Product details
Overview
R5F10Y44ASP#30 from Renesas Electronics is a 16-pin RL78/G10 16-bit microcontroller with 1 KB Flash, 128 B RAM, and ultra-low-power operation (46 µA/MHz active, 0.61 µA STOP). It integrates a 20 MHz high-speed on-chip oscillator (±2% accuracy), 7-channel 10-bit ADC, 4-channel 16-bit timer array, UART, two CSI interfaces, and I²C master - deployed in battery-powered sensor nodes and smart home controllers.
For engineers reviewing the R5F10Y44ASP#30 datasheet, R5F10Y44ASP#30 pinout, R5F10Y44ASP#30 application, or R5F10Y44ASP#30 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 validated alternative options for cost- or feature-sensitive designs.
Technical Context
The R5F10Y44ASP#30 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute in 1–2 cycles. Its clock system supports dual sources: high-speed on-chip oscillator (1.25–20 MHz) and external crystal (1–20 MHz via X1/X2), with automatic fallback and oscillation stabilization monitoring via OSTC register.
Peripheral integration follows strict pin-multiplexing controlled by the Peripheral I/O Redirection Register (PIOR). All 16 pins support configurable functions - e.g., P03 serves as ANI2, TO00, KR4, or INTP1 depending on PIOR settings - enabling flexible signal routing without hardware redesign.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y44ASP#30?
The R5F10Y44ASP#30 features a high-speed on-chip oscillator with a maximum frequency of 20 MHz and ±2% accuracy over –20°C to +85°C, and ±3% over –40°C to –20°C. This oscillator is factory-trimmed and requires no external components, enabling rapid system startup and reducing BOM cost. The R5F10Y44ASP#30 supports five pre-configured frequencies (1.25/2.5/5/10/20 MHz) selected via option byte settings.
Does R5F10Y44ASP#30 support external crystal oscillation, and what are the valid frequency ranges?
Yes, the R5F10Y44ASP#30 supports external crystal or ceramic resonator operation via X1/X2 pins. Valid frequency ranges are 1–20 MHz at VDD ≥ 2.7 V, and 1–5 MHz at VDD = 2.0–2.7 V. Oscillation stabilization must be verified using the OSTC register before switching from the on-chip oscillator. The R5F10Y44ASP#30 does not include an internal crystal load capacitor - external capacitors must be selected per resonator manufacturer specifications.
How many analog input channels does R5F10Y44ASP#30 provide, and what ADC resolution and speed are supported?
The R5F10Y44ASP#30 provides seven analog input channels (ANI0–ANI6) with 10-bit resolution and a typical conversion time of 3.4 µs. It supports internal reference voltage (0.815 V) on P04 (IVREF0) for ratiometric measurements and operates down to 2.4 V supply. The ADC is fully functional in normal and HALT modes but disabled in STOP mode unless explicitly enabled via control registers.
What communication interfaces are integrated into R5F10Y44ASP#30, and are they pin-multiplexed?
The R5F10Y44ASP#30 integrates one UART channel (RxD0/TxD0), one I²C master interface (SCL00/SDA00), and two Simplified SPI (CSI) channels (CSI00 and CSI01). All interfaces are fully pin-multiplexed - for example, P01 serves as SDA00 or ANI0, and P07 serves as SDAA0 or ANI6 - with function selection controlled by the Peripheral I/O Redirection Register (PIOR). No dedicated hardware conflict exists between interfaces when configured correctly.
What is the guaranteed operating temperature range and supply voltage specification for R5F10Y44ASP#30?
The R5F10Y44ASP#30 is specified for industrial-grade operation from –40°C to +85°C ambient temperature and supports a single supply voltage range of 2.0 V to 5.5 V. The selectable power-on-reset (SPOR) circuit has four detection thresholds (2.25/2.68/3.02/4.45 V), and operation below 2.25 V is not recommended due to SPOR margin constraints. All electrical characteristics, including ADC accuracy and oscillator stability, are guaranteed across this full range.
