The ISL12082IUZ-T is a highly precise digital real-time clock (RT), designed specifically for low-power, high-accuracy time keeping applications. It provides a read-only time and date registers which contain the year, month, day, hour, minutes, seconds, and weekday data. The device also has a watchdog timer, and a storage area for user-defined data. The ISL12082IUZ-T is designed for applications requiring low power consumption with an extensive operating range of -40ºC to +85ºC.

Features

• Low power consumption – As low as 30uA in standby mode
• High accuracy – 0.25ppm
• High reliability – Operating temperature and voltage range: -40ºC to +85ºC and 2.3V to 5.5V
• Watchdog timer – Can be used to trigger a system reset if a program or system fails
• Relative accuracy register – Enables users to adjust the absolute accuracy of the device by programming this register
• Adjustable frequency – Programmable output interval for LED, alarm, or time stamp present
• Data storage area – 8-Byte storage area with user-defined data

Applications

The ISL12082IUZ-T is suitable for applications that require the most precise timekeeping like GPS systems, industrial controls, and HVAC systems. It is also suitable for low power applications where standby current is of utmost importance, such as serial data acquisition, portable and embedded systems. Its accuracy and low power consumption make it an ideal choice for smart metering and wireless sensors.

Working Principle

The ISL12082IUZ-T is built on an oscillator-based architecture, meaning that it utilizes a crystal oscillator as its timekeeping element. The crystal oscillator is connected to the ISL12082IUZ-T via two pins and drives the on-chip clock generator. This generator is used to control the output of the timekeeping registers, and is set to be a 40kHz frequency. The 40kHz frequency is then divided down to 1Hz to provide the time data to the timekeeping registers.

The ISL12082IUZ-T also has a watchdog timer, which can be used to trigger a system reset if a program or system fails. This timer can be set to expire after a predefined period of time, or it can be reset manually. Additionally, the relative accuracy register can be programmed to adjust the absolute accuracy of the device. This allows users to fine tune the accuracy of the ISL12082IUZ-T to meet the exact requirements of the application.

Conclusion

The ISL12082IUZ-T is an excellent choice for low power, precision timekeeping applications. Its low power consumption, high accuracy, and extended operating range make it a great choice for a wide variety of applications. It is also easy to program, making it a great choice for users needing a reliable, accurate, and low power solution.
