Product details
Overview
R5F10Y46DSP#30 from Renesas is a 16-pin RL78/G10 16-bit microcontroller with 2 KB flash, 256 B RAM, 2.0–5.5 V operation, and ultra-low-power consumption (46 µA/MHz active, 0.61 µA STOP). It integrates a 20 MHz high-speed on-chip oscillator (±2 %), 7-channel 10-bit ADC, UART, two CSI interfaces, I²C, 4-channel 16-bit timer array, and key interrupt support - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F10Y46DSP#30 datasheet, R5F10Y46DSP#30 pinout, R5F10Y46DSP#30 application, or R5F10Y46DSP#30 equivalent, this page delivers verified electrical specs, package mapping to 16-pin SSOP, functional pin roles, real-world use cases, and two validated alternative parts for design flexibility and supply continuity.
Technical Context
The R5F10Y46DSP#30 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) and external crystal/oscillator (1–20 MHz via X1/X2), with automatic fallback and stabilization monitoring via OSTC register.
Peripheral integration includes SAU0 (UART + I²C + CSI), TAU0 (4-channel 16-bit timer with PWM output on 3 channels), 7-channel 10-bit ADC with 3.4 µs conversion time and internal reference (0.815 V), and comparator with IVREF0/IVCMP0/VCOUT0 pins - all configurable via peripheral I/O redirection register (PIOR) without hardware changes.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y46DSP#30?
The R5F10Y46DSP#30 features a high-speed on-chip oscillator rated from 1.25 to 20 MHz, with ±2.0 % accuracy over –20°C to +85°C and ±3.0 % over –40°C to –20°C. This oscillator supports direct system clocking without external crystals, enabling rapid startup and reduced BOM count. The R5F10Y46DSP#30 uses this oscillator for all core and peripheral timing unless configured otherwise via system clock control registers.
Does R5F10Y46DSP#30 support hardware debugging during development?
Yes, the R5F10Y46DSP#30 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40), enabling full breakpoint, step-through, and memory inspection capabilities using Renesas E2 studio and E2 Lite emulator. However, Renesas explicitly cautions against using the debug function in mass-produced units due to potential flash endurance impact - the R5F10Y46DSP#30 debug interface is intended solely for engineering validation.
How many analog input channels does R5F10Y46DSP#30 provide, and what is their resolution and speed?
The R5F10Y46DSP#30 provides seven 10-bit analog input channels (ANI0–ANI6) with a typical conversion time of 3.4 µs. It supports an internal reference voltage of 0.815 V (typ.) and accepts analog inputs up to 2.4 V. All channels share a single SAR ADC module, and conversions can be triggered by software, timer, or external events - making the R5F10Y46DSP#30 suitable for multi-sensor monitoring in compact designs.
What communication interfaces are integrated into R5F10Y46DSP#30?
The R5F10Y46DSP#30 integrates UART (7-/8-bit), one I²C interface (IICA0), and two Simplified SPI (CSI) channels - all implemented within the Serial Array Unit (SAU0). These interfaces share port pins via peripheral I/O redirection, allowing flexible assignment without PCB changes. No CAN, USB, or Ethernet is included; the R5F10Y46DSP#30 targets basic wired/wireless sensor-to-gateway communication.
Is R5F10Y46DSP#30 pin-compatible with other RL78/G10 variants in the 16-pin SSOP package?
Yes, the R5F10Y46DSP#30 is pin-compatible with all 16-pin RL78/G10 variants including R5F10Y44DSP#30 (1 KB flash) and R5F10Y47DSP#30 (4 KB flash). They share identical pin count, physical layout, electrical characteristics, and peripheral mapping - enabling drop-in memory upgrades or downgrades. Firmware compatibility requires matching option byte settings and peripheral initialization sequences specific to each variant's resource allocation.
