R5F10WLGAFB#30 概要
What is a 16-bit MCU? A 16-bit microcontroller (MCU) is a single-chip computer that processes instructions and data over a 16-bit data bus, sitting between 8-bit entry-level MCUs (e.g., PIC16, ATmega) and 32-bit Cortex-M parts in the embedded hierarchy. The RL78 core extends this category with an enhanced three-stage pipeline, ultra-low-power RUN/STOP/HALT/SNOOZE modes, and on-chip peripherals like 12-bit ADCs, comparators, and segment LCD controllers — placing it under the broader taxonomy: MCU -> microcontroller -> embedded processor -> semiconductor IC. The RL78/L13 sub-family specifically targets segment-LCD human-machine-interface applications.
Key features include 128 KB (128K x 8) flash program memory, configurable RAM/data flash, a 24 MHz maximum CPU clock, an integrated segment LCD driver (up to 8 common x 40 segment), a 12-bit A/D converter with up to 12 channels, multiple low-power modes (STOP, HALT, SNOOZE), and a wide 1.6 V–5.5 V operating range. Per the Renesas product page, this part is suitable for LCD display of home appliances or measurement devices, and it operates over the -40 °C to +85 °C industrial temperature range.
From an architectural standpoint, the RL78 core uses a Harvard-style bus with separate program flash and SRAM paths, supports the 78K0R-compatible instruction set, and provides hardware multiply/divide plus a low-power on-chip oscillator that removes the need for an external crystal in many designs. The on-chip segment LCD driver generates the necessary AC bias waveforms internally, eliminating external charge-pump circuitry for static, 1/3, and 1/4 duty LCD glass.
Typical applications include home appliance control boards (washing machines, microwave ovens, induction cookers), smart electricity/water/gas meters, HVAC thermostats, white-good user-interface panels, industrial measurement equipment with segment LCD readouts, and battery-powered sensor readouts. The integrated segment LCD driver reduces BOM by replacing external LCD bias ICs.
When designing with this device, plan for decoupling capacitors near the VDD/VSS pins, leave the TOOL0 pin accessible for in-circuit debugger connection, and verify the segment/comment pin assignment matches your LCD glass map in the e2 studio / CS+ pin configurator. Power sequencing and SNOOZE-mode entry are configured in the Smart Configurator code-generation toolchain rather than via runtime registers.

主な用途
R5F10WLGAFB#30 の用途: 6 件s: Home Appliance Control Board, Smart Electricity/Water/Gas Meter, HVAC Thermostat with Segment LCD, White-Goods User-Interface Panel, Industrial Measurement Equipment, Battery-Powered Sensor Readout.
Home Appliance Control Board
The R5F10WLGAFB#30's integrated segment-LCD driver and 1.6–5.5 V supply range make it ideal for home appliance HMI boards (washing machines, microwave ovens, dishwashers, induction cookers). With 128 KB flash it fits feature-rich control algorithms plus bootloader, and the RL78 core's low STOP current (microamp range per datasheet) lets front-panel controllers idle for years on a coin cell. Drop the MCU between the mains-isolated supply and the 4- or 8-common segment glass to drive user feedback without a separate LCD bias IC.
おすすめ
Smart Electricity/Water/Gas Meter
The R5F10WLGAFB#30 is purpose-built for metering applications per the Renesas product description. Its on-chip segment-LCD driver removes external charge-pump parts in static and 1/3-duty LCD glass, while 128 KB flash stores calibration tables and tamper logs. The RL78 STOP/SNOOZE modes preserve battery life between measurement intervals; combined with the 24 MHz core for 32x16 multiply-accumulate in energy algorithms, it delivers metrology-grade accuracy from a single 3 V lithium cell.
おすすめ
HVAC Thermostat with Segment LCD
The R5F10WLGAFB#30's wide 1.6–5.5 V operating range handles the 24 VAC thermostat supply down to 2-AAA battery backup, and the integrated segment-LCD controller displays temperature, setpoint, and mode icons without external drivers. The 24 MHz core runs PID control loops at sub-millisecond intervals, while the 12-bit A/D reads thermistor/resistive temperature sensors directly. Operating over -40 °C to +85 °C covers attic and basement HVAC deployments.
おすすめ
White-Goods User-Interface Panel
Front-panel control modules for refrigerators, ovens, and water heaters benefit from the R5F10WLGAFB#30's on-chip segment-LCD driver — eliminating the BOM and PCB area of a dedicated LCD bias generator. The 128 KB flash accommodates multi-language UI tables and firmware update logic, and RL78's HALT mode draws tens of microamps, allowing always-on user input sensing with negligible standby consumption. The 64-LFQFP gives plenty of GPIO for capacitive touch keys and rotary encoder inputs.
おすすめ
Industrial Measurement Equipment
For industrial gauges and measurement instruments, the R5F10WLGAFB#30 provides 128 KB flash for calibration constants and logging, 12-bit ADC for analog sensor interfaces, and the integrated segment-LCD controller for direct display of measured values. The -40 °C to +85 °C industrial temperature range ensures reliable operation in factory environments. The 24 MHz core computes filter/FFT algorithms in real time, while SNOOZE mode enables battery-backed portable measurement tools.
おすすめ
Battery-Powered Sensor Readout
Field sensor readouts and remote monitoring nodes benefit from the R5F10WLGAFB#30's ultra-low STOP current and wide 1.6 V supply range — perfect for 1x or 2x AA alkaline cells. The integrated segment-LCD driver displays sensor values without an external bias IC, reducing both BOM and quiescent draw. The 12-bit ADC and 24 MHz RL78 core handle periodic sensor reads, filtering, and LCD updates while spending most of the time in HALT/STOP for multi-year battery life.

設計ノート
The R5F10WLGAFB#30 supports RL78 STOP, HALT, and SNOOZE modes for ultra-low-power operation. STOP current is typically sub-microamp per the Renesas RL78/L13 group datasheet; SNOOZE mode lets the A/D converter run while the CPU is stopped, ideal for periodic battery-powered sensor reads. Place a 0.1 µF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair, and add a 10 µF bulk capacitor near the supply pin to handle inrush during LCD glass transitions.
Route the segment-LCD traces in a star pattern from the SEG/COM pins and keep them away from switching power and high-speed digital lines to avoid display ghosting. The TOOL0 pin must remain accessible for in-circuit debugger/programmer connection — do not place it on an inner layer. The LFQFP-64 10x10 mm package has a thermal pad that should be soldered to a copper pour to improve heat dissipation for hot-spot reliability, even though RL78 parts run cool.
Do not exceed 5.5 V on VDD or apply reverse polarity — the RL78 family has no internal reverse-protection. Always configure unused pins via the Smart Configurator / e2 studio code generator as outputs with low-level drive rather than floating inputs, which can cause spurious interrupt wakeups from STOP mode. Confirm the segment-LCD glass COM/SEG assignment matches the pin configurator output before ordering PCBs — a one-bit map error typically requires a board rework.
The R5F10WLGAFB#30 benefits from the RL78 core's low EMI signature (3-stage pipeline, modest 24 MHz clock). For CE/FCC Class B compliance, place a ferrite bead on the supply feed, keep segment-LCD traces short and matched, and consider a 100 Ω RC snubber on relay/triac outputs driven by MCU GPIOs. Use the internal HOCO (24 MHz) instead of an external crystal when EMI margin is tight — eliminating the crystal removes a key radiated-emissions source.
