ICM7555CN/01,112 application field and working principle

The ICM7555CN/01,112 is a programmable timer and oscillator product produced by Intersil, with a wide range of legitimate applications. It is a CMOS timer/oscillator, configured as a 16-pin dual-in-line package with the suffix "-01". It has a wide operating temperature range of -40°C to +85°C, and is built using a higher-gain, higher performance CMOS cornerstone.

The ICM7555CN/01,112 is a precision timer and oscillator that is an optimal solution for a variety of applications. It is typically used in projects that require precise timing, such as auto-updates, communications, interval timers, alarms, and clock synchronization. It can also be used for frequency synthesis, and has a wide variety of configurable parameters. The ICM7555CN/01,112 has the ability to generate precision pulse trains with accuracy to within ±2%.

Working Principle

The ICM7555CN/01,112 has a triple-gate CMOS time base that allows the device to have heightened accuracy and longer operational life. The device operates on a 7555-like timer circuit and can be operated in two modes, namely the clock mode and the count-down mode. In the clock mode, it can be used to keep time, either from its own onboard crystal oscillator or from an external clock cycling. In the count-down mode, it counts down from 9999 to 0, at a rate determined by the oscillator. This means the device is capable of functioning as a clock, but it can also be used for digital counting, delay timing, and alarm triggering purposes.

The ICM7555CN/01,112 comes with a power-on reset pin which ensures proper start-up and restarts the clock whenever power is removed. This feature also prevents the premature expiration of timers when the system is rebooted or shut down. Additionally, the device is designed to operate with a wide voltage range, from 2.5V to 12V, giving it a great degree of versatility.

Conclusion

The ICM7555CN/01,112 is a precision programmable timer and oscillator with a wide range of applications. It is designed to provide stable and accurate timing and frequency synthesis over changing temperatures and supply voltage. Furthermore, the device comes with an on-board reset pin which ensures proper start-up and prevents the premature expiration of timers. The ICM7555CN/01,112 is the perfect solution for any project that requires precise timing and count-down operations.
