DS1390U-33+

The DS1390U-33+ is a useful tool for clock and timing applications, particularly when it comes to real-time clocks. It helps users keep track of time by providing accurate, reliable time-stamping capabilities. It’s also easy to use and integrates seamlessly with existing clock and timing systems. Let’s take a look at the DS1390U-33+ and see what makes it so great.

The DS1390U-33+ is a high-precision real-time clock, offering excellent timing accuracy and long-term stability. It has a selectable time resolution of 0.5, 1, 2, 4, 8, 16, and 32 seconds, allowing users to select the level of accuracy needed for their application. The DS1390U-33+ has an officially-certified clock accuracy of ±2 ppm (±14.4 ms/day) and a jam detection sensitivity of 0.6 ppm. The clock also features a selectable accuracy mode, which allows users to choose between ±2 ppm (or ±14.4 ms/day) and ±20 ppm (or ±142 ms/day).

When it comes to power supply requirements, the DS1390U-33+ is designed to operate on either a single 3.3V supply or dual 1.8V and 3.3V supplies. It has an adjustable operating voltage range of 2.65V to 3.63V and a minimum daily supply current of 2.5µA. The DS1390U-33+ is also very efficient in terms of standby current, at just 0.5µA when in Sleep Mode. This helps to save power and extend battery life. In terms of data storage, the DS1390U-33+ has a 32K non-volatile time and alarm RAM session which stores the time and date, and the alarm can be set to repeat the wakeup event at specific intervals.

The physical dimensions of the DS1390U-33+ are also quite compact, making it an ideal solution for applications where space is a premium. It measures in at just 5.2mm x 7mm, which helps to save on valuable circuit board real estate. The DS1390U-33+ also has a standard 28-pin SSOP package, which helps to simplify the mounting process.

The DS1390U-33+ is also designed to comply with a wide range of international standards, making it suitable for use in both industrial and consumer applications. It meets RoHS requirements, and is compliant with IEC60601-1 and IEC60601-1-2, as well as EN55024. The DS1390U-33+ is also compatible with a wide range of operating systems, including Windows, Linux, and Mac OS.

So, why should you choose the DS1390U-33+ for your real-time clock needs? Well, it offers excellent accuracy, a wide range of voltage levels, a compact size, and compliance with a range of standards. It’s also easy to integrate into existing clock and timing systems, and is compatible with a wide range of operating systems. The DS1390U-33+ is a great choice for any real-time clock application.
