Product details
Overview
R5F10Y16DSP#70 from Renesas Electronics is a 16-pin, 2 KB Flash, 256-byte RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power industrial sensor nodes and battery-powered control modules. It operates from 2.0 to 5.5 V, delivers 46 µA/MHz active current, supports 10-bit ADC (7 channels), UART/I²C/CSI interfaces, and integrates a 20 MHz ±2% on-chip oscillator - enabling rapid deployment in smart metering and HVAC actuator designs.
For engineers reviewing the R5F10Y16DSP#70 datasheet, R5F10Y16DSP#70 pinout, R5F10Y16DSP#70 application, or R5F10Y16DSP#70 equivalent, this page provides verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The R5F10Y16DSP#70 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, executing 78% of instructions in 1–2 clock cycles. Its peripheral set includes four 16-bit timer channels (TAU0), one 12-bit interval timer, watchdog timer, and SAU0 serial array unit supporting UART, I²C, and two CSI channels - all configurable via peripheral I/O redirection register (PIOR).
It features dual-clock domain operation: high-speed on-chip oscillator (1.25–20 MHz) for main system clock and 15 kHz low-speed oscillator for RTC-like timing. Power management includes STOP mode (0.61 µA @ 3.0 V) with RAM retention, HALT mode, and selectable power-on reset (SPOR) with four voltage thresholds (2.25–4.45 V).

FAQ
What is the maximum operating frequency of the R5F10Y16DSP#70?
The R5F10Y16DSP#70 supports a maximum system clock frequency of 20 MHz using its high-speed on-chip oscillator, with ±2% accuracy across –20°C to +85°C. When using an external crystal (X1/X2), it operates up to 20 MHz at VDD ≥ 2.7 V or up to 5 MHz at VDD ≥ 2.0 V. The instruction cycle time is as fast as 0.05 µs under these conditions.
Does the R5F10Y16DSP#70 include hardware debugging capability?
Yes, the R5F10Y16DSP#70 integrates a 1-wire on-chip debug interface accessible via the TOOL0 pin (P40). This enables full in-circuit debugging, flash programming, and real-time trace without requiring a dedicated JTAG/SWD connector - reducing PCB area and BOM cost during development and field updates.
How many analog input channels does the R5F10Y16DSP#70 support?
The R5F10Y16DSP#70 supports seven 10-bit analog input channels (ANI0–ANI6), with conversion time of 3.4 µs. It also includes an internal reference voltage (0.815 V typical) and a single comparator (IVCMP0/VCOUT0) - both available only on 16-pin variants like the R5F10Y16DSP#70, enabling compact analog signal conditioning without external components.
What communication interfaces are integrated into the R5F10Y16DSP#70?
The R5F10Y16DSP#70 integrates UART (7-/8-bit), I²C (multi-master capable), and two Simplified SPI (CSI) channels - all implemented in the Serial Array Unit (SAU0). These interfaces share pins via the Peripheral I/O Redirection Register (PIOR), allowing flexible routing to optimize PCB layout and support multiple sensor or actuator protocols simultaneously.
Is the R5F10Y16DSP#70 pin-compatible with other RL78/G10 variants?
Yes, the R5F10Y16DSP#70 is pin-compatible with all 16-pin RL78/G10 variants in SSOP package (e.g., R5F10Y44DSP#70, R5F10Y46DSP#70, R5F10Y47DSP#70), sharing identical pin count, mechanical dimensions, and electrical pin functions. Firmware and layout can be reused across memory variants, enabling scalable design with minimal redesign effort.
