Product details
Overview
R5F10Y47ASP#10 from Renesas Electronics is a 16-pin, 4 KB Flash, 512 B RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power embedded control. It operates from 2.0 to 5.5 V, achieves 46 µA/MHz active current and 0.61 µA STOP mode, and integrates a 20 MHz ±2% on-chip oscillator, 7-channel 10-bit ADC, 4-channel 16-bit timer array, UART, two CSI interfaces, and I²C - deployed in battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10Y47ASP#10 datasheet, R5F10Y47ASP#10 pinout, R5F10Y47ASP#10 application, or R5F10Y47ASP#10 equivalent, key selection criteria include its 16-pin SSOP package, 4 KB flash/512 B RAM configuration, integrated comparator and internal reference (IVREF0/IVCMP0), 12-bit interval timer, and support for key interrupt (KR0–KR5) and programmable buzzer output (PCLBUZ0).
Technical Context
The R5F10Y47ASP#10 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, enabling 78% of instructions in 1–2 clock cycles. Its power management includes selectable power-on reset (SPOR) with four voltage thresholds (2.25–4.45 V), low-speed 15 kHz watchdog timer, and HALT/STOP modes with RAM retention.
Peripheral integration targets cost-sensitive, space-constrained applications: dual CSI (SPI-compatible) channels enable daisy-chain sensor interfaces; the 7-channel ADC supports 3.4 µs conversion at 10-bit resolution with internal 0.815 V reference; and the 4-channel TAU0 supports PWM outputs on TO00–TO03 with configurable dead-time control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10Y46ASP#10 | 2 KB Flash / 256 B RAM; identical 16-pin SSOP package and peripheral set. | Suitable for simpler firmware with no floating-point math or large lookup tables. | Select when application code size remains under 1.8 KB and RAM usage stays below 220 B to reduce BOM cost. |
| R5F10Y44ASP#10 | 1 KB Flash / 128 B RAM; same package and core, but reduced memory and no comparator/IVREF0. | Targeted at basic timer/control tasks without analog thresholding or sensor fusion. | Choose only for fixed-function logic where ADC use is limited to single-channel calibration or no comparator functionality is needed. |
Compared with R5F10Y47ASP#10, R5F10Y46ASP#10 offers 50% less Flash/RAM at lower cost but retains all analog and timer features; R5F10Y44ASP#10 removes the comparator and internal reference, limiting its use in closed-loop analog monitoring - making R5F10Y47ASP#10 the optimal choice for mixed-signal edge intelligence.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y47ASP#10?
The R5F10Y47ASP#10 features a high-speed on-chip oscillator rated from 1.25 to 20 MHz, with ±2% accuracy over −20°C to +85°C and ±3% over −40°C to −20°C at 2.0–5.5 V supply. This eliminates external crystal cost while supporting UART baud rates up to 3.3 Mbps and deterministic real-time execution in the R5F10Y47ASP#10.
Does R5F10Y47ASP#10 support hardware-based key interrupt scanning?
Yes, the R5F10Y47ASP#10 supports six dedicated key return (KR0–KR5) pins mapped across P01–P04, P40, and P125. These enable hardware-accelerated matrix keypad scanning with automatic wake-up from STOP mode, reducing CPU load and power consumption versus software polling - a core feature of the R5F10Y47ASP#10's HMI subsystem.
Can R5F10Y47ASP#10 operate from a single 3.0 V coin cell battery throughout its lifetime?
Yes - the R5F10Y47ASP#10 draws only 0.61 µA in STOP mode with RAM retention at VDD = 3.0 V, and 46 µA/MHz during active operation. With duty-cycled sensor reads and efficient sleep/wake cycles, it sustains >5-year operation on a CR2032 coin cell, validated per Renesas' RL78/G10 electrical specifications for the R5F10Y47ASP#10.
What analog features distinguish R5F10Y47ASP#10 from lower-memory RL78/G10 variants?
The R5F10Y47ASP#10 uniquely includes the comparator (IVCMP0/VCOUT0) and internal 0.815 V reference (IVREF0) - absent in R5F10Y44ASP#10 and R5F10Y46ASP#10. These enable hardware-level overvoltage/undervoltage detection, windowed analog monitoring, and self-referenced ADC measurements without external components - a defining capability of the R5F10Y47ASP#10.
Is the R5F10Y47ASP#10 pin-compatible with other RL78/G10 16-pin packages?
Yes - all RL78/G10 16-pin SSOP variants (R5F10Y44ASP#10, R5F10Y46ASP#10, R5F10Y47ASP#10) share identical pinouts, electrical characteristics, and package dimensions (PRSP0016JC-B). Firmware and PCB layouts are interchangeable; only Flash/RAM size and analog feature availability differ - enabling scalable design reuse across the R5F10Y47ASP#10 family.
