Product details
Overview
R5F10Y16ASP#X0 from Renesas Electronics is a 10-pin, 1 KB Flash, 256-byte RAM RL78/G10 16-bit microcontroller with ultra-low-power operation (46 µA/MHz active, 0.56 µA STOP), 2.0–5.5 V supply, and integrated 20 MHz ±2% on-chip oscillator. It features 4-channel 10-bit ADC, UART, I²C, simplified SPI (CSI), 2-channel 16-bit timer array, and key interrupt support - deployed in battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F10Y16ASP#X0 datasheet, R5F10Y16ASP#X0 pinout, R5F10Y16ASP#X0 application, or R5F10Y16ASP#X0 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use-value analysis, and two confirmed alternative parts for low-voltage embedded control designs requiring compact footprint and sub-1 µA standby current.
Technical Context
The R5F10Y16ASP#X0 implements the RL78-S1 core - a Harvard-architecture CISC with 3-stage pipeline, where 78% of instructions execute 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 at −20 to +85°C) and low-speed 15 kHz watchdog-capable oscillator.
Peripherals are tightly coupled to the 10-pin LSSOP package: 4 analog inputs (ANI0–ANI3), 6-key return (KR0–KR5), 2 external interrupts (INTP0, INTP1), and serial interfaces limited to UART0, IIC00, and CSI00 - all mapped to shared pins via fixed alternate function assignment (no PIOR remapping in 10-pin variants per datasheet Section 1.3.1).

FAQ
What is the maximum operating frequency of the R5F10Y16ASP#X0?
The R5F10Y16ASP#X0 supports a maximum high-speed on-chip oscillator frequency of 20 MHz with ±2% accuracy across −20 to +85°C. When using external crystal (X1/X2) or EXCLK, max frequency is 20 MHz at VDD ≥ 2.7 V or 5 MHz at VDD ≥ 2.0 V. The R5F10Y16ASP#X0 achieves a minimum instruction cycle of 0.05 µs under these conditions.
Does the R5F10Y16ASP#X0 include an internal voltage reference for the ADC?
No, the R5F10Y16ASP#X0 does not include an internal reference voltage (IVREF0) or comparator (IVCMP0/VCOUT0). These features are exclusive to 16-pin RL78/G10 variants (e.g., R5F10Y46ASP#X0). The R5F10Y16ASP#X0's 4-channel 10-bit ADC uses VDD as reference and supports analog inputs up to VDD.
Can the R5F10Y16ASP#X0 drive LEDs directly without external transistors?
Yes - the R5F10Y16ASP#X0 supports up to 20 mA sink current per I/O pin (P00–P04, P40) at VDD ≥ 4.0 V, enabling direct driving of standard 20 mA LEDs. For higher-current loads or voltage-level shifting, external drivers remain recommended. Always observe total package current limits: ≤60 mA for P00–P04 combined.
Is the R5F10Y16ASP#X0 pin-compatible with other RL78/G10 10-pin variants?
Yes - all RL78/G10 10-pin variants (R5F10Y14ASP#X0, R5F10Y16ASP#X0, R5F10Y17ASP#X0) share identical LSSOP-10 pinout, electrical characteristics, and peripheral mapping. Firmware and hardware are interchangeable; only Flash/RAM capacity differs. No PCB changes are needed when upgrading from R5F10Y14ASP#X0 to R5F10Y16ASP#X0.
What debug interface does the R5F10Y16ASP#X0 support?
The R5F10Y16ASP#X0 supports 1-wire on-chip debugging via the TOOL0 pin (P40), compatible with Renesas E2 emulator and CS+ IDE. Debugging consumes flash endurance - Renesas explicitly warns against using on-chip debug in mass production due to potential reliability impact. Production units should disable debug functionality post-programming.
