Product details
Overview
R5F10Y14DSP#30 from Renesas Electronics is a 16-bit RL78/G10 microcontroller in 16-pin SSOP package, featuring 1 KB Flash, 128 B RAM, 2.0–5.5 V operation, ultra-low-power Stop mode (0.56 µA), and integrated 10-bit ADC with 4 channels. It targets cost-sensitive, battery-powered sensor nodes and simple control applications requiring minimal footprint and high energy efficiency.
For engineers reviewing the R5F10Y14DSP#30 datasheet, R5F10Y14DSP#30 pinout, R5F10Y14DSP#30 application, or R5F10Y14DSP#30 equivalent, this page delivers verified technical context, exact pin functions for 16-pin SSOP layout, real-world use cases in industrial sensing and HMI, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R5F10Y14DSP#30 implements the RL78-S1 core with Harvard architecture, 3-stage pipeline, and 78% of instructions executed in 1–2 clock cycles. It supports 20 MHz max operation via high-speed on-chip oscillator (±2% accuracy over –40°C to +85°C) and includes selectable power-on reset with four voltage thresholds (2.25 V to 4.45 V).
It integrates one UART (7-/8-bit), one I²C master interface, two simplified SPI (CSI) channels, four 16-bit timer channels, and a 10-bit ADC with 4 input channels and 3.4 µs conversion time. Key interrupt sources include four external inputs (INTP0–INTP3), six key return lines (KR0–KR5), and illegal instruction detection.

FAQ
What is the maximum operating frequency of the R5F10Y14DSP#30?
The R5F10Y14DSP#30 supports up to 20 MHz operation using its high-speed on-chip oscillator, with ±2% accuracy across –40°C to +85°C and 2.0–5.5 V supply. External crystal or clock input (X1/X2 or EXCLK) is optional and supports 1–20 MHz, but the on-chip oscillator eliminates BOM cost and board space for most applications. The R5F10Y14DSP#30 achieves 20 MIPS at 20 MHz with its RL78-S1 core.
Does the R5F10Y14DSP#30 support hardware debugging?
Yes, the R5F10Y14DSP#30 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40). This enables full flash programming, real-time breakpointing, and register inspection without requiring dedicated debug headers. However, Renesas advises against using the debug function in mass-produced end products due to potential flash endurance impact-production units should rely on pre-programmed firmware or bootloader-based updates.
How many analog input channels does the R5F10Y14DSP#30 have?
The R5F10Y14DSP#30 features a 10-bit successive-approximation ADC with exactly 4 analog input channels (ANI0–ANI3), mapped to P01–P04. Conversion time is 3.4 µs at maximum speed. Unlike the 16-pin R5F10Y4x variants, it does not include the internal reference voltage (IVREF0) or comparator (IVCMP0/VCOUT0), limiting its analog capability to basic sensor interfacing without on-chip reference or threshold comparison.
What are the power supply requirements for the R5F10Y14DSP#30?
The R5F10Y14DSP#30 operates from a single 2.0–5.5 V supply (VDD), with absolute maximum rating of –0.5 to +6.5 V. Its selectable power-on reset (SPOR) circuit has four rising-edge thresholds (2.25 V, 2.68 V, 3.02 V, 4.45 V), and Renesas specifies minimum operational voltage as 2.25 V to ensure SPOR reliability. For stable 20 MHz operation, VDD ≥ 2.7 V is recommended per AC characteristics.
Is the R5F10Y14DSP#30 pin-compatible with other RL78/G10 devices?
Yes-the R5F10Y14DSP#30 shares the identical 16-pin SSOP (PRSP0016JC-B) package and pinout with all other 16-pin RL78/G10 variants, including R5F10Y44DSP#30, R5F10Y46DSP#30, and R5F10Y47DSP#30. This enables drop-in replacement for memory or peripheral upgrades (e.g., moving to 2 KB Flash or adding comparator) without PCB redesign, provided firmware and configuration registers are updated accordingly.
