Product details
Overview
R5F10Y44DSP#10 from Renesas Electronics is a 16-pin, 1 KB Flash, 128-byte RAM RL78/G10 microcontroller featuring the RL78-S1 core, 2.0–5.5 V operation, 46 µA/MHz active current, and integrated 10-bit ADC with 7 channels. It supports UART, two CSI (Simplified SPI) interfaces, I²C, four 16-bit timer channels, and key interrupt functionality - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y44DSP#10 datasheet, R5F10Y44DSP#10 pinout, R5F10Y44DSP#10 application, or R5F10Y44DSP#10 equivalent, this page delivers verified electrical specs, package mapping to 16-pin SSOP, confirmed peripheral allocation (e.g., P04 = ANI3/TI01/TO01/KR5/IVREF0), and real-world selection guidance against functionally aligned alternatives.
Technical Context
The R5F10Y44DSP#10 implements the RL78-S1 CISC core with 3-stage pipeline and Harvard architecture, enabling 78% of instructions in 1–2 clock cycles. Its clock system combines a high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy at −20 to +85°C) and low-speed 15 kHz oscillator for ultra-low-power STOP mode (0.61 µA @ 3.0 V).
Peripheral integration includes a 7-channel 10-bit ADC (3.4 µs conversion time, reference voltage IVREF0 on P04), one comparator (IVCMP0 on P03, VCOUT0 on P11), and four 16-bit timer array unit (TAU0) channels supporting PWM output - all accessible via fixed pin assignments per the 16-pin SSOP layout and validated by Renesas' R01DS0207EJ0321 Rev.3.21 datasheet.

The R5F10Y44DSP#10 supports a maximum high-speed on-chip oscillator frequency of 20 MHz (±2% accuracy from −20°C to +85°C). When using an external crystal (X1/X2) or clock input (EXCLK), it operates 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 under 20 MHz operation, as specified in the R01DS0207EJ0321 Rev.3.21 datasheet.
Does the R5F10Y44DSP#10 include an internal ADC, and what are its capabilities?
Yes, the R5F10Y44DSP#10 integrates a 10-bit successive approximation register (SAR) ADC with 7 input channels (ANI0–ANI6). It achieves 3.4 µs conversion time, supports internal reference voltage (IVREF0 on P04), and operates across the full 2.0–5.5 V supply range. The ADC is validated for use in precision analog sensing applications such as temperature monitoring and power supply voltage measurement, per Section 1.6 and Table 2.3.2 of the official datasheet.
What package type and pin count does the R5F10Y44DSP#10 use?
The R5F10Y44DSP#10 uses a 16-pin plastic SSOP package (PRSP0016JC-B), measuring 4.4 × 5.0 mm with 0.65 mm lead pitch. This industrial-grade package supports −40°C to +85°C operation and is explicitly listed in Table 1-1 of the R01DS0207EJ0321 datasheet for the "16-pin products" row under ordering part number R5F10Y44DSP.
Can the R5F10Y44DSP#10 operate from a 2.0 V supply, and what features remain functional?
Yes, the R5F10Y44DSP#10 is fully specified for 2.0–5.5 V operation. At 2.0 V, the high-speed on-chip oscillator runs up to 5 MHz, the ADC remains operational (with adjusted timing), and all I/O ports retain 20 mA sink capability. STOP mode current increases to 2.25 µA max, and external clock input is limited to 1–5 MHz - all confirmed in Sections 2.2.2 and 2.3.2 of the R01DS0207EJ0321 datasheet.
What debug interface does the R5F10Y44DSP#10 support, and how is it implemented?
The R5F10Y44DSP#10 supports a 1-wire on-chip debug interface routed to the TOOL0 pin (P40), enabling full firmware download, breakpoint setting, and real-time variable inspection without external debug probes. This interface is documented in Section 1.1 and Figure 1-5 of the R01DS0207EJ0321 datasheet and requires no additional hardware beyond a single signal trace and pull-up resistor.
