Clock/Timing - Real Time Clocks

CDP68HC68T1M96 is a basic low-power CMOS integrated circuit that was originally developed as a low-cost, low-power alternative to the Commodore 68000 microcontroller. This cost-effective device has a wide range of applications and has since become one of the most popular real time clocks (RTC) available on the market. The CDP68HC68T1M96 is a great choice for those looking for a reliable, accurate time-keeping device for any type of project.

Features

The CDP68HC68T1M96 real time clock features an 8-bit, input/output (I/O) data bus and a 16-bit wide user addressable area in the same package. The device also incorporates an internal 8-byte static RAM and a 16-byte RAM page register, allowing the user to store data that can be read and written to at any time, regardless of whether power is supplied to the device. The CDP68HC68T1M96 also features an Onboard Crystal Oscillator, which provides accurate timing accuracy and power-management capabilities. The onboard oscillator also allows the device to enter into a super low-power state, when it\'s not actively needed, thus extending battery life of any system that it is incorporated in.

Application Fields

Due to its low cost and wide range of features, the CDP68HC68T1M96 RTC has been incorporated into a wide range of projects, from hobbyist to industrial level. The device’s small form factor and its simple interrupts and register access interfaces make it perfect for incorporating into DIY projects such as time keepers, time monitors, memory and data loggers, security mechanisms, and much more. The device is even capable of replacing the more expensive and complex microcontrollers in certain applications, making it a great choice for those looking for low-cost and reliable solution.

Working Principle

The CDP68HC68T1M96 real time clock has an onboard frequency stabilized crystal oscillator that acts as the time source. This crystal is triggered by a quartz frequency within the range of 32.768KHz. From there, the oscillator is then divided by pairs into a lower frequency and then to a 32-bit count that is used by the device in order to keep track of time and date count. The device also contains a four-bit serial port interface that allows it to be interfaced with other devices, such as those used for setting the time and memory data.

Conclusion

The CDP68HC68T1M96 real time clock is a great device to consider when looking for a low-cost, low-power clock and timer device. It offers a wide range of features that make it perfect for a variety of applications, from hobbyist, through to professional and industrial level uses. Its onboard crystal oscillator also allows for accurate timekeeping, as well as power-conserving modes for when the device is not actively needed. All in all, the CDP68HC68T1M96 is a great choice for anybody looking for a reliable, low cost, and accurate time-keeping device.
