Product details
Overview
R5F10Y47DSP#70 from Renesas Electronics is a 16-pin SSOP 8-bit RL78/G10 microcontroller with 4 KB flash, 512 B RAM, 7-channel 10-bit ADC, and integrated high-speed on-chip oscillator (20 MHz ±2%). It operates from 2.0 to 5.5 V and delivers ultra-low power consumption (46 µA/MHz active, 0.61 µA STOP mode), targeting battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F10Y47DSP#70 datasheet, R5F10Y47DSP#70 pinout, R5F10Y47DSP#70 application, or R5F10Y47DSP#70 equivalent, key selection criteria include its 16-pin SSOP package, 7-channel analog input capability, I²C/SPI/UART interface support, and industrial-grade -40°C to +85°C operation with selectable power-on reset.
Technical Context
The R5F10Y47DSP#70 implements the RL78-S1 core-a CISC Harvard architecture with 3-stage pipeline-enabling 78% of instructions in 1–2 clock cycles. Its timer array unit (TAU0) provides four 16-bit channels supporting PWM, capture, and compare functions, while the serial array unit (SAU0) delivers two CSI (SPI-compatible) channels plus one I²C master and one UART.
It integrates a 15 kHz low-speed on-chip oscillator for watchdog and interval timing, a 12-bit interval timer (16-pin only), and comparator with internal reference (IVREF0/IVCMP0/VCOUT0). All peripherals-including ADC, key interrupt (KR0–KR5), and programmable clock/buzzer output (PCLBUZ0)-are mapped to dedicated pins in the 16-pin SSOP layout with full peripheral I/O redirection via PIOR register.

FAQ
What is the maximum operating frequency of the R5F10Y47DSP#70?
The R5F10Y47DSP#70 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy across voltage (2.0–5.5 V) and temperature (−40°C to +85°C). When using an external crystal or clock source, it accepts up to 20 MHz input on X1/X2 or EXCLK pins. The minimum instruction execution time is 0.05 µs at 20 MHz operation, enabling responsive real-time control in the R5F10Y47DSP#70.
Does the R5F10Y47DSP#70 support hardware debugging?
Yes, the R5F10Y47DSP#70 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40). This allows full programming, real-time tracing, and breakpoint debugging without requiring a dedicated JTAG/SWD interface. The debug functionality is fully supported in Renesas' CS+ and e2 studio IDEs, and the R5F10Y47DSP#70 does not require external debug probes for development or field firmware updates.
How many analog input channels does the R5F10Y47DSP#70 have, and what is their resolution?
The R5F10Y47DSP#70 features seven analog input channels (ANI0–ANI6), each supporting 10-bit resolution with a typical conversion time of 3.4 µs. It includes internal reference voltage (0.815 V typ.) and supports external reference down to 2.4 V, enabling accurate measurements across varying supply conditions. This 7-channel capability is exclusive to the 16-pin variants like the R5F10Y47DSP#70 and is confirmed in the device's functional outline and pin configuration tables.
What low-power modes are available on the R5F10Y47DSP#70?
The R5F10Y47DSP#70 offers HALT mode (360–900 µA) and STOP mode (0.61–2.25 µA with RAM retention), both configurable via software. In STOP mode, the high-speed oscillator halts while the 15 kHz low-speed oscillator remains active for watchdog and interval timing. The R5F10Y47DSP#70 achieves 46 µA/MHz in active operation-among the lowest in its class-making it ideal for energy-constrained applications where the R5F10Y47DSP#70 must balance responsiveness and longevity.
Is the R5F10Y47DSP#70 pin-compatible with other RL78/G10 16-pin variants?
Yes, the R5F10Y47DSP#70 shares identical 16-pin SSOP pinout and electrical characteristics with other 16-pin RL78/G10 devices including R5F10Y44DSP#70 and R5F10Y46DSP#70. All share the same peripheral mapping, I/O redirection register (PIOR) behavior, and package dimensions (4.4 × 5.0 mm, 0.65 mm pitch), enabling hardware reuse across firmware variants. This pin compatibility simplifies design scalability and reduces qualification effort for the R5F10Y47DSP#70.
