R5F10RJAAFA#V0 - 16KB Flash 16-bit LCD MCU | Renesas
MPN: R5F10RJAAFA#V0 ✓ Hoạt độngR5F10RJAAFA#V0 Tóm tắt
The R5F10RJAAFA#V0 belongs to the RL78 family of microcontrollers, a 16-bit CISC architecture developed by Renesas as a low-power successor to the 78K and R8C families. An MCU (microcontroller unit) is a single-chip computer integrating CPU, memory, and peripherals; the RL78/L12 sub-series specifically targets small appliances, healthcare devices, and other cost-sensitive LCD-based applications where ultra-low standby current is critical.
Key features include True Low Power Platform technology achieving 75 µA/MHz active current and 0.64 µA for RTC + LVD standby, three selectable LCD driving voltage generation methods (external resistance division, capacitive split, and internal voltage boost), and integrated safety peripherals. The 16-bit CISC core delivers 31 DMIPS at 24 MHz while consuming a fraction of the power of competing 8/16-bit cores.
The architecture uses a Harvard-style bus with unified register bank that lets the compiler treat ROM, RAM, and SFRs as one address space, accelerating context switching and interrupt response. A built-in 8-channel 10-bit ADC, multiple timers, RTC, UART, I2C, and CSI simplify BOM cost by eliminating external chips. The device supports 4.5 KB RAM plus 2 KB data flash for non-volatile user storage.
Typical applications include white goods (washing machines, microwave ovens), healthcare devices (blood-pressure monitors, glucose meters), industrial segment-LCD instrumentation, smart thermostats, and battery-powered consumer electronics. The wide 1.6 V – 5.5 V supply range lets the same part run from a single 3 V coin cell or a regulated 5 V rail.
When designing with the R5F10RJAAFA#V0, choose the LCD driving method based on panel size: capacitive split for small panels, internal voltage boost for medium panels up to 5 V, and external resistor division for large panels or when precise contrast adjustment is required. The TOOLCHAIN is supported by the free e2 studio IDE plus the CC-RL compiler.

Ứng dụng tiêu biểu
R5F10RJAAFA#V0 phù hợp cho 6 Áp dụngs: White Goods - Washing Machine Control Board, Blood Pressure Monitor / Healthcare Device, Microwave Oven / Kitchen Appliance, Smart Thermostat, Industrial Segment-LCD Instrumentation, Battery-Powered Consumer Electronics.
White Goods - Washing Machine Control Board
The R5F10RJAAFA#V0 is well-suited for washing machine control boards, where the integrated segment LCD controller/driver drives a 40+ segment display for cycle status, temperature, and remaining time without an external driver IC. Its 24 MHz RL78 core delivers 31 DMIPS, enough to manage motor control state machines, water-level sensing, and user interface. The 1.6 V to 5.5 V range lets the part ride the same 5 V rail used by the relay drivers, reducing BOM. Active current of 75 µA/MHz and 0.64 µA standby keep total board consumption well within the energy-budget envelope.

Blood Pressure Monitor / Healthcare Device
The R5F10RJAAFA#V0 fits blood-pressure monitors and similar healthcare devices as Renesas explicitly lists this market on the product page. The 0.64 µA RTC+LVD standby current preserves battery life between infrequent measurements, while the integrated LCD controller drives a multi-digit segment display showing systolic/diastolic/pulse. The wide 1.6 V to 5.5 V supply range supports two-AA battery designs or a single 3 V coin cell. On-chip 10-bit ADC and CSI/I2C peripherals interface to pressure sensors and BLE modules for connectivity variants.
Được đề xuất
Microwave Oven / Kitchen Appliance
The R5F10RJAAFA#V0's integrated segment LCD controller/driver and 75 µA/MHz active current make it a strong fit for microwave oven control boards. The RL78 core handles keypad scanning, magnetron timing, buzzer control, and child-lock state machines at 24 MHz while drawing under 2 mA active. Three selectable LCD driving methods let designers pick capacitive split for compact displays or internal voltage boost for higher-contrast panels without external components. Industrial -40 C to +85 C temperature range covers kitchen-cabinet thermal environments.
Được đề xuất
Smart Thermostat
The R5F10RJAAFA#V0 powers smart-thermostat user-interface boards where the segment LCD shows set-point temperature, mode, and fan status. The 16 KB flash comfortably fits HVAC state-machine firmware plus optional scheduling logic. Wide 1.6 V to 5.5 V supply accepts the 24 VAC half-wave rectified input commonly used in HVAC control. The 0.64 µA standby current prevents battery drain during power-loss backup operation. Multiple CSI/UART interfaces allow connection to the main Wi-Fi/BLE module for IoT connectivity.
Được đề xuất
Industrial Segment-LCD Instrumentation
The R5F10RJAAFA#V0 targets industrial panel meters, process indicators, and test equipment with segment LCD readouts. The RL78's 16-bit arithmetic and 24 MHz clock handle RMS calculation, linearization, and averaging algorithms for transducer conditioning. Industrial -40 C to +85 C operation and 1.6 V to 5.5 V supply tolerate harsh factory environments and 24 V loop-powered rails. The integrated LCD controller with internal voltage boost eliminates the need for a negative charge-pump circuit on mid-size panels.
Được đề xuất
Battery-Powered Consumer Electronics
The R5F10RJAAFA#V0 fits battery-powered consumer electronics such as remote controls, electronic dictionaries, and portable kitchen scales. Its 0.64 µA RTC+LVD standby current extends shelf life on coin-cell batteries, and 75 µA/MHz active consumption keeps battery-replacement intervals long. The integrated LCD controller drives reflective panels readable in low-power backlight-off mode. The 1.6 V minimum supply lets the same part run on a depleted coin cell where competitors would brown-out.

Ghi chú thiết kế
The R5F10RJAAFA#V0 has three LCD voltage generation modes: external resistor division (lowest power, requires precision resistors), capacitive split (mid-size panels, few external caps), and internal voltage boost (highest contrast, integrated charge pump with CAP0/CAP1 pins). Estimated: at 3 V VDD driving a 4-common/40-segment panel, capacitive split draws approximately 5 µA more than external resistor division. Choose the method based on panel size and contrast requirements per the RL78/L12 datasheet.
Place the 0.1 µF VDD decoupling capacitor within 3 mm of the VDD pin (pin 51) with a wide ground trace to VSS (pin 15). Keep the CAP0/CAP1 charge-pump traces short and symmetric to avoid LCD-segment mismatch. Route the TOOL0 pin (pin 52) to a 2.54 mm test pad or 4-pin header for in-circuit programming/debugging via the Renesas E1/E2 emulator.
Do not exceed 5.5 V on VDD - the internal voltage boost for LCD can reach 6 V on VL3, which the charge pump tolerates but the MCU core does not. When migrating from R5F100LEAFx (RL78/L1A) parts, note that the R5F10RJAAFA#V0 has a different pinout even though both are 52-LQFP; use the official RL78/L12 pin map, not the L1A pin map, to avoid segment-line misrouting that silently breaks the LCD panel.
