Product details
Overview
R5F10Y47DSP#30 from Renesas is a 16-pin, 4 KB Flash, 512-byte 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 peripherals.
For engineers reviewing the R5F10Y47DSP#30 datasheet, R5F10Y47DSP#30 pinout, R5F10Y47DSP#30 application, or R5F10Y47DSP#30 equivalent, key selection criteria include its 16-pin SSOP package, 4 KB flash/512 B RAM configuration, STOP-mode current of 0.61 µA at 3.0 V, 7-channel ADC with internal reference, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F10Y47DSP#30 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute in 1–2 clock cycles. Its power management includes selectable power-on-reset (SPOR) with four voltage thresholds and dual oscillators: high-speed on-chip (1.25–20 MHz) and low-speed 15 kHz watchdog source.
Peripheral integration targets cost-sensitive embedded systems: one UART (7-/8-bit), two simplified SPI (CSI) channels, one I²C master, 4 TAU timer channels supporting PWM output, and a dedicated 12-bit interval timer - all operating under single-supply 2.0–5.5 V with full -40°C to +85°C ambient rating.

FAQ
What is the maximum operating frequency of the R5F10Y47DSP#30?
The R5F10Y47DSP#30 supports a maximum system clock frequency of 20 MHz using its high-speed on-chip oscillator (±2% accuracy over voltage and temperature). When using an external crystal or clock source, it accepts up to 20 MHz input (at VDD ≥ 2.7 V) or 5 MHz (at VDD ≥ 2.0 V). The minimum instruction execution time is 0.05 µs at 20 MHz, confirming full performance compliance at rated speed.
Does the R5F10Y47DSP#30 include an internal voltage reference for the ADC?
Yes, the R5F10Y47DSP#30 includes an internal reference voltage (IVREF0) of 0.815 V (typical), accessible on pin P04. This reference is explicitly supported for use with the 10-bit ADC and comparator functions - confirmed in Table 1-3 and Section 1.6 of the datasheet for 16-pin variants like R5F10Y47DSP#30.
How many analog input channels does the R5F10Y47DSP#30 support?
The R5F10Y47DSP#30 supports seven analog input channels (ANI0 through ANI6), mapped to pins P01, P02, P03, P04, P05, P06, and P07 respectively. This is specified in Table 1-3 (Alternate Function of 16-pin products) and confirmed in Section 1.6 "Outline of Functions", which states "7 channels" for 16-pin RL78/G10 devices including R5F10Y47DSP#30.
What is the STOP mode current consumption of the R5F10Y47DSP#30?
The R5F10Y47DSP#30 consumes 0.61 µA (typical) in STOP mode at VDD = 3.0 V, with RAM retention enabled. The datasheet specifies a maximum of 2.25 µA under worst-case conditions (Page 17, Table 2.3.2(2)). This value excludes current drawn by the 12-bit interval timer and watchdog timer - both of which may be independently disabled to achieve lowest possible quiescent draw.
Is the R5F10Y47DSP#30 pin-compatible with other RL78/G10 16-pin variants?
Yes, the R5F10Y47DSP#30 shares identical pinout, package (16-pin SSOP), and peripheral mapping with all other 16-pin RL78/G10 devices including R5F10Y44DSP#30 and R5F10Y46DSP#30. Pin functions are defined in Table 1-3 and Figure 1-3, and no variant-specific pin reassignments exist - enabling drop-in replacement across memory configurations within the same package family.
