Introduction

Programmable timers and oscillators are clocks or timing devices that are designed to produce output signals at specific intervals. Among these devices, IS82C54-1096 is a series of 8-bit programmable timer/counter chips manufactured by Philips Semiconductors. As an essential component in various forms of electronic equipment, IS82C54-1096 is widely used in many applications ranging from industry automation, military systems to consumer electronics.

Application Field

The IS82C54-1096 series provides high flexibility, accuracy and reliability. This makes it suitable for many applications such as:

Industry Automation

The IS82C54-1096 series is widely used in industrial automation for its high precision, which enables accuracy of a few microseconds. It often serves as a timer for controlling servo motors, robot arms and other industrial machinery. Moreover, it can also be used as an encoder for counting signals and monitoring motion.

Military Customized Solutions

The IS82C54-1096 series is also designed to meet the stringent requirements of military applications. It is often used in customized solutions such as missile guidance and remote control systems. Compared to conventional timer solutions, IS82C54-1096 is much more reliable and rugged.

Consumer Electronics

The IS82C54-1096 series is also popularly used in various consumer electronics products. It is often used as a time base or counter to count time in digital watches, VCRs, DVD players, and even in some audio equipment, such as CD players and speakers.

Working Principle

IS82C54-1096 is a dual-timer/counter chip that incorporates an 8-bit counter and an 8-bit timer. Both the counter and timer are controlled by an 8-bit register called clock register. A clock signal is sent to the clock register and the timer/counter is triggered when a low-to-high transition is detected.The counter decrements the 8 bit register value byte-by-byte until it reaches zero. When the counter reaches zero, it generates an output pulse and resets. This output pulse can be used to control other devices, such as motors and switches.The timer is preset with a user-defined 8 bit register value and it starts decrementing at each clock rising edge. When the timer reaches zero, it generates an output pulse and resets. This output pulse can be used to activate various circuits.

Conclusion

The IS82C54-1096 series programmable timer/counter chips are widely used in various applications due to its high reliability, accuracy and flexibility. It can be used as a timer or counter in various industrial, military, and consumer electronic applications. The timer/counter is triggered by a clock signal and it either decrements the 8 bit register value byte-by-byte for counting or starts decrementing at each clock rising edge for timing. When the timer/counter reaches zero, it generates an output pulse and resets.
