Product details
Overview
R5F10Y47ASP#50 from Renesas Electronics is a 16-pin, 4 KB Flash, 512 B 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, two CSI interfaces, I²C, comparator, and key interrupt support - deployed in battery-powered sensor nodes and industrial control modules.
For engineers reviewing the R5F10Y47ASP#50 datasheet, R5F10Y47ASP#50 pinout, R5F10Y47ASP#50 application, or R5F10Y47ASP#50 equivalent, this page delivers verified technical context, package-accurate pin mapping, real-world use cases, and validated alternative options for low-voltage embedded designs requiring sub-1 µA STOP mode current and mixed-signal integration.
Technical Context
The R5F10Y47ASP#50 implements the RL78-S1 core - a Harvard-architecture CISC CPU with 3-stage pipeline, executing 78% of instructions in 1–2 clock cycles. It supports 8×8 multiply (2-cycle) and 16-bit barrel shift (2-cycle), enabling efficient firmware math and bit manipulation in resource-constrained systems.
Its timing architecture integrates dual oscillators: a 20 MHz ±2% high-speed on-chip oscillator (operable down to 2.0 V) and a 15 kHz low-speed oscillator, plus optional external crystal (X1/X2) or EXCLK input up to 20 MHz. The 12-bit interval timer and watchdog timer operate independently of main clock domains for robust timekeeping and fault recovery.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10Y46ASP#50 | 2 KB Flash, 256 B RAM, identical pinout and peripherals - lacks 3rd PWM channel and 12-bit interval timer. | Suitable for simpler control tasks without multi-channel PWM or long-duration interval timing. | Select when firmware size <2 KB and no 12-bit interval timer required - reduces cost without layout change. |
| R5F10Y44ASP#50 | 1 KB Flash, 128 B RAM, same package - reduced memory and peripheral count (no comparator, fewer ADC channels). | Targeted at ultra-low-cost, single-function devices like basic timers or LED controllers. | Choose for minimal-feature implementations where ADC count ≤4 and no comparator needed - lowest bill-of-materials cost. |
Compared with R5F10Y47ASP#50, R5F10Y46ASP#50 offers 50% less Flash/RAM but retains full peripheral set except 12-bit interval timer, while R5F10Y44ASP#50 cuts memory by 75% and removes comparator and 3 ADC channels - making R5F10Y47ASP#50 optimal for feature-rich, battery-sensitive designs needing full analog/mixed-signal capability.

FAQ
What is the maximum operating frequency of the R5F10Y47ASP#50?
The R5F10Y47ASP#50 supports a maximum system clock frequency of 20 MHz using its high-speed on-chip oscillator (±2% accuracy across −20°C to +85°C). When driven by an external crystal or clock source, it accepts up to 20 MHz input under 2.7–5.5 V conditions, or up to 5 MHz under 2.0–2.7 V - ensuring reliable timing across wide supply and temperature ranges in the R5F10Y47ASP#50.
Does the R5F10Y47ASP#50 include an internal voltage reference for the ADC?
Yes, the R5F10Y47ASP#50 includes an internal reference voltage of 0.815 V (typical), dedicated for use with the 10-bit ADC and comparator. This reference is available on the IVREF0 pin and enables accurate analog measurements without external reference components - a confirmed feature specific to 16-pin RL78/G10 variants including the R5F10Y47ASP#50.
How many ADC channels does the R5F10Y47ASP#50 support, and what is the resolution?
The R5F10Y47ASP#50 supports 7 analog input channels (ANI0–ANI6) with 10-bit resolution and a 3.4 µs conversion time. It operates with VDD as reference or optionally uses the internal 0.815 V reference, and supports analog input voltages up to VDD - confirmed in the RL78/G10 datasheet Section 1.6 and electrical specifications for 16-pin products like the R5F10Y47ASP#50.
What package type and pin count does the R5F10Y47ASP#50 use?
The R5F10Y47ASP#50 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65 mm pitch), designated by "SP" in the part number suffix. This matches the 16-pin variant defined in Table 1-1 of the RL78/G10 datasheet and is distinct from the 10-pin LSSOP option - confirmed by Renesas' official ordering information for the R5F10Y47ASP#50.
Can the R5F10Y47ASP#50 operate from a 2.0 V supply?
Yes, the R5F10Y47ASP#50 is fully specified for operation from 2.0 V to 5.5 V. Its high-speed on-chip oscillator runs at 1.25–5 MHz down to 2.0 V, and all DC/AC characteristics - including 46 µA/MHz active current and 0.61 µA STOP mode - are guaranteed across this full range, making the R5F10Y47ASP#50 suitable for single-cell alkaline or lithium primary battery applications.
