Product details
Overview
R5F10Y16ASP#V0 from Renesas is a 10-pin, 1 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 ±2% on-chip oscillator. It features 4-channel 10-bit ADC, 1× UART, 1× I²C master, 1× simplified SPI (CSI), 2× 16-bit timers, and key interrupt support - deployed in battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F10Y16ASP#V0 datasheet, R5F10Y16ASP#V0 pinout, R5F10Y16ASP#V0 application, or R5F10Y16ASP#V0 equivalent, this page delivers verified technical context, package-validated pin functions, low-power design trade-offs, and real-world substitution guidance for cost-sensitive, space-constrained embedded systems.
Technical Context
The R5F10Y16ASP#V0 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 STOP mode (0.56 µA), HALT mode (350–820 µA), and selectable power-on reset (SPOR) with four voltage thresholds (2.25–4.45 V).
Peripherals are tightly coupled to the 10-pin LSSOP package: only P00–P04 and P40/P125/P137 are available, limiting analog inputs to ANI0–ANI3, timer outputs to TO00/TO01, and communication to UART0 + IICA0 + CSI00 - no I²C multi-master, comparator, or interval timer, which are exclusive to 16-pin variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10Y14ASP#V0 | 1 KB Flash, 128 B RAM, same 10-pin LSSOP package and peripherals - lower RAM limits complex state machines | Suitable for simpler remotes with <100-line firmware; insufficient for UART+ADC+key scan with buffering | Select when firmware size ≤800 B and RAM usage <100 B - reduces cost by ~8% but constrains feature depth |
| R5F10Y17ASP#V0 | 4 KB Flash, 512 B RAM, identical pinout and peripheral set - adds headroom for OTA updates and larger sensor fusion algorithms | Required for designs needing field-upgradable firmware or dual-sensor correlation (e.g., temp + humidity + motion) | Choose when future feature expansion or bootloader storage is mandatory - same PCB, no layout change |
Compared with R5F10Y14ASP#V0, the R5F10Y16ASP#V0 provides 128 B extra RAM for interrupt-safe UART buffers and ADC sample queues; versus R5F10Y17ASP#V0, it trades 3 KB Flash for lower unit cost while retaining full peripheral compatibility for fixed-function deployments.

FAQ
What is the maximum operating frequency of the R5F10Y16ASP#V0?
The R5F10Y16ASP#V0 supports a maximum system clock frequency of 20 MHz using its internal high-speed on-chip oscillator, rated at ±2% accuracy across -20 to +85°C and 2.7–5.5 V. External crystal or clock input up to 20 MHz is also supported, but the R5F10Y16ASP#V0's 10-pin LSSOP package omits X1/X2 pins - so external oscillation requires EXCLK injection on P122, limiting practical use to square-wave sources.
Does the R5F10Y16ASP#V0 include an integrated ADC?
Yes, the R5F10Y16ASP#V0 integrates a 10-bit successive approximation register (SAR) ADC with four input channels (ANI0–ANI3). It achieves 3.4 µs conversion time and supports 2.4 V reference - enabling precise thermistor, potentiometer, or light sensor measurements without external signal conditioning in most cases.
Can the R5F10Y16ASP#V0 operate from a 2.0 V supply?
Yes, the R5F10Y16ASP#V0 is fully specified for 2.0–5.5 V operation. At 2.0 V, the high-speed on-chip oscillator is limited to 1.25–5 MHz, instruction cycle time increases to 0.2–0.8 µs, and I/O drive strength reduces - but STOP mode current remains 0.56 µA, making it viable for single-cell alkaline or NiMH applications with brown-out detection disabled.
What debug interface does the R5F10Y16ASP#V0 support?
The R5F10Y16ASP#V0 supports 1-wire on-chip debugging via the TOOL0 pin (P40), compatible with Renesas E2 emulator and CS+ IDE. This interface enables full flash programming, breakpoint setting, and real-time variable monitoring - but must not be used in mass-produced units due to flash endurance limitations per Renesas specification R01DS0207EJ0321.
Is the R5F10Y16ASP#V0 pin-compatible with other RL78/G10 10-pin variants?
Yes, the R5F10Y16ASP#V0 shares identical 10-pin LSSOP pinout and electrical characteristics with R5F10Y14ASP#V0 and R5F10Y17ASP#V0. All three support the same peripheral mapping (e.g., UART on P00/P01, ADC on P01–P04), allowing firmware reuse and drop-in replacement - though Flash/RAM differences require binary validation before substitution.
