Product details
Overview
R5F10Y46DSP#10 from Renesas Electronics is a 16-pin, 2 KB Flash, 256-byte RAM RL78/G10 16-bit microcontroller optimized for ultra-low-power embedded control. It operates from 2.0–5.5 V, achieves 46 µA/MHz active current and 0.61 µA STOP mode, and integrates 7-channel 10-bit ADC, UART, two CSI interfaces, and four 16-bit timer channels - deployed in battery-powered sensor nodes and industrial HMI panels.
For engineers reviewing the R5F10Y46DSP#10 datasheet, R5F10Y46DSP#10 pinout, R5F10Y46DSP#10 application, or R5F10Y46DSP#10 equivalent, key selection criteria include its 16-pin SSOP package, 2 KB flash density, -40°C to +85°C industrial temperature grade, integrated high-speed on-chip oscillator (±2% @ 20 MHz), and support for key interrupt (KR0–KR5) and analog input (ANI0–ANI6) functions.
Technical Context
The R5F10Y46DSP#10 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, enabling 78% of instructions in 1–2 clock cycles. Its power management includes selectable power-on reset (SPOR) with four voltage thresholds and dual oscillators: high-speed on-chip (1.25–20 MHz, ±2% accuracy) and low-speed 15 kHz watchdog source.
Peripheral integration centers on the Serial Array Unit (SAU0) supporting UART and two CSI channels, Timer Array Unit (TAU0) with four 16-bit channels (including PWM), and an 8-/10-bit A/D converter with 3.4 µs conversion time across seven analog inputs - all accessible via configurable port pins P00–P07, P40–P41, and P121–P137.

FAQ
What is the maximum operating frequency of the R5F10Y46DSP#10?
The R5F10Y46DSP#10 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy across -40°C to +85°C and 2.0–5.5 V supply. When using an external crystal (X1/X2), it operates up to 20 MHz with appropriate load capacitance and stabilization timing. The minimum instruction execution time is 0.05 µs at 20 MHz, enabling responsive real-time control in the R5F10Y46DSP#10.
Does the R5F10Y46DSP#10 support hardware debugging?
Yes, the R5F10Y46DSP#10 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40). This enables full firmware download, breakpoint setting, and real-time variable inspection without external debug probes. However, Renesas advises against using the debug function in mass-produced units due to potential flash endurance impact - production firmware should be verified pre-deployment and debug disabled in final builds of the R5F10Y46DSP#10.
How many analog input channels does the R5F10Y46DSP#10 provide?
The R5F10Y46DSP#10 provides seven analog input channels (ANI0–ANI6) connected to its 8-/10-bit successive approximation register (SAR) ADC. Conversion time is 3.4 µs at maximum speed, and the ADC supports internal reference voltage (IVREF0) and comparator input (IVCMP0) functions - all confirmed in the 16-pin variant datasheet. This capability is fully implemented in the R5F10Y46DSP#10 and enables direct sensor interfacing without external signal conditioning.
What communication interfaces are integrated in the R5F10Y46DSP#10?
The R5F10Y46DSP#10 integrates UART (7-/8-bit), two Simplified SPI (CSI) channels, and one simplified I²C (IICA) interface. Unlike the 10-pin variants, the 16-pin R5F10Y46DSP#10 supports full I²C master/slave operation on P06/P07 (SCLA0/SDAA0) and dual CSI channels on P01–P02 and P06–P07 - enabling concurrent communication with multiple sensors or displays. All interfaces are accessible without external level shifters on the R5F10Y46DSP#10.
Is the R5F10Y46DSP#10 pin-compatible with other RL78/G10 16-pin variants?
Yes, the R5F10Y46DSP#10 shares identical 16-pin SSOP package dimensions, pinout, and electrical characteristics with other 16-pin RL78/G10 devices including R5F10Y44DSP#10 and R5F10Y47DSP#10. All use the same P00–P07, P40–P41, P121–P137 pin mapping and support identical peripheral configurations via software registers. This allows drop-in replacement within the same memory density family, simplifying design reuse and inventory management for the R5F10Y46DSP#10.
