Product details
Overview
R5F10Y17ASP#30 from Renesas is a 10-pin, 4 KB Flash, 512-byte RAM RL78/G10 16-bit microcontroller with ultra-low-power operation (46 µA/MHz active, 0.56 µA STOP), 2.0–5.5 V supply, and integrated 20 MHz ±2% on-chip oscillator. It features 4-channel 10-bit ADC, 2× 16-bit timers, UART, I²C, simplified SPI (CSI), key interrupt support, and operates across –40°C to +85°C for battery-powered sensor nodes and smart peripherals.
For engineers reviewing the R5F10Y17ASP#30 datasheet, R5F10Y17ASP#30 pinout, R5F10Y17ASP#30 application, or R5F10Y17ASP#30 equivalent, this page delivers verified technical context, exact package mapping (10-pin LSSOP), confirmed peripheral allocation, real-world use-value metrics, and two validated alternative parts - all derived exclusively from Renesas R01DS0207EJ0321 Rev.3.21 (Mar 2024).
Technical Context
The R5F10Y17ASP#30 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute in 1–2 clock cycles. Its power management includes selectable power-on reset (SPOR) with four voltage thresholds (2.25/2.68/3.02/4.45 V), low-power HALT/STOP modes, and independent low-speed (15 kHz) and high-speed (1.25–20 MHz) on-chip oscillators.
Peripheral integration is fixed per 10-pin configuration: SAU0 provides one serial array unit supporting UART and simplified I²C/CSI; TAU0 supplies two 16-bit timer channels with TO00/TO01 outputs and TI00/TI01 inputs; ADC supports four analog inputs (ANI0–ANI3) at 3.4 µs conversion time; and six key return (KR0–KR5) pins enable direct matrix keypad interfacing without external logic.

FAQ
What is the maximum operating frequency of the R5F10Y17ASP#30?
The R5F10Y17ASP#30 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy over –20°C to +85°C. When using an external crystal or clock source, the maximum system clock frequency is also 20 MHz (at VDD ≥ 2.7 V). The minimum instruction execution time is 0.05 µs under these conditions, enabling deterministic real-time performance for time-critical tasks.
Does the R5F10Y17ASP#30 support hardware debugging?
Yes, the R5F10Y17ASP#30 includes a 1-wire on-chip debug function accessible via the P40 (TOOL0) pin. This allows full breakpoint, step-through, and memory inspection capabilities using Renesas E2 emulator or compatible tools - eliminating the need for dedicated debug headers and reducing PCB layout complexity.
How many analog input channels does the R5F10Y17ASP#30 have?
The R5F10Y17ASP#30 has four analog input channels (ANI0 through ANI3), mapped to pins P01, P02, P03, and P04 respectively. All channels support 10-bit resolution with a 3.4 µs conversion time and operate down to 2.4 V reference, making them suitable for precision sensor interfacing in low-voltage battery systems.
What are the power supply requirements for reliable operation of the R5F10Y17ASP#30?
The R5F10Y17ASP#30 requires a single 2.0–5.5 V supply on VDD, but Renesas specifies that operation must remain within 2.25–5.5 V due to the selectable power-on reset (SPOR) circuit's lowest detection threshold. Decoupling with a 0.1 µF ceramic capacitor placed ≤2 mm from VDD/VSS is mandatory to achieve the rated 0.56 µA STOP current and stable ADC performance.
Can the R5F10Y17ASP#30 drive LEDs directly without external transistors?
Yes, the R5F10Y17ASP#30 can drive standard LEDs directly: each I/O pin (P00–P04, P40) supports up to 20 mA sink current (low-level output), sufficient for common 2–20 mA indicator LEDs. However, the total sink current across all pins must not exceed 100 mA, and high-side (source) drive capability is limited - so cathode-connected LED configurations are recommended.
