CDP68HC68T Series Real Time Clocks are real time clock devices that integrate a time-keeping circuit with a 32-bit counter, and a crystal-controlled oscillator circuit into a single chip. The CDP68HC68T Series Real Time Clocks are available in various packages offering different power supply voltages and operating temperatures, making them suitable for almost any application.

The primary function of CDP68HC68T Real Time Clocks is to accurately measure time. In the simplest applications, this involves counting seconds, minutes, hours, days and months, and regulating the operation of digital devices accordingly. In more complex applications, it may include taking into account leap years and other factors that may affect the accuracy of the time.

The CDP68HC68T series works by using an external crystal oscillator to measure a precise reference frequency. The frequency, usually 64 Hz or 32 kHz, is used as the clock input for the counter circuit, which counts the successive clock pulses and keeps the time. This ensures accuracy, regardless of how fast the crystal oscillator would operate.

In terms of applications, the CDP68HC68T series real time clocks have a wide variety of uses. They can be used to measure time in industrial equipment, automotive systems, communications systems and consumer electronics. In data logging, they can be used to record time and date on data taking operations. In automotive applications, they can be used to ensure that the car starts when the driver presses the start button.

The CDP68HC68T real time clock is also designed for low power operation, which means it can be used in battery operated devices such as laptops, PDAs and mobile phones. The CDP68HC68T series can also be used in applications that have low power requirements, such as watches or other wearable devices.

The CDP68HC68T real time clock is unique in that it is a CMOS chip, which means it can directly drive analog and digital ICs, DRAM and EPROM memory devices, and LCD drivers. This makes the CDP68HC68T an ideal choice for many applications.

In conclusion, the CDP68HC68T series real time clocks offer users a wide range of applications and power efficiency. This makes them ideal for almost any timing application, from automotive systems to industrial equipment, from data logging to consumer electronics. The CDP68HC68T series real time clocks provide users with accurate and reliable timekeeping, regardless of the application.
