Introduction

M41ST95WMX6 is a real-time clock that offers high accuracy and low power consumption in a single integrated circuit. It is designed to meet the requirements of industrial-grade applications and can be used in critical applications, such as automotive, HVAC and other industrial automation applications. It is widely used in the clock/timing category of applications, as it provides reliable and accurate time synchronization for control and measurement applications.

M41ST95WMX6 Application Field

M41ST95WMX6 is among the most widely used real-time clocks for applications that manage time precisely. Its application fields are mainly:

• System power supply management;
• Alarm systems;
• Digital instrumentation;
• Electronic payment systems;
• Medical products;
• Industrial control/automation;
• Distributed control systems;
• Test and measurement devices;
• Data logging.

Its low power consumption makes it one of the most suitable real-time clocks for power switch-over applications, such as automatic load sharing systems, to ensure a seamless transition between power sources. It can also be used as the timing reference in digital audio, communications and medical equipment, to ensure synchronization and accuracy in the timing signals.

M41ST95WMX6 Working Principle

M41ST95WMX6 is based on an advanced timekeeping circuit that provides unparalleled accuracy and low power consumption. It consists of a quartz-based oscillator circuit, a display counter, an alarm comparator and an alarm reset circuit. The quartz crystal oscillator maintains an accuracy of +/- 2 ppm over its entire operating temperature range and is capable of providing a frequency accuracy within +/- 30 ppm, which makes it suitable for use in most critical clock applications.

The quartz crystal oscillator is the heart of the timer circuit. It is the component that is used to drive the time counting circuits. When power is applied to the M41ST95WMX6, the quartz crystal oscillator starts oscillating and serves as a clock source for the timer. The time counting circuit then starts counting based on the frequency of the oscillator. The time base can be adjusted to a particular frequency, and when combined with the register increments, it can provide a more accurate time.

The alarm comparator is a voltage-to-time comparator that is used to create an alarm output. The alarm comparator compares the preset alarm register values with the real-time clock register values and outputs an alarm signal when a match is found. The alarm reset circuit is responsible for resetting the alarm output after it is triggered and enables the timer to return to its original state.

M41ST95WMX6 is one of the most reliable and accurate real-time clocks and can be used in critical clock/timing applications. It provides accurate and low power consumption, making it ideal for power switch-over and synchronization applications.
