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 "battery-free" requirement for household door locks to the "precise permission validity" management for apartments/hotels, and further to the "security time traceability" in commercial scenarios, the combination of RTC real-time clock module and 32.768kHz crystal oscillator is the "time benchmark core" that determines the door lock experience and reliability.
The "YSN8563MS +YST310S 32.768kHz crystal oscillator" solution launched by YXC perfectly matches the full-scenario requirements of smart door locks from civil to industrial level, and becomes the preferred choice for manufacturers to reduce costs, increase efficiency and improve product competitiveness.
Ultra-low power consumption: Solving the battery life anxiety of door locks, extending standby time to over 2 years
Over 90% of smart door locks are battery-powered, and their battery life directly impacts user satisfaction. The YSN8563MS, operating at 3.0V and 25°C, delivers a typical standby current of just 0.25µA—50% below the industry average. Paired with the YST310S low-power crystal oscillator (with negligible static power consumption), it extends the battery life of dry-cell door locks to two years, eliminating the pain point of frequent battery replacements and reducing maintenance costs for manufacturers.
Wide voltage input, compatible with multiple power supply solutions
YSN8563MS supports 1.0~5.5V wide voltage input, compatible with 1.5V dry battery, 3.7V lithium battery, 5V external power supply and other power supply solutions, no additional voltage conversion chip, further reduce power loss and PCB space occupancy.
Multifunction integration, cost reduction and simplified design
Smart door locks require core functions like timing, alarm, and low-voltage protection. Traditional solutions rely on RTC, standalone alarm chips, and voltage detectors, which not only increase BOM costs but also occupy more PCB space. The YSN8563MS directly integrates three core modules, replacing multiple chips in a single step.
· Built-in alarm function: Supports minute, hour, date, and day-of-the-week alarms, enabling features like "time-limited reverse lock", "temporary authorization for cleaning periods", and "hotel room card expiration management" without requiring external alarm chips.
· Built-in timer: Enables periodic status checks (e.g., hourly door lock status monitoring) to reduce the workload on the main control MCU.
· Built-in low-voltage detector: When the supply voltage drops below 1.0V, it automatically sets the VL flag to trigger a low-power alert, preventing clock data loss caused by voltage spikes, eliminating the need for an external low-voltage detection chip.
Adaptive to all scenarios, precise timing without dropouts
The YSN8563MS and YST310S pair ensures clock accuracy within ±2 seconds daily across all temperature ranges. Whether for home-use 'lock unlock timestamp recording' or commercial 'permission validity calibration', this system delivers precise and reliable performance, effectively preventing security vulnerabilities caused by timing deviations.
Why choose the "YSN8563MS+YST310S" combination?
· Enhanced adaptability: The external crystal oscillator design allows flexible switching of the YST310S's precision level (e.g., ±20ppm for civilian-grade or ±10ppm for industrial-grade) without RTC chip replacement.
· Enhanced supply chain stability: YXC's proprietary crystal oscillator (RTC) delivers integrated' chip + oscillator' solutions, eliminating compatibility issues caused by oscillator-RTC mismatches.
· Cost control is enhanced: The domestically sourced combination reduces overall costs by 20% to 30% compared to imported options, with a stable delivery time of under two weeks, meeting the requirements for mass production.
From residential fingerprint locks to smart apartment locks, from hotel room card systems to commercial access control, the "YSN8563MS RTC+YST310S crystal oscillator" has become the "time benchmark tool" for smart lock manufacturers to break through the market, with its core advantages of "functional integration, low-power compatibility, and precise reliability".
