The X1288V14-2.7A is a real time clock (RTC) with integrated temperature compensation circuitry. It is part of the X1288 series that offer extended temperature range (−20°C to +85°C) and power supply voltage stability (VS from 2.7V to 5.5V). The X1288V14-2.7A is the newest version of the X1288 series, which comprises modules that are compatible in terms of features and features, in addition to the extended temperature range. The X1288V14-2.7A offers enhanced performance for a wide range of applications.

Application Field

The X1288V14-2.7A is designed to provide a cost effective, low power RTC solution that is suitable for use in a range of embedded systems. It can be used as an integral component in embedded systems, including process and industrial control, office control systems, home control systems, automotive and security systems, medical electronic equipment, and other areas where accurate and reliable date/time management is required. The X1288V14-2.7A can also be used as a general-purpose timer.

Working Principle

The X1288V14-2.7A uses a crystal oscillator to generate an accurate time signal. The signal is then used to drive a binary counter, which is used to store the time. The binary counter is reset to a particular time on power-up and the time signal is used to increment the counter. The counter can be read at any time and the current time displayed. The time signal is also used to control other functions, such as alarm, calibration, and power management.

The X1288V14-2.7A also contains integrated temperature sensing circuitry that enables it to automatically adjust the oscillator frequency in order to compensate for temperature fluctuations. This provides more accurate and stable timekeeping over a wide temperature range. A calibration register is provided that allows the user to manually adjust the oscillator frequency if necessary. The X1288V14-2.7A can also be used as an alarm timer; an alarm output can be enabled when the current time reaches a pre-set time.

The X1288V14-2.7A also has power management features, such as automatic power down/wake-up and a power-saving mode that can save up to 60% of power consumption. Low power consumption is essential for battery-powered applications, where power must be conserved for extended operation time. The X1288V14-2.7A also provides additional features, such as a 32-kHz output for peripheral devices, and a programmable time base for synchronization.

Conclusion

The X1288V14-2.7A is a low power RTC solution with integrated temperature compensation circuitry and a wide range of features. It is designed to provide accurate date/time management in a variety of embedded systems, as well as offering enhanced performance in alarm/timer and power management applications.
