Product details
Overview
R5F10Y17ASP#70 from Renesas Electronics is a 16-pin, 4 KB Flash, 512-byte RAM RL78/G10 16-bit microcontroller with ultra-low-power operation (46 µA/MHz), 2.0–5.5 V supply range, and integrated 20 MHz ±2% high-speed on-chip oscillator. It features 7-channel 10-bit ADC, 4-channel 16-bit timer array, UART, I²C, two CSI interfaces, and key interrupt support - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y17ASP#70 datasheet, R5F10Y17ASP#70 pinout, R5F10Y17ASP#70 application, or R5F10Y17ASP#70 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts for design flexibility and supply continuity.
Technical Context
The R5F10Y17ASP#70 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute in 1–2 clock cycles. It supports 8×8 multiply (2-cycle) and 16-bit barrel shift (2-cycle), enabling efficient signal conditioning and timing-critical control loops.
Its peripheral set is fully enabled for 16-pin SSOP variants: dual CSI (Simplified SPI), full I²C master, UART, 7-channel ADC with internal 0.815 V reference, comparator with IVREF0/IVCMP0/VCOUT0 pins, and 4-channel TAU0 with PWM capability - all operating under single-supply 2.0–5.5 V conditions.

FAQ
What is the maximum operating frequency of the R5F10Y17ASP#70?
The R5F10Y17ASP#70 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy over –20 to +85°C. When using an external crystal or clock source, the maximum system clock frequency remains 20 MHz, with minimum instruction execution time of 0.05 µs under 2.7–5.5 V supply conditions. The R5F10Y17ASP#70 does not support frequencies above 20 MHz.
Does the R5F10Y17ASP#70 include an internal voltage reference for the ADC?
Yes, the R5F10Y17ASP#70 includes an internal 0.815 V (typ.) reference voltage (IVREF0) specifically for the 10-bit ADC - accessible on pin P04. This reference enables ratiometric measurements independent of VDD fluctuations and eliminates the need for external precision references in sensor applications. The R5F10Y17ASP#70 datasheet confirms IVREF0 is available only on 16-pin variants like this part.
Can the R5F10Y17ASP#70 drive a buzzer directly?
Yes, the R5F10Y17ASP#70 supports direct buzzer drive via the PCLBUZ0 function on pins P02 and P40. It delivers programmable clock outputs from 2.44 kHz to 10 MHz (at fMAIN = 20 MHz), with up to 20 mA sink/source per GPIO. The R5F10Y17ASP#70's IOL specification (20 mA per pin, 120 mA total) ensures reliable operation with common electromagnetic and piezoelectric buzzers without external drivers.
Is the R5F10Y17ASP#70 pin-compatible with other RL78/G10 16-pin variants?
Yes, the R5F10Y17ASP#70 shares identical pinout, package (16-pin SSOP), and peripheral mapping with all RL78/G10 16-pin parts including R5F10Y44ASP#70 and R5F10Y46ASP#70. All share the same pin functions (e.g., P00 = TxD0, P04 = IVREF0), register layout, and memory map - enabling hardware reuse across Flash size variants. Firmware compiled for R5F10Y17ASP#70 runs unchanged on R5F10Y46ASP#70 if within its 2 KB Flash limit.
What debug interface does the R5F10Y17ASP#70 support?
The R5F10Y17ASP#70 supports 1-wire on-chip debugging via the TOOL0 function on pin P40, compliant with Renesas E1/E20 emulators. This interface enables full flash programming, real-time variable watch, and breakpoint debugging without dedicated SWD/JTAG pins. The R5F10Y17ASP#70 does not require external debug headers - TOOL0 shares the pin with KR0 and TI01/TO01, minimizing PCB footprint.
