Product details
Overview
R5F10Y44ASP#70 from Renesas Electronics is a 16-pin, 4 KB Flash, 512-byte RAM RL78/G10 microcontroller with RL78-S1 core, operating at 2.0–5.5 V and delivering ultra-low power consumption (46 µA/MHz active, 0.61 µA STOP mode). It integrates 7-channel 10-bit ADC, 4-channel 16-bit timer array, UART, dual CSI (SPI-compatible), I²C, and key interrupt support - deployed in battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F10Y44ASP#70 datasheet, R5F10Y44ASP#70 pinout, R5F10Y44ASP#70 application, or R5F10Y44ASP#70 equivalent, this page delivers verified package mapping (16-pin SSOP), confirmed peripheral allocation (e.g., P04 = ANI3/TI01/TO01/KR5/IVREF0), real-world supply current values across HALT/STOP modes, and two validated alternative parts for cost- or feature-sensitive designs.
Technical Context
The R5F10Y44ASP#70 implements the RL78-S1 CISC core with 3-stage pipeline and Harvard architecture, enabling 78% of instructions in 1–2 clock cycles. Its high-speed on-chip oscillator delivers 20 MHz ±2% accuracy over –40°C to +85°C and full voltage range (2.0–5.5 V), eliminating external crystal dependency in many applications.
Peripheral integration includes a 7-channel 10-bit ADC with 3.4 µs conversion time and internal reference (IVREF0), one comparator (IVCMP0/VCOUT0), and four independent 16-bit timer channels supporting PWM output - all accessible via dedicated pins (e.g., TO00–TO03) without multiplexing conflict in default PIOR=00H configuration.

FAQ
What is the maximum operating frequency and voltage range for the R5F10Y44ASP#70?
The R5F10Y44ASP#70 operates at up to 20 MHz using its high-speed on-chip oscillator, with guaranteed operation across 2.0 V to 5.5 V supply voltage. At 2.0–2.7 V, max clock is limited to 5 MHz; above 2.7 V, full 20 MHz is supported. This wide voltage range enables direct use with single-cell Li-ion, 3×AA, or regulated 3.3 V/5 V rails without level-shifting.
Does the R5F10Y44ASP#70 include an internal voltage reference for the ADC?
Yes, the R5F10Y44ASP#70 provides an internal 0.815 V (typical) reference voltage accessible via the IVREF0 function on pin P04. This reference is used by the 10-bit ADC for conversions, eliminating the need for external precision references in most sensor applications - confirmed in Table 1-3 and Section 1.6 of the R01DS0207EJ0321 datasheet.
How many ADC channels does the R5F10Y44ASP#70 support, and what is their resolution?
The R5F10Y44ASP#70 supports seven 10-bit analog-to-digital converter channels (ANI0–ANI6), with a minimum conversion time of 3.4 µs. All channels are accessible on dedicated pins in the 16-pin SSOP package, and the ADC operates down to 2.4 V supply - enabling accurate temperature, voltage, and current sensing across the full industrial temperature range.
Can the R5F10Y44ASP#70 drive standard LEDs or small relays directly from its GPIO pins?
Yes, the R5F10Y44ASP#70 GPIO pins (P00–P07) support up to 20 mA sink/source per pin and 100 mA total for the port group. This allows direct driving of standard 5 mm LEDs (with series resistor) or small signal relays (e.g., 5 V coil, <15 mA hold current) without external drivers - verified in Section 2.3.1 DC Characteristics of the R01DS0207EJ0321 datasheet.
Is there hardware support for I²C communication on the R5F10Y44ASP#70?
Yes, the R5F10Y44ASP#70 includes a dedicated I²C interface (IICA0) with SDA00 and SCL00 pins (P01 and P02), supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation. The hardware handles arbitration, clock stretching, and ACK/NACK generation - freeing CPU cycles for application tasks, as documented in Section 1.6 and Figure 1-5 of the datasheet.
