Product details
Overview
R5F10Y16DSP#10 from Renesas Electronics is a 10-pin, 2 KB Flash, 256-byte RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power embedded control. It operates from 2.0 to 5.5 V, achieves 46 µA/MHz active current and 0.56 µA STOP mode, and integrates a 20 MHz ±2% on-chip oscillator, 4-channel 10-bit ADC, UART, I²C, and simplified SPI - deployed in battery-powered sensor nodes and industrial status monitors.
For engineers reviewing the R5F10Y16DSP#10 datasheet, R5F10Y16DSP#10 pinout, R5F10Y16DSP#10 application, or R5F10Y16DSP#10 equivalent, key selection criteria include its 10-pin LSSOP package, verified 2 KB Flash/256 B RAM configuration, industrial-grade −40°C to +85°C operation, and confirmed support for key interrupt (KR0–KR5), timer I/O (TI00/TO00, TI01/TO01), and analog input (ANI0–ANI3) functions per Renesas R01DS0207EJ0321 Rev.3.21.
Technical Context
The R5F10Y16DSP#10 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, enabling 78% of instructions in 1–2 clock cycles. Its power management includes selectable power-on reset (SPOR) with four voltage thresholds and dual oscillators: high-speed on-chip (1.25–20 MHz) and low-speed (15 kHz).
Peripheral integration centers on a 2-channel 16-bit timer array unit (TAU0), 1-channel UART (7-/8-bit), 1-channel simplified I²C (IIC00), 1-channel simplified SPI (CSI00), and 4-channel 10-bit ADC with 3.4 µs conversion time - all mapped exclusively to its 10-pin LSSOP footprint without shared or conditional functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78-S1 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained systems. |

Pinout & Package
Package: 10-pin plastic LSSOP (4.4 × 3.6 mm, 0.65 mm pitch), industrial-grade (D-suffix), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P40 | RESET / KR0 / TOOL0 | Primary reset input; also serves as Key Return 0 and debug interface pin - requires external pull-up for reliable reset assertion. |
| P125 | RESET / KR1 | Dedicated reset pin with internal pull-down; KR1 enables matrix keypad scanning without external diodes. |
| P137 | INTP0 / TI00 | External interrupt source and timer input channel 0; supports edge-triggered wake-up from STOP mode. |
| VSS | Ground | System reference ground; must be connected directly to PCB ground plane for noise immunity. |

The R5F10Y16DSP#10 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, with ±2% accuracy over −20°C to +85°C and full 2.0–5.5 V operation. External crystal or clock input up to 20 MHz is also supported, but the R5F10Y16DSP#10's internal oscillator eliminates external components for most timing-critical applications like UART communication.
Does the R5F10Y16DSP#10 support analog-to-digital conversion?
Yes, the R5F10Y16DSP#10 integrates a 10-bit resolution ADC with 4 input channels (ANI0–ANI3). Conversion time is 3.4 µs, and it supports reference voltages down to 2.4 V. This ADC is fully functional in the 10-pin LSSOP package and is commonly used for temperature sensing, battery voltage monitoring, and analog sensor interfacing in the R5F10Y16DSP#10 design.
What debug interface does the R5F10Y16DSP#10 provide?
The R5F10Y16DSP#10 features a 1-wire on-chip debug function accessible via the TOOL0 pin (P40). This allows full program download, breakpoint setting, and real-time variable inspection using Renesas E2 studio and compatible debug probes - all with minimal pin count impact, which is essential for space-constrained 10-pin designs.
Is the R5F10Y16DSP#10 suitable for industrial temperature ranges?
Yes, the R5F10Y16DSP#10 is rated for operation from −40°C to +85°C and carries the 'D' suffix indicating industrial qualification. Its electrical specifications - including oscillator accuracy, supply current, and I/O drive strength - are guaranteed across this full range, making it appropriate for deployment in factory automation, building controls, and outdoor sensor enclosures.
How many key interrupt (KR) inputs does the R5F10Y16DSP#10 support?
The R5F10Y16DSP#10 supports six dedicated key return inputs (KR0 through KR5), mapped to pins P40, P125, P137, P01, P02, and P03. These inputs include hardware debounce and can wake the device from STOP mode, enabling efficient matrix keypad interfaces without external logic or continuous CPU polling - a core capability confirmed for the R5F10Y16DSP#10 in Renesas documentation.
