Product details
Overview
R5F10Y46DSP#70 from Renesas Electronics is a 16-pin, 2 KB Flash, 256-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 high-speed on-chip oscillator ±2% accuracy. It features 7-channel 10-bit ADC, 4-channel 16-bit timer array, UART, I²C, two CSI interfaces, and key interrupt support - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y46DSP#70 datasheet, R5F10Y46DSP#70 pinout, R5F10Y46DSP#70 application, or R5F10Y46DSP#70 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use-value analysis, and two confirmed alternative parts for design continuity and sourcing resilience.
Technical Context
The R5F10Y46DSP#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 clock system supports dual sources: high-speed on-chip oscillator (1.25–20 MHz, ±2% over –20 to +85°C) and external crystal/oscillator (1–20 MHz via X1/X2 pins).
Peripheral integration includes a 7-channel 10-bit ADC with 3.4 µs conversion time and internal 0.815 V reference (16-pin variant only), one comparator with IVREF0/IVCMP0/VCOUT0 terminals, and four independent 16-bit timer channels supporting PWM, input capture, and interval timing - all operating under stop mode with RAM retention down to 0.61 µA at 3.0 V.

FAQ
What is the maximum operating frequency of the R5F10Y46DSP#70?
The R5F10Y46DSP#70 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy over –20 to +85°C. When using an external crystal or clock source, it accepts up to 20 MHz input (1–5 MHz at 2.0–2.7 V). Instruction cycle time is as fast as 0.05 µs at 20 MHz, enabling real-time response in time-critical control loops.
Does the R5F10Y46DSP#70 include an internal voltage reference for the ADC?
Yes, the R5F10Y46DSP#70 includes an internal 0.815 V (typ.) reference voltage (IVREF0) specifically for the 10-bit ADC - accessible on pin P04. This reference enables ratiometric measurements independent of VDD variation, improving accuracy in battery-operated systems where supply voltage drifts during discharge.
Can the R5F10Y46DSP#70 drive LEDs or small relays directly?
Yes, the R5F10Y46DSP#70 supports up to 20 mA sink/source per I/O pin (P00–P07), with total port current limits of 100 mA. This allows direct drive of standard LEDs, optocouplers, and small signal relays without external drivers - reducing BOM count and board area in space-constrained designs.
Is the R5F10Y46DSP#70 pin-compatible with other RL78/G10 variants?
Yes, all 16-pin RL78/G10 devices - including R5F10Y44DSP#70, R5F10Y46DSP#70, and R5F10Y47DSP#70 - share identical SSOP-16 pinout, electrical characteristics, and peripheral mapping. Firmware and hardware designs are interchangeable across these variants, enabling seamless memory-scaling without layout revision.
What debug interface does the R5F10Y46DSP#70 support?
The R5F10Y46DSP#70 integrates a 1-wire on-chip debug interface (TOOL0 pin, P40) compliant with Renesas E2 emulator. This enables full-featured debugging - including breakpoints, watchpoints, and flash programming - using standard Renesas development tools without requiring additional debug headers or SWD/JTAG adapters.
