Real Time Clocks (RTCs) are typically used to track time in digital systems. Most RTCs are used in system applications where there a set of events need to take place in a timely manner. This can be accomplished by having the RTC issue an interrupt at a specific time or timing interval. The PCF2123TS/1,118 is an RTC that is commonly used in such systems.

The PCF2123TS/1,118 RTC is based on a 32 kHz crystal that provides the clock signal to two counter registers. Timing information is stored in a 32-bit register which contains seconds, minutes, hours, day, date, month and year. The counter registers can be programmed to count up or down for a variety of timing applications. Alarms can be programmed to generate interrupts at specific times.

The PCF2123TS/1,118 is an extremely accurate RTC with a maximum accuracy of +/- 25 seconds per month at 25 degrees Celsius. The clock has an internal battery for backup purposes, so it will retain the correct time and date even when the main power supply is not present.

The PCF2123TS/1,118 is used in a variety of applications including embedded systems, industrial automation, time-tracking applications and many more. In embedded systems, the PCF2123TS/1,118 is typically used in conjunction with an embedded microcontroller (MCU) to program the RTC so it can issue an interrupt at the desired time. The MCU can then take the necessary action to complete the task.

The PCF2123TS/1,118 is also used in industrial automation applications, where it can be used to control the timing of an event, such as turning an automation equipment on or off at specific times, or to track the production output at any given time. In time-tracking applications, the PCF2123TS/1,118 can be used to keep track of time spent on tasks, or to log work hours of personnel.

The PCF2123TS/1,118 can also be used in applications where low power consumption is important. It runs on 1.8V to 5V, consuming only 0.75mA of current when in active mode, and 0.2µA of current when in sleep mode. This makes it ideal for battery-powered and portable applications.

Overall, the PCF2123TS/1,118 is an extremely accurate and reliable Real Time Clock that is ideal for a wide range of applications. With its accurate timekeeping and low power consumption, it is perfect for embedded systems, industrial automation and time-tracking applications.
