Product details
Overview
R5F10Y47DSP#10 from Renesas Electronics is a 16-pin, 4 KB Flash, 512-byte RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power embedded control in industrial and consumer applications. It operates from 2.0 to 5.5 V, delivers 46 µA/MHz active current, integrates a 20 MHz ±2% on-chip oscillator, 7-channel 10-bit ADC, and supports UART, I²C, and dual CSI (SPI-compatible) interfaces - deployed in battery-powered sensor nodes and smart home controllers.
For engineers reviewing the R5F10Y47DSP#10 datasheet, R5F10Y47DSP#10 pinout, R5F10Y47DSP#10 application, or R5F10Y47DSP#10 equivalent, key selection criteria include its 16-pin SSOP package, industrial-grade −40°C to +85°C operation, integrated key interrupt (KR0–KR5), programmable buzzer/clock output (PCLBUZ0), and verified compatibility with Renesas' E2 emulator and CS+ IDE toolchain.
Technical Context
The R5F10Y47DSP#10 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute in 1–2 clock cycles. Its timing subsystem includes a high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy over voltage/temperature), low-speed 15 kHz watchdog timer, and optional external crystal (X1/X2) or EXCLK input up to 20 MHz.
Peripheral integration centers on a 4-channel TAU0 timer array (with PWM outputs on TO00–TO03), SAU0 serial array unit supporting UART, I²C, and two CSI channels, and a 7-channel 10-bit ADC with 3.4 µs conversion time and internal reference (IVREF0). Safety features include illegal instruction detection and selectable power-on reset (SPOR) with four voltage thresholds.
Key Specifications

Pinout & Package
Package: 16-pin plastic SSOP (4.4 × 5.0 mm, 0.65 mm pitch), industrial-grade (D-suffix), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | Port 0 bit 0 / UART TX / INT | Primary serial transmit line; doubles as external interrupt input (INTP1) for wake-up from STOP mode. |
| P01 | Port 0 bit 1 / UART RX / ADC0 / I²C SDA | Serial receive with hardware flow control; shares pin with analog input ANI0 and I²C data - enables shared bus architecture with minimal PCB routing. |

FAQ
What is the maximum operating frequency of the R5F10Y47DSP#10?
The R5F10Y47DSP#10 supports a maximum system clock frequency of 20 MHz using either the high-speed on-chip oscillator or an external crystal/resonator. At 20 MHz, its minimum instruction execution time is 0.05 µs (VDD ≥ 2.7 V), enabling responsive real-time control in motor drivers and sensor fusion algorithms. The on-chip oscillator maintains ±2% accuracy across −20°C to +85°C.
Does the R5F10Y47DSP#10 support hardware debugging?
Yes, the R5F10Y47DSP#10 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40). This enables full flash programming, breakpoint setting, and real-time variable inspection using Renesas' E2 or E2 Lite debug emulators and CS+ IDE. Debug access requires no additional pins beyond the standard SWD/JTAG footprint.
Can the R5F10Y47DSP#10 drive LEDs directly without external transistors?
Yes, the R5F10Y47DSP#10 can drive standard LEDs directly: its I/O pins support up to 20 mA sink current per pin (IOL1) and 10 mA source current (IOH1) at VDD = 5.0 V. For common-anode configurations, connect LED cathode to P00–P07 and anode to VDD through a current-limiting resistor - verified in Renesas' RL78/G10 hardware design guidelines.
What analog reference options are available for the ADC in the R5F10Y47DSP#10?
The R5F10Y47DSP#10 ADC supports three reference sources: external VDD, external VSS, or internal 0.815 V reference (IVREF0) - selectable via the ADSCR register. IVREF0 is factory-trimmed and stable across temperature, enabling ratiometric measurements independent of supply variation. This internal reference is only available on 16-pin variants like the R5F10Y47DSP#10.
Is the R5F10Y47DSP#10 pin-compatible with other RL78/G10 16-pin variants?
Yes, the R5F10Y47DSP#10 shares identical pinout, package (16-pin SSOP), and peripheral mapping with all RL78/G10 16-pin members including R5F10Y44DSP#10 and R5F10Y46DSP#10. Firmware and PCB layouts are interchangeable across these variants - only Flash/RAM capacity and SPOR voltage settings differ, controlled by option bytes during programming.
