R5F10WMGAFB#30 - RL78/L13 16-bit MCU 128KB Flash | Renesas
MPN: R5F10WMGAFB#30 ✓ Hoạt độngR5F10WMGAFB#30 Tóm tắt
An RL78 microcontroller is a low-power 16-bit CISC core designed by NEC/Renesas as the successor to the 78K0 family. RL78 cores are tightly integrated with precision analog, LCD segment drivers, and multiple low-power operating modes. The RL78/L13 sub-family is the dedicated variant for applications with on-glass or on-board segment LCD displays, sitting within Renesas's broader RL78 product pyramid: RL78 core -> RL78/L1x (LCD) -> RL78/L13 (mid-density). This positioning makes the part a benchmark for years-of-battery-life white goods.
Key features include three on-chip low-speed on-chip oscillators (15 kHz, 32 kHz, and the main 24 MHz high-speed on-chip oscillator), a 5-channel internal voltage booster for LCD bias, hardware multiplier/divider, 10-bit successive-approximation ADC, and a rich serial complement (CSI/SPI, UART, I2C, and LIN-bus). Power consumption is exceptionally low: approximately 0.6 µA in STOP retention mode with the LCD operating on a 32 kHz subclock and only ~3 mA active at 24 MHz.
Architecturally, the RL78/L13 pairs a 3-stage pipeline CISC core with separated code/data buses (Harvard-style) and is built on a 130 nm mixed-signal process with embedded EEPROM/Flash. The integrated LCD controller supports up to 35 segment outputs x 4 common (or 39 x 8) configurations, configurable bias and frame frequency, and internal charge-pump or resistor-divider bias generation to allow operation from a single 1.8 V to 5.5 V supply.
Typical applications include white-good HMI boards (washing-machine, microwave, induction-cooktop panels), residential gas/water/heat meters with display, blood-pressure and household medical displays, and remote-control units with battery charging indication.
When designing with the R5F10WMGAFB#30, place the decoupling capacitors as close as possible to the VDD/VSS pins and reserve at least one full PCB layer for the LCD segment-trace routing. Selecting the correct bias source (internal resistor divider vs external capacitor divider) is critical - misconfiguring the charge pump on high-multiplex panels causes ghost segments.

Ứng dụng tiêu biểu
R5F10WMGAFB#30 phù hợp cho 6 Áp dụngs: White-Goods HMI (Washing Machine Front Panel), Residential Gas / Water / Heat Meter Displays, Microwave / Oven HMI Display, Blood Pressure / Household Medical Display, Induction Cooktop User Interface Panel, Battery-Powered Remote / Thermostat Display.
White-Goods HMI (Washing Machine Front Panel)
The R5F10WMGAFB#30's integrated segment-LCD controller drives up to 39 segments x 8 commons, suiting the multi-icon front panels found in modern washing machines. Its 0.6 µA STOP-retention current allows coin-cell backup of cycle memory during power-down. The RL78 16-bit core runs the user-interface, motor-state UI, and Wi-Fi indicator segments, while sub-microamp sleep preserves battery-backed fault logs.
Được đề xuất
Residential Gas / Water / Heat Meter Displays
The R5F10WMGAFB#30's 1.8-5.5 V range allows direct operation from a single lithium AA cell for 10+ years, while its sub-microamp STOP+LCD retention keeps the consumption readout visible even during mains fail. The Renesas RL78/L13 LCD charge pump generates a stable display bias independent of battery droop, eliminating the flickering seen on meter modules using discrete drivers.
Được đề xuất
Microwave / Oven HMI Display
Microwave ovens need a 16-bit core for clock + relay control plus a multi-segment LCD for time/menu display; the RL78/L13 packs both onto a single 12x12 mm BGA-friendly LQFP-80. The internal charge pump allows the panel to remain readable across temperature swings where competing discrete bias networks drift. With internal 24 MHz HOCO, the part also drives the inverter control PWM signals for the magnetron.
Được đề xuất
Blood Pressure / Household Medical Display
Battery-powered home-medical devices require long idle and stable LCD readout; the R5F10WMGAFB#30's 0.6 µA STOP current and integrated LCD driver comply with battery-life targets on AA cells. Its 10-bit SAR ADC samples cuff pressure, while the RL78 core computes systolic/diastolic values and updates the segment display under sub-microamp power.
Được đề xuất
Induction Cooktop User Interface Panel
The R5F10WMGAFB#30 controls slider/segment LCD UI on induction cooktops where the part sits behind an isolated IGBT-driver section. The RL78's high-ESD tolerance and 1.8 V low-voltage operation tolerate wide supply ripple from the switching PFC stage. Five-channel LCD bias simplifies the 7-segment level indicator used in cooking programs.
Được đề xuất
Battery-Powered Remote / Thermostat Display
Remotes and thermostats run for years on two AAA cells - the R5F10WMGAFB#30's STOP+LCD retention of 0.6 µA preserves the temperature readout on a segment LCD while still waking up under a button interrupt within microseconds. The 24 MHz HOCO handles UART communication back to the boiler/HVAC controller without sacrificing battery life.

Ghi chú thiết kế
Routing the 39 segment outputs and 8 commons on an 80-LQFP requires a dedicated inner-layer route; keep COM lines on a single layer and route SEG lines orthogonal. Crosstalk on adjacent SEG traces shows up as a ghost-segment artifact on large multiplex (>1/4 bias) panels. The Renesas RL78/L13 hardware manual recommends 4-6 kohm SEG driver impedance for a 4-inch-class display; below this number the contrast drops at low battery.
Configuring the LCD bias source incorrectly is the most common cause of factory-line rework on the R5F10WMGAFB#30. The internal capacitor divider (VLCD pins with external 1uF caps) and internal resistor divider are mutually exclusive options set by the LCD register block; selecting both simultaneously powers the LCD controller in an undefined state and resets the core. Verify the VLCO/VLCD/VSS1/VSS2 cap network per the hardware manual's bias-selection matrix before firmware bring-up.
At 24 MHz HOCO active and 5 V supply, the R5F10WMGAFB#30 dissipates approximately 15 mW typ; with the SEG drivers fully loaded the additional dynamic current adds another 3-5 mW. Estimated junction rise using LQFP-80 12x12 theta_JA ~50 C/W is <1 C even in a sealed enclosure. No external heatsinking is required for home-goods HMI design - but do not place the part adjacent to a TRIAC heat sink on induction-cooktop PCBs.
Place the bypass capacitor on VDD (1uF ceramic) within 3 mm of pin 9 to keep reset transients below 0.5 VPP on a single 1.8 V supply. Add a 100 nF cap parallel on the VSS pin at pin 10 to suppress LCD driver switching noise from coupling into the analog supply. RESET pin 48 requires a 100 kohm external pull-up to VDD and a 100 nF cap to ground for stable cold-start behavior.
