Maxim Integrated's DS1302Z+T&R Real-Time Clock

The DS1302Z+T&R from Maxim Integrated is a versatile real-time clock (RTC) module that provides a comprehensive timekeeping solution for a wide array of applications. Designed with precision and reliability in mind, this compact integrated circuit is capable of tracking seconds, minutes, hours, days, dates, months, and years with exceptional accuracy.

One of the standout features of the DS1302Z+T&R is its trickle-charge capability, which allows the RTC to maintain its timekeeping functions even when the primary power supply is disconnected. This is achieved by connecting a small lithium coin cell battery to the RTC, ensuring that time is kept without interruption, making it an ideal choice for systems that require continuous time tracking, such as embedded systems, utility meters, and other electronic appliances.

The device operates over a wide voltage range and has a low power consumption, which is crucial for battery-powered applications. The RTC is interfaced with a microcontroller via a simple serial interface, which minimizes the pin count and simplifies the connection. The DS1302Z+T&R also features a programmable trickle charger for the backup battery, which can be set to different charging rates to accommodate various battery sizes and chemistries.

Additional features of the DS1302Z+T&R include a dual-purpose data pin that can be used to read/write a byte of data to the RTC or to access an additional 31 bytes of battery-backed static RAM. This RAM can be used to store data that needs to be preserved during power loss. The RTC also provides two programmable time-of-day alarms and a programmable square-wave output, which can be used for timing, calibration, or as an interrupt source.

The DS1302Z+T&R is available in a surface-mount package and is supplied on tape and reel (T&R), which facilitates automated assembly processes, making it an excellent choice for mass production environments. Maxim Integrated's commitment to quality ensures that the DS1302Z+T&R is a reliable and cost-effective solution for maintaining accurate time in your electronic designs.

With its combination of features, low power consumption, and ease of integration, the DS1302Z+T&R from Maxim Integrated is an ideal choice for designers looking to add reliable timekeeping functionality to their projects.
