Programmable timers and oscillators are controlling components that determine the timing of sequences and control signals within a system. The 8N4DV85FC-0077CDI8 is a device that combines these functions and is widely used in a variety of application fields. This article will discuss its potential application areas, its features, and its working principle.

Technical Specifications and Features

The 8N4DV85FC-0077CDI8 programmable timer and oscillator is an advanced device in the clock and timing category. It operates from 1.5V to 5V single supply voltage, allowing it to be used in a wide variety of environment and applications. It is also packed with a range of features. It includes a programmable edge-triggered counter, a programmable reset-on-expire timer, a divide-by-N/2 frequency divider, and a 0/1/H logic output.

Its programmable edge-triggered counter provides a linear count up of 6-bits per edge, with a programmable single stage or dual stage prescaler. This enables the timer to re-trigger automatically at preset intervals. The frequency divider allows the counter to be divided by 2 or 4, and the 0/1/H logic output provides further flexibility in timing and control.

Application Areas

The 8N4DV85FC-0077CDI8 programmable timer and oscillator is ideally suited for applications such as motor control, audio and video processing, speech coding and decoding, digital clock control and timing, and other medium to high frequency applications. Its ability to provide precise timing and control makes it suitable for tasks such as voice recognition and speech coding and decoding, as well as for applications in the automotive, medical, and telecommunications industries.

For example, in the automotive industry, it can be used in applications such as airbag deployment, dashboard display, and automatic braking. In the medical industry, it can be used to control X-ray examination timing and patient monitoring, as well as other medical monitoring tasks. In the telecommunications industry, it can be used in applications such as transmission timing and channel selection.

Working Principle

The 8N4DV85FC-0077CDI8 programmable timer and oscillator works by combining a programmable edge-triggered counter, a programmable reset-on-expire timer, a divide-by-N/2 frequency divider, and a 0/1/H logic output.

The edge-triggered counter is triggered by an external signal, typically a clock, and then counts up in response to edges of the signal. The reset-on-expire timer allows the timer to reset itself to a specified value after a set number of count-up cycles, enabling the timer to re-trigger automatically at preset intervals.

The frequency divider allows the count-up to be divided by 2 or 4, and the logic output provides further control and flexibility. This allows for precise timing, enabling the 8N4DV85FC-0077CDI8 to be used in a wide range of applications.

Conclusion

The 8N4DV85FC-0077CDI8 programmable timer and oscillator is an advanced device well-suited for both low and medium to high frequency applications. It combines a range of features to enable precise timing, control, and flexibility. It is ideal for automotive, medical, and telecommunications applications, as well as tasks such as speech coding and decoding, digital clock control, and motor control.
