Real Time Clocks (RTCs) are essential components in applications that require accurate timing. Extensive research and development has advanced the technological capabilities of RTCs to offer excellent performance, accuracy, and energy efficiency. The RX-4801JE:UB is a low-power, programmable RTC optimized to increase accuracy in timing settings, protocol compliance, and event management. This article provides an overview of the RX-4801JE:UB’s application fields and working principles.

Application Field

The RX-4801JE:UB is highly-accurate, low-power RTC designed for industrial and consumer applications which require precise timing measurements and synchronization with peripheral devices. Embedded in many designs, the RX-4801JE:UB is suitable for medical, medical device, automotive and automotive control application fields. Its optimized performance assists systems in accurately setting time and dates, counting time and monitoring and recording events.

Working Principle

The RX-4801JE:UB operates as a programmable RTC system, driven by an internal crystal oscillator. It consists of a Real-Time Clock (RTC) core and a backup battery which ensure accuracy and system protection in the event of a power failure. When power-on, the system will check the current time and date to activate the operating system. To set the time, the programming side needs to write into the control register with the desired values. The RX-4801JE:UB features an interrupt module that supports multiple modes and depth settings. The interrupt could be used to carry out time-related processes, such as waking from sleep, or starting a timer or alarm.

In terms of accuracy, the RX-4801JE:UB features a watch crystal with an accuracy of ±3ppm (parts per million). This improved accuracy increases the accuracy of timing settings and inter-device synchronization. It can also detect frequencies up to 400HZ, which is ideal for industrial applications. In terms of power management, the RX-4801JE:UB is designed to be low-power with a system power consumption of just 0.2μA at 3V. This low power requirement makes the device suitable for battery-powered applications.

Conclusion

The RX-4801JE:UB programmable RTC is optimized for accuracy and energy efficiency, making it the ideal device for industrial and consumer applications with high timing accuracy requirements. Its low power consumption and frequency detection capabilities further expand the available system applications. The RX-4801JE:UB provides an accurate and efficient timing solution for projects that require precision timing.
