It includes a quartz crystal oscillator, a battery back up system, temperature sensor, and two integrated resistors. It also provides a wide temperature range of -40 to +85 °C and an operating voltage range of 2 to 4.5 volts.

Application Field

The RX-4581NB:B0 ROHS has a wide application field including industrial control systems, home automation systems, telecommunications systems, networks, and multi-node systems. It is used for time synchronization and for time-critical data collection tasks. The low power consumption of this real time clock makes it ideal for applications in remote and mobile applications where power supply can be limited or in critical environments where reliable timekeeping is essential.

Working Principle

The RX-4581NB:B0 ROHS uses a quartz crystal oscillator as the main timekeeping component. The oscillator typically operates at a frequency of 32.768 kHz and is regulated by a voltage-controlled frequency calibrator (VCFC). The VCFC maintains a constant frequency by varying the capacitors within the oscillator circuit in response to changes in voltage. The oscillator also includes an integrated temperature sensor that monitors the environment to ensure reliable and accurate timekeeping.

The RX-4581NB:B0 ROHS also includes a battery back up system to ensure reliable timekeeping in the event of a power outage. The back up system features power saving circuit design which allows for extended battery life. The integrated resistors are designed to reduce EMI emissions and to provide protection from external noise or interference.

In addition to its timekeeping capabilities, the RX-4581NB:B0 ROHS also includes an internal watchdog timer which ensures reliable operations in critical systems. The watchdog timer can be used to automatically reset the system in the event of an error or malfunction thus preventing any data corruption or loss of operations.

The RX-4581NB:B0 ROHS is a reliable and cost-effective real-time clock suitable for use in a variety of applications including industrial control systems, home automation systems, telecommunications systems, and networks. Its wide temperature range and low power consumption make it ideal for use in remote and mobile applications, and its integrated temperature sensor, battery back up system, and EMI resistance provide reliable and accurate timekeeping in critical environments.
