Real Time Clocks (RTC) are essential elements of modern electronics systems. The RX8900CE series of Real Time Clocks from Epson are a range of highly reliable and accurate clocks used in a range of time critical applications. This article looks at the features of the RX8900CE and provides an overview of its potential application fields, as well as its working principle.

The Epson RX8900CE is a self-contained crystal oscillator that uses quartz crystal as its clock source. The RX8900CE clocks are manufactured using advanced automated process flow and integrated circuit technology, and offer an accuracy of ±2.5ppm over the full -40°C to +85°C temperature range. The series is also optimized for minimum power consumption, ensuring extended battery life and higher clock accuracy.

The Epson RX8900CE series offers an array of features and functions to meet a wide range of real-time clock applications. The clock supports both 3- and 5-volt signaling and provides on-chip battery backup input that supports up to three different voltage levels. It has an integrated battery-backed ‘keep-alive’ register, allowing it to retain time and date across power-ups and power-downs. By combining user-programmable output pins with a variety of time and alarm counting modes, the RX8900CE can be used for a broad range of real-time events, from triggering alarms to recognizing the passage of specific time intervals.

The RX8900CE series is widely used in a variety of time-sensitive applications such as time, date, and event tracking, limiting elapsed time, and synchronizing with frequency standards. In telecommunications systems, the RX8900CE is used as a master clock for precise timing network nodes and connections, while in aviation it is used to control navigation, communication and aircraft engines. It is also used in various industrial automation and home appliance applications, including thermostats, air conditioners, and printers.

The working principle behind the RX8900CE series of Real Time Clocks is based on the quartz crystal oscillator. The oscillator output is divided into two thermally compensated signals, which are synchronized with an external crystal. By combining these signals, and then comparing them with the control logic circuits, an internal time interval is calculated.

The clock circuit then calculates the number of internal cycles corresponding to 24 hours and is continuously updated to achieve the highest accuracy. When the count reaches a certain point, it is compared to the external crystal frequency and the clock is reset if needed. This cycle is repeated continuously, ensuring that the RX8900CE is accurate to the highest possible precision.

In summary, the Epson RX8900CE series of Real Time Clocks is a highly reliable and accurate range of clocks used in a wide range of time-critical applications. Its features and functions offer the flexibility needed for many time-sensitive applications, and its unique working principle ensures that the clock can achieve the highest level of accuracy. The RX8900CE is a reliable and cost-effective solution for a variety of time-related applications.
