R5F100GEAFB#10 - 16-Bit RL78/G13 MCU, 64KB Flash, 48-LFQFP | Renesas
MPN: R5F100GEAFB#10 ✓ Hoạt độngR5F100GEAFB#10 Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and peripheral interfaces into one package. Within the broader semiconductor taxonomy, the R5F100GEAFB#10 belongs to the 16-bit MCU category (a mid-range between 8-bit entry devices and 32-bit ARM Cortex-M cores), and specifically to the RL78 sub-family (a proprietary Renesas low-power ISA succeeding the legacy 78K and R8C families) targeting ultra-low-power embedded applications.
Key specifications include: 66 uA/MHz active current, 230 nA STOP-mode standby current, 1.6 V to 5.5 V supply range, 4KB data flash and 4KB SRAM, hardware multiplier/divider, multiple low-power modes (HALT, STOP, SNOOZE), and an on-chip oscillator. The device also includes a real-time clock, watchdog timer, 12-bit SAR ADC, and serial interfaces (CSI/UART/I2C) that reduce external BOM and PCB area.
Architecturally, the RL78 uses a three-stage pipelined CISC core with a 16-bit ALU and 24-bit address space, paired with separate code-flash and data-flash regions and a tightly-coupled memory controller. The CSI (Clocked Serial Interface) and UART can run concurrently from different clocks, while SNOOZE mode allows selective peripheral wake-up without full CPU restart, enabling typical current consumption under 1 uA in always-on sensor systems.
Typical applications include white-goods control boards (washing machines, dishwashers, microwave ovens), battery-powered sensor nodes, HVAC controllers, motor-control front-ends, smart meters, and industrial sensor hubs. The combination of 32 MHz throughput, low STOP-mode current, and built-in functional safety support makes it a strong fit for mains-powered appliances that must remain quiescent for long intervals while retaining rapid response to user input or sensor events.
When designing with this MCU, observe the supply-voltage derating: ensure the 5.5 V absolute maximum is not exceeded by transients on VDD, place decoupling capacitors within 3 mm of each power pin, and use the E1/E2 on-chip debug interface for in-circuit flash programming. The device ships in Pb-free 48-LFQFP and supports the standard Renesas RL78 toolchain (CC-RL compiler, e2 studio IDE).

Ứng dụng tiêu biểu
R5F100GEAFB#10 phù hợp cho 7 Áp dụngs: Household Appliance Control (White Goods), Battery-Powered IoT Sensor Nodes, Smart Metering and Sub-Metering, HVAC Climate Control, Motor Control Front-End (BLDC Stepper), Industrial Sensor Hubs and PLC I/O, Consumer Electronics Remote Controls.
Household Appliance Control (White Goods)
The R5F100GEAFB#10's 64 KB code flash and IEC/UL 60730 hardware safety function make it ideal for controlling washing machines, dishwashers, microwave ovens, and induction cooktops. Its 230 nA STOP-mode current allows mains-powered boards to remain quiescent while waiting for keypad or sensor interrupts, and the 12-bit ADC directly reads temperature, water-level, and voltage-sense signals without external signal conditioning. Place decoupling within 3 mm of the VDD pins and use the E1 debug interface for in-field firmware updates during service.

Battery-Powered IoT Sensor Nodes
The R5F100GEAFB#10's 66 uA/MHz active current and 230 nA STOP-mode standby make it well-suited for coin-cell-powered wireless sensor nodes measuring temperature, humidity, or motion. With SNOOZE-mode peripheral wake-up, the MCU can poll a sensor or UART without restarting the CPU, achieving sub-1 uA average current in duty-cycled applications. The 48-LFQFP footprint keeps the design compact, and 64 KB code flash accommodates over-the-air firmware-update bootstraps plus application logic.
Được đề xuất
Smart Metering and Sub-Metering
Smart electricity, water, and gas meters use the R5F100GEAFB#10 for ADC-based measurement, RTC-driven tariff scheduling, and segmented LCD or LED display driving. The 4 KB data flash stores calibration coefficients and tampering event logs across long deployments, while the 32 MHz CPU executes metering algorithms at 0.1% accuracy. Hardware watchdog and IEC/UL 60730 safety functions support regulatory certification for utility-grade products.
Được đề xuất
HVAC Climate Control
The R5F100GEAFB#10's 12-bit SAR ADC, 1.6 V to 5.5 V supply range, and wide operating temperature cover HVAC wall thermostats and air-handler controllers. Multiple serial-interface modules (CSI, UART, I2C) connect to temperature/humidity sensors, CO2 modules, and WiFi/BLE transceiver modules. STOP-mode current around 230 nA keeps the standby power budget under 30 mW, even at 230 V mains supply-side consumption budget.
Được đề xuất
Motor Control Front-End (BLDC Stepper)
The R5F100GEAFB#10's hardware timers and PWM outputs suit low-power BLDC and stepper motor-control front-ends in fans, pumps, and small appliances. Programmable dead-time generators and high-speed timers provide deterministic commutation at 32 MHz, while the ADC samples back-EMF and current-sense signals with 12-bit resolution. Combined with a discrete gate-driver stage, this MCU achieves >90% efficiency at 200 W output levels.
Được đề xuất
Industrial Sensor Hubs and PLC I/O
Industrial sensor hubs use the R5F100GEAFB#10 to aggregate analog/digital sensor data, run local decision logic, and forward results over UART/CSI links. The wide 1.6 V-5.5 V supply tolerates regulated 24 V industrial bus rails stepped down by small DC-DC converters, while the -40 C to +85 C operating temperature covers unheated factory cabinets. Hardware CRC and watchdog timer ensure reliable long-term unattended operation in PLC I/O modules.
Được đề xuất
Consumer Electronics Remote Controls
The R5F100GEAFB#10 delivers ample 64 KB code flash for IR/RF-protocol stacks while its 230 nA STOP-mode current allows coin-cell-powered remote controls to last 5-7 years. On-chip 12-bit ADC supports capacitive-touch or resistive-button scanning without external components, and the 32 MHz CPU handles high-IR carrier modulation accurately. Programming via the E1 interface allows product differentiation by firmware without hardware changes.

Ghi chú thiết kế
Place a 0.1 uF X7R ceramic decoupling capacitor within 3 mm of each VDD pin and a bulk 1 uF capacitor on the same node. Add a ferrite bead in series with VDD for noisy 5 V supplies. The R5F100GEAFB#10 has a 5.5 V absolute maximum, so budget at least 10% margin below 5 V for hot-plug transients, especially in appliance mains environments with inductive kickback spikes.
While the 48-LFQFP has good thermal dissipation for a 64 KB flash MCU, the R5F100GEAFB#10 still draws up to 66 uA/MHz active current. Estimating: 32 MHz x 66 uA/MHz = 2.11 mA active power, which yields ~7 mW typical dissipation at 3.3 V. The 7x7 LFQFP thermal pad may be left unconnected for the LFQFP variant; consult the hardware manual before using it as a thermal pad.
Do not exceed 5.5 V on VDD under any load condition - transients from inductive loads and DC-DC switching supplies can damage the part. Ensure the E1/E2 debug interface signals TOOL0/TOOL1 are not driven by external sources during reset to avoid debug contention. Finally, when migrating firmware from R5F100GEAFB#V0 to #10, verify the watchdog timer interval configuration bits are matched.
Route the analog AVDD supply separately from noisy digital VDD with a ferrite bead or RC filter, even when both connect to the same source. Keep analog inputs (ANI0-ANI19) short and away from switching traces; use a ground-guard-pour to minimize digital coupling into ADC readings, especially for sensor measurements in metering and HVAC applications.
