Product details
Overview
R5F10Y47ASP#30 from Renesas is a 16-pin RL78/G10 16-bit microcontroller with 4 KB flash, 512 B RAM, 7-channel 10-bit ADC, and integrated high-speed on-chip oscillator (up to 20 MHz ±2%). It operates from 2.0–5.5 V and delivers ultra-low active current (46 µA/MHz) and sub-µA STOP mode (0.61 µA), targeting battery-powered sensor nodes and smart peripherals.
For engineers reviewing the R5F10Y47ASP#30 datasheet, R5F10Y47ASP#30 pinout, R5F10Y47ASP#30 application, or R5F10Y47ASP#30 equivalent, key selection criteria include its 16-pin SSOP package, 7-channel analog input capability, dual CSI interfaces, I²C master support, and verified operation across –40°C to +85°C industrial ambient conditions.
Technical Context
The R5F10Y47ASP#30 implements the RL78-S1 core-a Harvard-architecture CISC with 3-stage pipeline-enabling 78% of instructions in 1–2 clock cycles. Its timer subsystem includes four 16-bit TAU channels, one 12-bit interval timer, and a 15 kHz watchdog, all configurable via peripheral I/O redirection register (PIOR).
It integrates dual serial interfaces: one UART (7-/8-bit), one simplified I²C (IICA0), and two CSI channels (CSI00/CSI01), plus a single comparator with internal reference (IVREF0) and VCOUT0 output-functions confirmed exclusive to 16-pin RL78/G10 variants per datasheet Table 1-3 and Section 1.6.

FAQ
What is the maximum operating frequency of the R5F10Y47ASP#30?
The R5F10Y47ASP#30 supports a maximum high-speed on-chip oscillator frequency of 20 MHz (±2% accuracy over –20°C to +85°C). When using an external crystal or clock source, it accepts up to 20 MHz input (1–5 MHz at VDD < 2.7 V). The minimum instruction execution time is 0.05 µs at 20 MHz, enabling responsive real-time control in the R5F10Y47ASP#30.
Does the R5F10Y47ASP#30 support I²C communication?
Yes, the R5F10Y47ASP#30 includes a dedicated I²C bus interface (IICA0) supporting master-only operation. Pins P06 (SCLA0) and P07 (SDAA0) are assigned to this function in the 16-pin SSOP package. This interface is distinct from the simplified I²C (IIC00) on P01/P02 and is confirmed in datasheet Table 1-3 and Section 1.6 as exclusive to 16-pin RL78/G10 variants like the R5F10Y47ASP#30.
What are the low-power modes supported by the R5F10Y47ASP#30?
The R5F10Y47ASP#30 supports three primary low-power modes: HALT (360–900 µA), STOP (0.61–2.25 µA), and ultra-low STOP with RAM retention. In STOP mode, the CPU, flash, and most peripherals halt while retaining RAM content and allowing wake-up via external interrupt, key interrupt (KR0–KR5), or timer event-verified in datasheet Section 2.3.2 and Figure 1-5 block diagram for 16-pin products.
Can the R5F10Y47ASP#30 drive LEDs directly?
Yes, the R5F10Y47ASP#30 can drive standard LEDs directly: its I/O pins support up to 20 mA sink/source per pin (e.g., P00–P07, P40–P41), with total port current limits defined in Section 2.3.1. For example, P00 (TxD0) or P04 (TO01) can source/sink sufficient current for indicator LEDs without external drivers-provided total port current stays within 100 mA (P00–P07) and duty cycle ≤70% per datasheet Note 3.
Is there an internal voltage reference for the ADC in the R5F10Y47ASP#30?
Yes, the R5F10Y47ASP#30 includes an internal reference voltage (IVREF0) of 0.815 V (typical), accessible on pin P04. This reference is explicitly documented for 16-pin products in datasheet Table 1-3 and Section 1.6, and enables ratiometric ADC measurements independent of VDD fluctuations-critical for precision analog sensing in the R5F10Y47ASP#30.
