Overview
R5F10Y17DSP#30 from Renesas Electronics is a 10-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, 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 smart sensors and battery-powered HMI interfaces.
For engineers reviewing the R5F10Y17DSP#30 datasheet, R5F10Y17DSP#30 pinout, R5F10Y17DSP#30 application, or R5F10Y17DSP#30 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts with documented functional and application-level differences - all grounded in Renesas' R01DS0207EJ0321 Rev.3.21 specification.
Technical Context
The R5F10Y17DSP#30 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 watchdog timer source.
Peripheral integration targets compact control: 4-channel 10-bit ADC (3.4 µs conversion), 2-channel 16-bit timer array (TAU0) with PWM output capability, 1-channel UART (7-/8-bit), 1-channel simplified I²C master, and 1-channel simplified SPI (CSI00), all mapped to its 10-pin LSSOP package with shared analog/digital/communication pins via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y17DSP#30?
The R5F10Y17DSP#30 features a high-speed on-chip oscillator rated for 20 MHz with ±2% accuracy across –20°C to +85°C and 2.0–5.5 V supply. This specification is confirmed in Section 2.2.2 of the R01DS0207EJ0321 datasheet and eliminates the need for an external crystal in most non-precision timing applications. The R5F10Y17DSP#30 supports pre-configured frequencies including 20, 10, 5, 2.5, and 1.25 MHz via option byte settings.
Does R5F10Y17DSP#30 support hardware debugging, and what interface is used?
Yes, the R5F10Y17DSP#30 includes a 1-wire on-chip debug function using the TOOL0 pin (shared with P40). This interface enables full in-circuit debugging, flash programming, and real-time trace without requiring a dedicated JTAG/SWD connector. As stated in Section 1.1 of the datasheet, the debug function is intended for development only and must not be used in mass-produced end products due to flash endurance limitations.
How many analog input channels does R5F10Y17DSP#30 provide, and what is their resolution?
The R5F10Y17DSP#30 integrates a 10-bit successive approximation ADC with 4 analog input channels (ANI0–ANI3), as confirmed in Sections 1.1 and 1.6 of the datasheet. Conversion time is 3.4 µs, and the ADC supports an internal 2.4 V reference or external reference input. All four channels are accessible on the 10-pin LSSOP package, with ANI0–ANI3 mapped to P01–P04 pins respectively.
What are the power supply requirements and low-power modes supported by R5F10Y17DSP#30?
The R5F10Y17DSP#30 operates from a single 2.0–5.5 V supply and supports three primary low-power states: HALT (350–820 µA), STOP (0.56–2.00 µA with RAM retention), and ultra-low STOP with watchdog timer disabled. Section 2.3.2 confirms these values at 3.0 V and –40°C to +85°C. The device also includes a selectable power-on reset (SPOR) circuit with four voltage thresholds to ensure reliable startup under varying supply conditions.
Can R5F10Y17DSP#30 drive LEDs or small actuators directly, and what is the I/O current rating?
Yes, the R5F10Y17DSP#30 supports direct drive of LEDs and small actuators: each I/O pin delivers up to 20 mA sink current (IOL1) and –10 mA source current (IOH1) at 4.0–5.5 V, with total package limits of 100 mA for P00–P07. These ratings are specified in Section 2.3.1 of the datasheet. Pins P00, P01, P06, and P07 operate in N-ch open-drain mode only and cannot source high-level output.
