Product details
Overview
R5F10Y46DSP#50 from Renesas Electronics is a 16-pin, 2 KB Flash, 256-byte RAM RL78/G10 16-bit microcontroller featuring the RL78-S1 core, 20 MHz high-speed on-chip oscillator (±2% over −20 to +85°C), 7-channel 10-bit ADC (3.4 µs conversion), and ultra-low power operation (46 µA/MHz active, 0.61 µA STOP mode). It targets battery-powered sensor nodes and compact industrial control modules requiring reliable mixed-signal integration in SSOP packaging.
For engineers reviewing the R5F10Y46DSP#50 datasheet, R5F10Y46DSP#50 pinout, R5F10Y46DSP#50 application, or R5F10Y46DSP#50 equivalent, key selection criteria include its 16-pin SSOP package with 7 analog inputs, dual CSI interfaces, I²C master, UART, 4-channel TAU timer, and support for −40°C to +85°C industrial ambient operation with selectable power-on reset.
Technical Context
The R5F10Y46DSP#50 implements the RL78-S1 CISC core with 3-stage pipeline and Harvard architecture, enabling 78% of instructions in 1–2 clock cycles. Its peripheral set includes a 7-channel 10-bit ADC with internal reference input (IVREF0) and comparator (IVCMP0/VCOUT0), plus four 16-bit timer array unit (TAU) channels supporting PWM output on TO00–TO03.
It supports dual clock domains: high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy at VDD = 2.7–5.5 V) and low-speed 15 kHz on-chip oscillator. Communication is handled by one UART, one I²C master (IICA0), and two simplified SPI (CSI00/CSI01) channels - all mapped to dedicated pins in the 16-pin SSOP layout with full peripheral I/O redirection via PIOR register.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10Y46DSP#50?
The R5F10Y46DSP#50 features a high-speed on-chip oscillator adjustable from 1.25 MHz to 20 MHz, with ±2.0% accuracy over −20°C to +85°C and ±3.0% over −40°C to −20°C at VDD = 2.7–5.5 V. This eliminates external crystal needs in many applications while ensuring timing predictability for UART baud generation and PWM control.
Does R5F10Y46DSP#50 support hardware I²C multi-master operation?
No, R5F10Y46DSP#50 supports only I²C master mode (IICA0) - not multi-master. The datasheet explicitly states multi-master capability is limited to 16-pin RL78/G10 variants "only for 16-pin product" in the I²C section, but Table 1-3 and Section 1.6 confirm R5F10Y46DSP#50 implements IICA0 as master-only; no arbitration or slave-mode registers are present.
How many analog input channels does R5F10Y46DSP#50 provide, and what is their resolution and conversion time?
R5F10Y46DSP#50 provides seven 10-bit analog input channels (ANI0–ANI6) with a typical conversion time of 3.4 µs. It supports 2.4 V reference voltage and includes dedicated IVREF0 and IVCMP0 pins for comparator use, enabling simultaneous analog sensing and threshold detection without external components.
What low-power modes are available in R5F10Y46DSP#50, and what is the minimum current draw?
R5F10Y46DSP#50 offers HALT and STOP modes. In STOP mode with RAM retention, it draws 0.61 µA (typical) at VDD = 3.0 V. The STOP mode disables all clocks except the 15 kHz low-speed oscillator, allowing wake-up via INTP0–INTP3, key return (KR0–KR5), or timer events - ideal for battery longevity in intermittent-sensing applications.
Is R5F10Y46DSP#50 pin-compatible with other RL78/G10 16-pin variants like R5F10Y44DSP#50 or R5F10Y47DSP#50?
Yes, R5F10Y46DSP#50 is fully pin-compatible with R5F10Y44DSP#50 and R5F10Y47DSP#50 - all share identical 16-pin SSOP package, pin mapping, and peripheral assignment. Memory differences (1 KB/2 KB/4 KB Flash, 128/256/512-byte RAM) do not affect pin function or electrical behavior, enabling drop-in replacement during design iteration or volume ramp.
