Product details
Overview
R5F10Y44DSP#70 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, and key interrupt support - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y44DSP#70 datasheet, R5F10Y44DSP#70 pinout, R5F10Y44DSP#70 application, or R5F10Y44DSP#70 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use-value metrics, and two confirmed alternative parts for design continuity and sourcing resilience.
Technical Context
The R5F10Y44DSP#70 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 STOP mode (0.61 µA at 3.0 V) and HALT mode (360–900 µA), enabled by selectable power-on reset (SPOR) with four voltage thresholds.
Peripherals are tightly coupled to the low-latency interrupt controller: 7-channel ADC supports 3.4 µs conversion at 2.4 V reference; 4-channel TAU0 provides PWM outputs (3 channels configurable); and dual CSI modules operate as simplified SPI with independent SCK/SI/SO lines - all synchronized to the same high-speed on-chip oscillator or external crystal (1–20 MHz).

FAQ
What is the maximum operating frequency of the R5F10Y44DSP#70?
The R5F10Y44DSP#70 supports a maximum operating frequency of 20 MHz using its high-speed on-chip oscillator, with ±2% accuracy over –20°C to +85°C and full 2.0–5.5 V supply range. External crystal or clock input (X1/X2 or EXCLK) also supports up to 20 MHz, though frequency tolerance depends on resonator selection. The R5F10Y44DSP#70 instruction cycle reaches 0.05 µs at 20 MHz, enabling real-time response in time-critical applications.
Does the R5F10Y44DSP#70 include an internal voltage reference for the ADC?
Yes, the R5F10Y44DSP#70 includes an internal reference voltage of 0.815 V (typical) dedicated to the 10-bit ADC - available on pin P04 as IVREF0. This reference is active only in 16-pin variants like the R5F10Y44DSP#70 and enables accurate analog measurements without external reference ICs. It supports ADC conversions down to 2.4 V supply, making the R5F10Y44DSP#70 suitable for wide-input-range sensing applications.
How many I/O pins does the R5F10Y44DSP#70 have, and what are their drive capabilities?
The R5F10Y44DSP#70 provides 14 CMOS I/O pins in its 16-pin SSOP package, including 4 N-ch open-drain capable pins (P00, P01, P06, P07). Each I/O pin supports up to 20 mA sink current (IOL), with total sink capability of 120 mA across all pins. High-drive capability eliminates external buffer transistors for LEDs and small relays - a key advantage in space-constrained industrial HMI designs using the R5F10Y44DSP#70.
Can the R5F10Y44DSP#70 operate from a 2.0 V supply?
Yes, the R5F10Y44DSP#70 is fully specified for operation from 2.0 V to 5.5 V. At 2.0 V, the high-speed on-chip oscillator operates up to 5 MHz, and the minimum instruction execution time increases to 0.2 µs. All peripherals - including ADC, timers, and serial interfaces - remain functional within datasheet limits. This 2.0 V capability makes the R5F10Y44DSP#70 ideal for energy-harvesting and primary-cell battery systems where voltage sags below 2.5 V occur.
What debug interface does the R5F10Y44DSP#70 support?
The R5F10Y44DSP#70 supports a 1-wire on-chip debug interface via the TOOL0 pin (P40), compatible with Renesas E2 emulator and CS+ IDE. Debug functionality includes full break-point control, memory inspection, and real-time register monitoring - but Renesas explicitly cautions against using the debug circuit in mass-produced units due to flash endurance limitations. For production firmware, the R5F10Y44DSP#70 relies on standard ISP via UART or dedicated programming mode.
