95V850AGLF application field and working principle

The 95V850AGLF is a compact low-power CMOS crystal-controlled real time clock/calendar (RTC), designed for use in applications requiring an accurate time-keeping device. It has been designed for easy integration into a wide range of product designs, including battery-powered systems like watches and toys, as well as automotive and handheld applications. The 95V850AGLF chip contains a crystal oscillator, a 32bit counter and MOSFETs, as well as several logic gates and comparators.

The 95V850AGLF chip is built around a highly accurate and stable quartz crystal, which is used in order to provide a steady frequency of 32,768 Hz. This allows the chip to provide high accuracy even when battery-powered. The crystal oscillator is clocked with a low power and low voltage circuit, which reduces power consumption, while the MOSFETs provide the necessary logic to read, write and update the time and date information stored in the chip’s registers.

The 95V850AGLF chip operates in two basic modes: Real-Time Mode (RTM) and Event Read/Write (ERW) mode. In RTM, the counter advances every second and drives an alarm that can be programmed in 6-bit increments. The alarm can be set to trigger at any whole minute, or a range of seconds within a minute. This allows user defined events to be synchronised with a known time. In ERW mode, the counter is stopped and registers can be read, and information written to the chip’s registers.

The 95V850AGLF chip can be used to provide timekeeping functions for a wide range of applications, including consumer electronics, automotive, medical and industrial applications, among others. It is capable of accurately measuring time intervals and setting alarms for scheduled events. Furthermore, it can interface with other external circuits, such as an LED display, enabling the user to show real-time and date information.

In summary, the 95V850AGLF chip is a highly accurate and low-power crystal-controlled real time clock/calendar which is ideal for use in a wide range of product designs. Due to its low power consumption and high accuracy, it is suitable for battery-powered applications, as well as automotive and handheld applications. Its real-time mode and event read/write mode enable user-defined events to be synchronised with a known time, while its ability to interface with external circuits allows for real-time and date information to be displayed.
