The X1288V14-4.5AT1 is an entry-level real-time clock (RTC) designed for use in a wide range of applications.

Real time clocks provide precise timekeeping functionality and enable a system to keep track of time across power cycles and other types of shutdowns. The precise timekeeping of an RTC is based on two different elements: an oscillator, which contains the precise timing element and a counter, which accumulates the precise increments of time provided by the oscillator. The X1288V14-4.5AT1 is powered by a 4.5V lithium battery and has a standby current of 50nA, meaning it can last for up to 10 years without any external power input.

It is designed to be highly accurate and has a drift rate (measured in ppm) of ±15ppm from 0°C to 50°C and ±30ppm from -40°C to +85°C. The X1288V14-4.5AT1 has a frequency of 32.768kHz, an input voltage range of 1.8V to 5.5V and an operating temperature range of -40°C to +85°C. It also supports a wide range of features, including BCD coded outputs, a programmable alarm and interrupt output, a watchdog timer and an alarm test feature.

The X1288V14-4.5AT1 is great for a variety of applications, such as in consumer, medical, industrial and automotive markets. It can be used in portable electronic devices, such as wearables, smartphones and tablets, as a general-purpose clock or as an embedded system timer. It is also suitable for high-precision timekeeping applications, such as navigation and navigation systems and clocks or timers in computers and servers.

The X1288V14-4.5AT1’s working principle is based on an oscillator and a counter. The oscillator is the precise timing element and it provides a precise number of clock cycles at a given frequency. The counter accumulates the precise increments of time provided by the oscillator and uses them to track the seconds, minutes, hours and days. The counter can be programmed to issue interrupts and alarm outputs when certain criteria is met. This allows the RTC to be used as a wake-up timer, alarm clock or other time-based events.

The X1288V14-4.5AT1 is a great entry-level real-time clock providing accurate and reliable timekeeping with a wide range of features. Its low cost, long battery life and wide operating temperature range make it perfect for a variety of consumer, medical, industrial and automotive applications.
