The DS1248W-120IND is a high-performance real-time clock module that combines low-power operation, advanced features, and extreme accuracy. Designed for clock/timing-related functions requiring precision timekeeping, this small, lightweight module helps extend the overall battery life of a device or system by consuming as low as 200nA power draw during RTC operation.
Overview
The DS1248W-120IND real-time clock module is a low-power, highly accurate, clock/timing device ideal for applications needing precise timekeeping but are battery-powered. This device is based on the Lithium-ion cell which provides the device with accurate and reliable timekeeping, even when the system is powered down. It integrates a power regulator, clock oscillator, crystal resonator and a temperature sensor into a single module, reducing the overall system size and complexity. It also comes in a wide variety of sizes and voltage requirements so it can be used in a range of applications.
Application Field of DS1248W-120IND
The DS1248W-120IND is mainly used in applications that require precise timekeeping. Examples include timekeeping for activity tracking, time and attendance monitoring, energy efficiency tracking, logging, surveillance systems and other similar applications. The module also offers low-power, reliable operation in harsh and hostile environments. Its low-power, real-time clock feature allows it to be used in temperature, humidity and smoke detectors, portable electronic devices and other applications where accurate timing and energy efficiency are critical.
Working Principle of DS1248W-120IND
The DS1248W-120IND module is based on a low-power industry-standard architecture. Its design includes a power regulator, clock oscillator, crystal resonator and a temperature sensor. The 1-wire master clock, or controller, then keeps track of the time as well as other system parameters like temperature. The clock oscillator uses an external quartz crystal to control the oscillation frequency which is measured by the master clock to deliver consistent, accurate timing. The device also auto-calibrates against the temperature, ensuring accurate timekeeping in temperature-sensitive environments. The power regulator integrated into the device is designed for extremely low power operation. The main features of the module are:
- High precision and accuracy from the quartz crystal inside the module ensures reliable timekeeping even in temperatures up to 85C.
- Integrated temperature sensor allows the device to adjust frequency and ensure accurate timekeeping.
- Extremely low power consumption maintains long battery life even in harsh, power-constrained environments.
- Compact, lightweight design is ideal for applications where space is limited.
Conclusion
The DS1248W-120IND real-time clock module offers a reliable, low-power solution for clock/timing applications requiring precise timekeeping and accuracy. Its compact, lightweight design allows it to be used in space-restricted or battery-powered devices, making it an ideal choice for activity tracking, time and attendance monitoring, energy efficiency tracking, logging, surveillance systems and other similar applications. Its low-power operation, precision timing and temperature compensation features provide users with an exceptional and reliable solution.
