With the penetration rate of China's smart door lock market exceeding 50%, 'long battery life, wide application scenarios, and easy implementation' have become the core demands for manufacturers to break through. From the 'no battery replacement' requirement for household door locks, to the 'precise permission time-limit' management for apartments/hotels, and to the 'security time traceability' in commercial scenarios, the combination of an RTC (Real-Time Clock) module and a 32.768kHz crystal forms the crucial 'timing core' determining the user experience and reliability of door locks.

The 'YSN8563MS + YST310S 32.768kHz Crystal Oscillator' solution launched by parent company YXC perfectly meets the full-scenario needs of smart door locks from consumer-grade to industrial-grade applications, making it the preferred choice for manufacturers to reduce costs, improve efficiency, and enhance product competitiveness.

Ultra-Low Power Consumption: Solving Battery Life Anxiety, Extending Standby to 2+ Years
Over 90% of smart door locks are battery-powered, making battery life a direct factor affecting user satisfaction. The YSN8563MS features a typical backup current of only 0.25µA at 3.0V and 25°C, which is 50% lower than the industry average. Paired with the low-power YST310S crystal oscillator (with negligible static power consumption), it enables dry-battery-powered door locks to achieve a battery life of up to 2 years. This solves the after-sales pain point of 'frequent battery changes' while reducing maintenance costs for manufacturers.

Wide Voltage Input, Compatible with Various Power Supply Schemes

The YSN8563MS supports a wide input voltage range of 1.0V to 5.5V, compatible with various power supply schemes such as 1.5V dry batteries, 3.7V lithium batteries, and 5V external power sources. This eliminates the need for additional voltage conversion chips, further reducing power loss and PCB space occupancy.

Multi-Functional Integration, Reducing Costs and Simplifying Design
Smart door locks require core functions like 'timing + alarm + low-voltage protection.' Traditional solutions require a combination of an RTC chip, a separate alarm chip, and a voltage detector, which not only increases BOM costs but also occupies more PCB space. The YSN8563MS directly integrates three core functional modules, replacing multiple chips in one step:

Built-in Alarm Function: Supports minute/hour/date/weekday alarms, enabling direct implementation of features like 'automatic lock,' 'temporary access for cleaning periods,' and 'hotel key card time-limit management' without the need for an external alarm chip.

Built-in Timer: Can be used for periodic status checks (e.g., checking door lock status hourly), simplifying the workload of the main MCU.

Built-in Voltage Low Detector: Automatically sets the VL flag when the supply voltage drops below 1.0V, triggering a low-battery reminder. This prevents clock data loss due to sudden voltage drops without requiring an extra low-voltage detection chip.

Full-Scenario Adaptation, Precise Timing Without Failures
The combination of YSN8563MS and YST310S ensures clock accuracy within ±2 seconds per day across the full temperature range. Whether it's 'timestamp recording for unlock events' in home scenarios or 'permission time calibration' in commercial scenarios, the timing remains precise and reliable, avoiding security vulnerabilities caused by timing deviations.

Why Choose the 'YSN8563MS + YST310S' Combo?

• Stronger Adaptability: The external crystal oscillator design allows flexible switching of the YST310S accuracy grade (e.g., ±20ppm for consumer-grade, ±10ppm for industrial-grade) without changing the RTC chip.
  
• More Stable Supply Chain: YXC's self-developed crystal oscillator and RTC enable integrated 'chip + crystal oscillator' delivery, avoiding compatibility issues caused by mismatched components.
  
• Better Cost Control: As a fully domestic solution, the overall cost is 20%–30% lower compared to imported alternatives. Moreover, standard lead time is stable within 2 weeks, meeting mass production demands.
  

From household fingerprint locks to apartment smart locks, and from hotel key card systems to commercial access management, the 'YSN8563MS RTC + YST310S Crystal Oscillator' combination, with its core advantages of 'functional integration, low-power compatibility, and precise reliability,' has become the essential 'timing benchmark tool' for smart door lock manufacturers to break through the market.
