Product details
Overview
R5F10Y14ASP#V0 from Renesas Electronics is a 10-pin, 1 KB Flash, 128-byte RAM RL78/G10 16-bit microcontroller with ultra-low-power operation (46 µA/MHz), 2.0–5.5 V supply range, and integrated 20 MHz high-speed on-chip oscillator. It features 4-channel 10-bit ADC, 1× UART, 1× simplified I²C, 1× simplified SPI, 2-channel 16-bit timer array, and key interrupt support - deployed in battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F10Y14ASP#V0 datasheet, R5F10Y14ASP#V0 pinout, R5F10Y14ASP#V0 application, or R5F10Y14ASP#V0 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts for cost, power, or feature trade-offs in compact embedded designs.
Technical Context
The R5F10Y14ASP#V0 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, enabling 78% of instructions to execute in 1–2 clock cycles. Its low-power design includes STOP mode (0.56 µA) and HALT mode (350–820 µA), supported by selectable power-on reset (SPOR) with four voltage thresholds and 15 kHz watchdog timer.
Peripherals are tightly coupled to the 10-pin LSSOP package: all 6 GPIOs support analog input (ANI0–ANI3), key return (KR0–KR5), and timer I/O (TI00/TO00, TI01/TO01); communication is limited to UART0, CSI00 (simplified SPI), and IIC00 (simplified I²C) - no I²C multi-master or interval timer, which are exclusive to 16-pin variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10Y16ASP#V0 | 2 KB Flash, 256 B RAM, same 10-pin LSSOP package, identical peripheral set | Supports larger firmware (e.g., BLE stack integration or enhanced UI logic) without layout change | Select when firmware size exceeds 1 KB or future scalability is required; same pinout and power profile |
| R5F10Y44ASP#V0 | 16-pin SSOP, adds 3 extra ADC channels (7 total), interval timer, I²C multi-master, second CSI channel | Enables multi-sensor fusion (e.g., temp + pressure + humidity) and dual-interface communication (UART + I²C slave) | Choose when additional analog inputs, precise periodic wake-up (interval timer), or I²C slave connectivity are mandatory |
Compared with R5F10Y14ASP#V0, R5F10Y16ASP#V0 offers direct firmware headroom within identical power and footprint constraints, while R5F10Y44ASP#V0 trades compactness for expanded analog and communication capability - making it suitable only when the 10-pin limitation is insufficient for signal acquisition or interface requirements.

FAQ
What is the maximum operating frequency of the R5F10Y14ASP#V0?
The R5F10Y14ASP#V0 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, yielding a minimum instruction execution time of 0.05 µs at VDD ≥ 2.7 V. External crystal or clock input (X1/EXCLK) also supports up to 20 MHz, but only within the 2.7–5.5 V supply range; below 2.7 V, max external clock is 5 MHz. The R5F10Y14ASP#V0 does not include an internal PLL, so system clock equals oscillator frequency.
Does the R5F10Y14ASP#V0 support I²C multi-master operation?
No, the R5F10Y14ASP#V0 does not support I²C multi-master operation. Its IIC00 peripheral is configured as a simplified I²C master-only interface, as confirmed in Section 1.1 Features and Table 1-2 of the datasheet. Multi-master capability is explicitly reserved for 16-pin RL78/G10 variants (e.g., R5F10Y44ASP#V0) and is absent from all 10-pin products including the R5F10Y14ASP#V0.
What ADC reference voltage options are available on the R5F10Y14ASP#V0?
The R5F10Y14ASP#V0 supports only the internal 1.45 V bandgap reference (VREF) and external VDD as ADC reference sources. It does not include the 0.815 V internal reference voltage (IVREF0) or comparator reference input (IVREF0), both of which are exclusive to 16-pin RL78/G10 devices per Section 1.1 and Table 1-3. The R5F10Y14ASP#V0's 4-channel 10-bit ADC operates with 3.4 µs conversion time and supports analog inputs up to 2.4 V.
Can the R5F10Y14ASP#V0 generate PWM signals?
Yes, the R5F10Y14ASP#V0 can generate PWM signals using its 2-channel 16-bit timer array (TAU0). TO00 and TO01 outputs support PWM waveform generation with configurable duty cycle and period. However, it lacks the 12-bit interval timer and advanced PWM features (e.g., complementary outputs or dead-time insertion) found in 16-pin variants. The R5F10Y14ASP#V0's PWM capability is sufficient for LED dimming, basic motor control, or buzzer tone generation via PCLBUZ0.
Is the R5F10Y14ASP#V0 qualified for industrial temperature range?
Yes, the R5F10Y14ASP#V0 is rated for industrial operating ambient temperature of –40°C to +85°C, as specified in Section 1.1 and confirmed by the "A" suffix in its part number (R5F10Y14ASP#V0), denoting consumer/industrial grade qualification. This rating applies across its full 2.0–5.5 V supply range and all specified operating modes (active, HALT, STOP), making it suitable for deployment in uncontrolled environments such as factory floors or outdoor enclosures.
