Product details
Overview
R5F10Y14DSP#70 from Renesas Electronics is a 16-bit RL78/G10 microcontroller in 10-pin LSSOP package, featuring 1 KB flash, 128 B RAM, 2.0–5.5 V operation, ultra-low active current (46 µA/MHz), and integrated 20 MHz high-speed on-chip oscillator with ±2% accuracy. It serves as a cost-optimized control core in battery-powered sensor nodes and industrial status monitors.
For engineers reviewing the R5F10Y14DSP#70 datasheet, R5F10Y14DSP#70 pinout, R5F10Y14DSP#70 application, or R5F10Y14DSP#70 equivalent, key selection criteria include its 10-pin LSSOP footprint, 1 KB flash/128 B RAM configuration, support for I²C master and UART interfaces, and guaranteed -40°C to +85°C industrial temperature range.
Technical Context
The R5F10Y14DSP#70 implements the RL78-S1 core with Harvard architecture, 3-stage pipeline, and 78% of instructions executed in 1–2 clock cycles. It integrates a 10-bit ADC with 4 channels, 2-channel 16-bit timer array (TAU0), and 1-channel watchdog timer - all operating under single-supply 2.0–5.5 V conditions.
Its peripheral set includes one I²C master interface (IICA0 not present), one UART channel (RxD0/TxD0), one simplified SPI (CSI00), and key interrupt inputs (INTP0–INTP1) with 6-key return (KR0–KR5) support. The device lacks comparator, interval timer, and I²C multi-master functions - features reserved for 16-pin variants like R5F10Y44DSP#70.

FAQ
What is the maximum operating frequency of the R5F10Y14DSP#70?
The R5F10Y14DSP#70 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, delivering a minimum instruction execution time of 0.05 µs at VDD ≥ 2.7 V. External crystal or clock input (X1/EXCLK) is also supported up to 20 MHz, but the R5F10Y14DSP#70 does not include X1/X2 pins - those are only available on 16-pin variants. The R5F10Y14DSP#70 relies solely on its internal oscillator or external clock injected into P122/EXCLK.
Does the R5F10Y14DSP#70 support I²C multi-master operation?
No, the R5F10Y14DSP#70 supports only I²C master mode (IICA0 not implemented). Multi-master I²C is explicitly limited to 16-pin RL78/G10 devices such as R5F10Y44DSP#70 per Section 1.1 Features and Table 1-3. The R5F10Y14DSP#70 provides one I²C master interface (IIC00) compatible with standard slave peripherals like EEPROMs and temperature sensors.
What is the ADC reference voltage configuration for the R5F10Y14DSP#70?
The R5F10Y14DSP#70 uses VDD as its sole ADC reference voltage; it does not include the internal 0.815 V reference or comparator (IVREF0/IVCMP0) found in 16-pin variants. All 4 ADC channels (ANI0–ANI3) operate ratiometrically against VDD, making measurement accuracy dependent on supply stability. This is confirmed in Section 1.1 Features and Table 1-6, which states internal reference voltage is "only for 16-pin product".
Can the R5F10Y14DSP#70 generate PWM signals?
Yes, the R5F10Y14DSP#70 supports hardware PWM via its 2-channel 16-bit timer array (TAU0). Pins P03/TO00 and P04/TI01–TO01 can be configured as timer outputs to generate precise PWM waveforms with programmable period and duty cycle. The R5F10Y14DSP#70 does not support complementary PWM or dead-time insertion - features reserved for higher-pin-count variants.
Is the R5F10Y14DSP#70 pin-compatible with other RL78/G10 10-pin devices?
Yes, the R5F10Y14DSP#70 shares identical 10-pin LSSOP pinout and electrical characteristics with all other 10-pin RL78/G10 devices (e.g., R5F10Y16DSP#70, R5F10Y17DSP#70). Differences are limited to flash/RAM size and factory-programmed option bytes; no PCB redesign is needed when upgrading within the 10-pin family. Pin mapping is fully defined in Table 1-2 and Figure 1-1.
