Product details
Overview
R5F10Y44DSP#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, and key interrupt support - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y44DSP#30 datasheet, R5F10Y44DSP#30 pinout, R5F10Y44DSP#30 application, or R5F10Y44DSP#30 equivalent, this page delivers verified technical context, package-confirmed pin functions, real-world use-value metrics, and two validated alternative parts for design continuity and sourcing flexibility.
Technical Context
The R5F10Y44DSP#30 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, executing 78% of instructions 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 core via dedicated bus arbitration: the 7-channel ADC supports 3.4 µs conversion at 2.4 V reference; the 4-channel TAU0 timer provides PWM outputs (3 channels configurable); and dual CSI modules operate independently as simplified SPI or I²C masters/slaves - all synchronized to either fIH (on-chip oscillator) or fMX (external crystal/EXCLK).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78-S1 16-bit CISC with 3-stage pipeline; 78% instructions execute in 1–2 cycles - enables deterministic real-time response in motor control loops. |

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y44DSP#30?
The R5F10Y44DSP#30 integrates a high-speed on-chip oscillator rated for 1.25–20 MHz operation, with ±2.0% accuracy over -20°C to +85°C and ±3.0% over -40°C to -20°C at VDD = 2.0–5.5 V. This eliminates external crystal requirements in applications where timing tolerance ≤2% is acceptable, such as LED dimming or sensor polling.
Does R5F10Y44DSP#30 support hardware debug during production deployment?
No - the R5F10Y44DSP#30's on-chip debug function (via TOOL0 pin) is intended solely for development and evaluation. Renesas explicitly prohibits its use in mass-produced units due to flash memory wear-out risk beyond guaranteed rewrite cycles; production firmware must be verified pre-deployment and debug disabled in final builds.
How many analog input channels does R5F10Y44DSP#30 provide, and what is their resolution?
The R5F10Y44DSP#30 provides seven 10-bit analog input channels (ANI0–ANI6) with 3.4 µs conversion time. It supports an internal 0.815 V reference voltage (IVREF0) on P04 and operates down to 2.4 V supply - enabling precise ratiometric measurements without external voltage references in battery-powered designs.
Can R5F10Y44DSP#30 drive LEDs or relays directly without external drivers?
Yes - the R5F10Y44DSP#30 supports up to 20 mA sink current per I/O pin (P00–P07, P40, P41) and includes four N-ch open-drain outputs tolerant to VDD. This allows direct driving of standard LEDs, small-signal relays, and logic-level MOSFET gates without buffer transistors or driver ICs in low-power control applications.
What package type and pin count does R5F10Y44DSP#30 use?
The R5F10Y44DSP#30 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65 mm pitch) with industrial-grade temperature rating (-40°C to +85°C). Pin configuration matches Table 1-3 in the R01DS0207EJ0321 datasheet, including dedicated ADC, timer, UART, and key interrupt functions mapped to specific port pins.
