Product details
Overview
R5F10Y17DSP#50 from Renesas Electronics is a 16-pin, 4 KB Flash, 512-byte RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power industrial sensor nodes and battery-powered control modules. It operates from 2.0 to 5.5 V, delivers 46 µA/MHz active current, supports 7-channel 10-bit ADC with 3.4 µs conversion, and integrates UART, two CSI (SPI-compatible) channels, I²C, and four 16-bit timer channels.
For engineers reviewing the R5F10Y17DSP#50 datasheet, R5F10Y17DSP#50 pinout, R5F10Y17DSP#50 application, or R5F10Y17DSP#50 equivalent, key selection criteria include its 16-pin SSOP package, industrial-grade -40°C to +85°C operation, integrated comparator and internal reference voltage (IVREF0), and verified compatibility with Renesas' E1/E20 debug interfaces.
Technical Context
The R5F10Y17DSP#50 implements the RL78-S1 core-a Harvard-architecture CISC CPU with 3-stage pipeline, executing 78% of instructions in 1–2 clock cycles. Its timing subsystem includes a high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy at -20°C to +85°C), low-speed 15 kHz oscillator, and optional external crystal (X1/X2) or EXCLK input up to 20 MHz.
Peripheral integration targets cost-sensitive industrial control: four TAU0 timer channels support PWM output (3 channels configurable), one 12-bit interval timer (16-pin only), one analog comparator (IVCMP0/VCOUT0/IVREF0), and SAU0 serial array unit supporting UART, I²C, and dual CSI (SPI-like) interfaces-all accessible via flexible peripheral I/O redirection (PIOR).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10Y47DSP#50 | Same 16-pin SSOP package, identical 4 KB Flash/512-byte RAM, full peripheral set-including I²C, dual CSI, comparator, and 12-bit interval timer. | No functional difference; identical specification sheet (R01DS0207EJ0321) confirms R5F10Y47DSP#50 and R5F10Y17DSP#50 share identical silicon and feature mapping. | Select R5F10Y47DSP#50 only if distributor stock or lead time favors that ordering variant; no design change required. |
| RL78/G13 R5F10RGLEFP#V0 | 100-pin LQFP, 128 KB Flash, 12 KB RAM, enhanced peripherals (USB, CAN, more timers), higher current drive (50 mA/pin), but 120 µA/MHz active current. | Targeted at complex HMI or gateway applications-not suitable for space/power-constrained nodes where R5F10Y17DSP#50 excels. | Choose only when scaling beyond 4 KB code size or requiring USB/CAN; not a drop-in replacement due to package, pin count, and power profile mismatch. |
Compared with R5F10Y47DSP#50, the R5F10Y17DSP#50 offers identical functionality in the same package-making it a direct variant rather than an alternative-while the RL78/G13 introduces significant overhead in size, power, and cost unsuited for the ultra-low-power, minimal-BOM use cases R5F10Y17DSP#50 addresses.

FAQ
What is the maximum operating frequency of the R5F10Y17DSP#50?
The R5F10Y17DSP#50 supports a maximum high-speed on-chip oscillator frequency of 20 MHz (±2% accuracy from -20°C to +85°C) and accepts external system clocks up to 20 MHz via X1/X2 or EXCLK. At 20 MHz, its minimum instruction execution time is 0.05 µs, enabling responsive real-time control in the R5F10Y17DSP#50.
Does the R5F10Y17DSP#50 include an internal voltage reference for the ADC?
Yes, the R5F10Y17DSP#50 provides an internal reference voltage (IVREF0) on pin P04, specified at 0.815 V (typical). This reference is used by the 10-bit ADC to enable ratiometric measurements independent of VDD variations-confirmed in the RL78/G10 datasheet section 1.1 Features and Table 1-3 for 16-pin products.
Can the R5F10Y17DSP#50 drive standard LEDs directly from its GPIO pins?
Yes, the R5F10Y17DSP#50 GPIO pins support up to 20 mA sink current per pin (IOL1 = 20 mA) and 10 mA source current (IOH1 = -10 mA) under 4.0–5.5 V VDD conditions. This allows direct driving of standard 2–20 mA LEDs without external transistors-verified in Electrical Characteristics section 2.3.1 of the R5F10Y17DSP#50 datasheet.
Is the R5F10Y17DSP#50 compatible with Renesas' E1 or E20 debug emulators?
Yes, the R5F10Y17DSP#50 supports Renesas' E1 and E20 on-chip debug emulators via the TOOL0 pin (P40) and SWD interface. The 1-wire on-chip debug function is explicitly listed in the RL78/G10 features table and confirmed in section 1.1 of the R5F10Y17DSP#50 datasheet-enabling full breakpoint, watchpoint, and flash programming capabilities.
What is the STOP mode current consumption of the R5F10Y17DSP#50 at 3.0 V?
The R5F10Y17DSP#50 consumes 0.61 µA (typical) in STOP mode with RAM retained at VDD = 3.0 V, as specified in Electrical Characteristics section 2.3.2(2) of the official datasheet (R01DS0207EJ0321 Rev.3.21). This ultra-low quiescent current makes the R5F10Y17DSP#50 ideal for battery-operated devices requiring infrequent wake-ups.
