As digital evidence becomes increasingly important in modern law enforcement, body-worn cameras have become essential tools for police officers, security personnel, and public safety agencies. Accurate timestamping is critical to maintaining the integrity and traceability of recorded video and audio evidence.
However, many body-worn camera systems still face challenges such as excessive power consumption, limited battery life, and timing drift under extreme temperatures. These issues can lead to inaccurate timestamps, unsynchronized recordings, and even compromised evidence reliability.
To address these challenges, YXC introduces the YSN8563 Real-Time Clock (RTC) IC, a low-power and highly reliable timing solution designed for portable devices operating in demanding outdoor environments.
The YSN8563 is an external RTC device with a standard I²C interface. Combined with a 32.768 kHz crystal oscillator (recommended: YST310S), it delivers accurate timekeeping while maintaining ultra-low power consumption.
Main Specifications External Crystal: 32.768 kHz (Recommended: YST310S) Interface: I²C Bus (up to 400 kHz) Operating Voltage: 1.8 V to 5.5 V Backup Timekeeping Voltage: 1.0 V to 5.5 V Typical Current Consumption: 0.25 μA (@3.3 V) Operating Temperature: -40°C to +85°C Package Options: SOP-8, TSSOP-8, MSOP-8 Functions: Calendar, Alarm, Timer, Interrupt Output, Low-Voltage Detection
Precise timestamps are essential for incident reconstruction, legal investigations, and event verification. Even small timing errors can reduce the credibility of recorded evidence and complicate case reviews.
How YSN8563 Solves This
• Provides accurate year, month, day, hour, minute, and second information. • Ensures data consistency by freezing internal time counters during register read operations, preventing inconsistent timestamp data. • Supports low-voltage detection, allowing the system to identify unstable power conditions before timing errors occur.
As a result, recorded evidence remains synchronized, traceable, and legally reliable.
2. High Power Consumption Reduces Battery Life
Body-worn cameras are expected to operate continuously throughout an officer’s shift. Excessive RTC power consumption, although often overlooked, can contribute to unnecessary battery drain over long operating periods.
How YSN8563 Solves This
The YSN8563 is specifically optimized for low-power applications, consuming only 0.25 μA typical current. This extremely low power requirement helps maximize battery life and supports extended field operation without frequent recharging.
3. Timing Drift in Harsh Outdoor Environments
Law enforcement personnel frequently work in challenging conditions, including extreme heat, freezing temperatures, rain, and snow. Conventional timing solutions may experience frequency drift under these conditions, causing multiple devices to lose synchronization.
The YSN8563 supports a wide operating temperature range of -40°C to +85°C, ensuring stable timekeeping performance even in harsh environments. Its robust design minimizes timing drift and helps maintain synchronized timestamps across multiple devices.
Ideal RTC Solution for Body-Worn Camera Systems
With its combination of high-accuracy timekeeping, ultra-low power consumption, and wide-temperature operation, the YSN8563 RTC IC effectively addresses the key challenges faced by modern body-worn cameras.
By providing a reliable time reference, the YSN8563 helps ensure evidence integrity, improves device reliability, and extends battery operating time. It is an ideal RTC solution for body-worn camera manufacturers seeking dependable timing performance in demanding field applications.
