DS1248Y-70+ Datasheet/PDFDS1248Y-70+ is a Real Time Clock (RTC) IC designed by Dallas Maxim, and as such it has several applications and its working principle is important to understand. This article focuses on the different applications of the IC and its corresponding working principles.
Applications of DS1248Y-70+
The DS1248Y-70+ is primarily used for timing in many different types of devices. It can be used to set the internal timing of microcontrollers, govern the amount of time a device spends in lower power modes and measure battery life. It can also be used to control the timing of a variety of tasks and events.
The DS1248Y-70+ is also capable of storing data, commonly known as ‘data retention’. This means that, when the power is switched off, the values stored in the IC will remain unchanged.
In addition to this, the DS1248Y-70+ has the capability of having alarms and timers programmed into it, so that it can execute certain tasks at specific times. For instance, it can be used to turn on a device at a certain time and can also be used to detect if a device has been left in a certain operating state for too long.
Working Principle
The DS1248Y-70+ works by using a 32.768kHz crystal oscillator as its clock source, which provides the frequency of 32768Hz and thus it has a long battery life. The oscillator is connected to the IC through an internal crystal connection, ensuring that the frequency remains constant.
The output of the oscillator is fed into an internal timer counter, which counts the clock cycles and thus produces a time signal, indicating the passage of time. This time signal is then used to govern the output of the IC.
The IC also has an onboard frequency-adjustable clock, allowing the IC\'s frequency to be adjusted to better suit the application in which it is used. This frequency-adjustable clock is connected to the oscillator, and it can be used to adjust the frequency of the oscillator to a higher or lower frequency, depending on the application.
Finally, the DS1248Y-70+ also has two programmable outputs, which can be used to control the output of the device or activate an alarm or timer. These outputs can be programmed to activate at a certain time or in response to a certain event.
Conclusion
The DS1248Y-70+ is a highly capable Real Time Clock, which has been designed with many different applications in mind. Its working principles are based on the use of a 32.768KHz crystal oscillator, an internal timer counter and a frequency-adjustable clock, to provide reliable and accurate timing. In addition, it also has two programmable outputs, which can be used to control the output of the device or activate an alarm or timer.
