RTC-4574NB:B ROHS

RTC-4574NB:B ROHS is an integrated Real Time Clock (RTC) utilizing stand-alone CMOS technology with external crystal oscillator and EEPROM. This device is a RoHS compliant, low power clock providing accurate time keeping for advanced applications.

Application Field

The RTC-4574NB:B ROHS clock is 0.9V to 5.5V supply voltage, low current (1μA in battery backup mode) and incorporates an on-chip oscillator, crystal, battery charger and temperature sensor. It suits advanced applications in automotive, communications, and industrial markets.

Automotive applications that can benefit from the RTC-4574NB:B include those requiring precise, real-time and accurate clock information operations all while maintaining a low current draw. This feature makes this clock a highly efficacious choice when battery powered, or when employed in a system that must operate without fail over extended periods of time.

In communications applications, the RTC-4574NB:B RoHS clock is widely used to monitor and maintain precise time setting in access systems and wireless data transmission applications, as well as various control circuits and digital television.

The RTC-4574NB:B RoHS clock also suits a variety of industrial applications. Its low current draw and excellent temperature stability make it an attractive choice for industrial automated process control, plant maintenance, medical systems and other high-accuracy applications.

Working Principle

The RTC-4574NB:B ROHS clock works by entering data into predetermined memory areas to enable time calculations and then accessing real-time clock registers for the time output. An on-chip 4K-bit EEPROM is used to store time, calendar, and other parameters. The internal EEPROM is activated after the time/date entries are set, and the internal time is incremented every second. The RTC-4574NB:B is also free-running, so it can be programmed to output values within a range of dates and times, allowing for different kinds of external applications.

The clock utilizes an external quartz crystal or ceramic resonator to provide extremely precise timing, and an on-chip oscillator provides temperature compensation. This combination of tight accuracy and temperature stability makes the RTC-4574NB:B ROHS an ideal choice for applications needing accurate time keeping.

Conclusion

The RTC-4574NB:B ROHS clock is a very low power, highly efficient, and accurate real-time clock designed for automotive, communications and industrial applications. With its low power consumption, temperature stability and accuracy, the RTC-4574NB:B is an ideal choice for time keeping in any application.
