Product details
Overview
R5F10Y17ASP#50 from Renesas Electronics is a 10-pin, 4 KB Flash, 512-byte RAM RL78/G10 microcontroller featuring the ultra-low-power RL78-S1 core, 20 MHz high-speed on-chip oscillator (±2% accuracy), 46 µA/MHz active current, and integrated 4-channel 10-bit ADC - deployed in battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F10Y17ASP#50 datasheet, R5F10Y17ASP#50 pinout, R5F10Y17ASP#50 application, or R5F10Y17ASP#50 equivalent, key selection criteria include its LSSOP-10 package, 2.0–5.5 V operation, STOP-mode current of 0.61 µA at 3.0 V, 1-wire on-chip debug interface, and support for I²C master, UART, and simplified SPI interfaces.
Technical Context
The R5F10Y17ASP#50 implements the RL78-S1 CISC core with 3-stage Harvard pipeline, enabling 78% of instructions to execute in 1–2 clock cycles; it supports 8×8 multiply (2-cycle) and 16-bit barrel shift (2-cycle), with memory-mapped peripheral registers accessed via dedicated address space.
Its timing architecture integrates dual oscillators: a 15 kHz low-speed on-chip oscillator for watchdog and interval timer, and a programmable high-speed on-chip oscillator (1.25–20 MHz) with pre-configured settings (1.25/2.5/5/10/20 MHz); clock switching is software-controlled without external components.

FAQ
What is the maximum operating frequency of the R5F10Y17ASP#50?
The R5F10Y17ASP#50 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy across –20 to +85°C and 2.0–5.5 V supply. It also accepts external system clocks up to 20 MHz (at VDD ≥ 2.7 V) or 5 MHz (at VDD ≥ 2.0 V). The minimum instruction execution time is 0.05 µs at 20 MHz, enabling real-time response in time-critical control loops.
Does the R5F10Y17ASP#50 support hardware debugging?
Yes, the R5F10Y17ASP#50 includes a 1-wire on-chip debug function using the TOOL0 pin (P40). This allows full firmware download, breakpoint setting, register inspection, and memory access without external debug probes - ideal for rapid prototyping and field firmware updates. Note that debug usage impacts flash endurance and is not recommended for mass-production units per Renesas guidelines.
What analog peripherals are integrated into the R5F10Y17ASP#50?
The R5F10Y17ASP#50 integrates a 4-channel, 10-bit successive-approximation ADC with 3.4 µs conversion time and support for 2.4 V reference input. It does not include an on-chip comparator or internal reference voltage generator - those features are exclusive to the 16-pin RL78/G10 variants (e.g., R5F10Y47ASP#50). All four analog inputs (ANI0–ANI3) map directly to pins P01–P04.
Can the R5F10Y17ASP#50 drive LEDs or small relays directly?
Yes, the R5F10Y17ASP#50 supports up to 20 mA sink current per I/O pin (P00–P04, P40), enabling direct drive of standard LEDs and low-side relay coils without external transistors. Total sink current is limited to 100 mA across P00–P04 and 70 mA across P40/P41 (though P41 is not present in this 10-pin variant). High-side drive is not supported - all outputs are CMOS or N-ch open-drain only.
What communication interfaces does the R5F10Y17ASP#50 provide?
The R5F10Y17ASP#50 provides one UART channel (7-/8-bit), one I²C master interface (SCL00/SDA00), and one simplified SPI (CSI00) channel (SCK00/SI00/SO00). It does not support I²C multi-master, second SPI, or CAN. All three interfaces share pins with GPIO and analog functions and are reconfigurable via the Peripheral I/O Redirection Register (PIOR) for flexible PCB layout.
