It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and supports true low-power operation down to 71 μA/MHz (HALT mode) and 0.61 μA in RTC+LVD STOP mode - optimized for battery-powered LCD-based metering and control panels.
For engineers reviewing the R5F10WMEGFB#10 datasheet, R5F10WMEGFB#10 pinout, R5F10WMEGFB#10 application, or R5F10WMEGFB#10 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + I²C + CSI interfaces, 12-channel 10-bit ADC, and industrial-grade −40°C to +105°C temperature rating with embedded LVD and RTC2 calendar support.
Technical Context
The R5F10WMEGFB#10 implements the RL78 CPU core with a 3-stage CISC pipeline, 1 MB address space, and selectable high-speed on-chip oscillator (1–24 MHz ±1.0%). Its peripheral set includes an 8-channel 16-bit timer array (TAU), 1-channel 16-bit timer KB20, 12-bit interval timer, real-time clock 2 with calendar and alarm, and 2-channel comparator with internal/external reference selection.

FAQ
What is the maximum LCD segment count supported by the R5F10WMEGFB#10?
The R5F10WMEGFB#10 supports up to 51 segment outputs and 8 common outputs when configured for 8-common operation. This configuration enables driving large alphanumeric or custom symbol displays commonly used in utility meters and industrial panels. The LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods - allowing flexible bias generation without external components.
Does the R5F10WMEGFB#10 include a hardware real-time clock with calendar function?
Yes, the R5F10WMEGFB#10 integrates Real-Time Clock 2 (RTC2) with full calendar functionality supporting dates up to 99 years, alarm interrupts, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock and maintains timekeeping at just 0.61 µA - enabling accurate timestamping in battery-powered applications without external RTC ICs.
What communication interfaces are available on the R5F10WMEGFB#10?
The R5F10WMEGFB#10 provides three UART channels (one LIN-bus compatible), one I²C interface (IICA), two CSI modules (SPI-like serial interfaces), and one additional I²C serial interface (IIC00/IIC10). These interfaces support simultaneous communication with sensors, displays, wireless modules, and host controllers - with peripheral I/O redirection enabling flexible pin assignment for routing signals to optimal locations on the PCB.
Can the R5F10WMEGFB#10 operate from a single 1.8 V supply?
Yes, the R5F10WMEGFB#10 supports operation from 1.6 V to 5.5 V across its full industrial temperature range (−40°C to +105°C). At 1.8 V, it can run the high-speed on-chip oscillator up to 16 MHz and maintain full peripheral functionality including LCD driving, ADC, and communication interfaces - making it suitable for coin-cell or single-LiFePO₄ powered devices where low-voltage operation is critical.
How does the R5F10WMEGFB#10 handle analog sensing and signal comparison?
The R5F10WMEGFB#10 integrates a 12-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, plus two independent comparators with selectable internal/external reference inputs and configurable modes (high-speed, low-speed, or window). This enables direct analog front-end processing - such as battery voltage monitoring, thermistor reading, or overcurrent detection - without external op-amps or reference ICs, reducing system complexity and component count.
