed due to single-pin minimal interface.
