Maxim Integrated DS1302ZN+TR Real-Time Clock

The Maxim Integrated DS1302ZN+TR is a highly versatile, low-power real-time clock (RTC) module that provides a comprehensive timekeeping solution for a wide array of applications. It is specifically designed to maintain accurate time and date information, ranging from seconds to years, with minimal power consumption. This makes it an ideal component for embedded systems where maintaining accurate time is crucial, and power resources are limited.

One of the key features of the DS1302ZN+TR is its trickle-charge capability, which allows the device to be powered by a small lithium battery or a supercapacitor, ensuring that timekeeping continues even when the main power supply is unavailable. This ensures that devices like data loggers, alarm systems, and personal electronics maintain accurate time without interruption.

The DS1302ZN+TR communicates with a microcontroller via a simple serial interface. This interface is compatible with many types of microcontrollers, providing flexibility in system design. The device also features a dual-purpose data pin that can be used for either data input/output or as a 32.768 kHz output pin, providing a clock signal for external use.

Robust in design, the DS1302ZN+TR comes in a compact 8-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for space-constrained applications. It operates over a wide voltage range of 2.0V to 5.5V and can function within a temperature range of -40°C to +85°C, ensuring reliability across various operating conditions.

Additional functionalities of the DS1302ZN+TR include a programmable trickle charger for the backup power supply, a simple 3-wire interface, and less than 1μA of current consumption when operating in battery-backup mode. Its full calendar functionality with seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation valid up to the year 2100, makes it a comprehensive timekeeping solution that is ready to integrate into your next project.

Whether you are designing consumer electronics, industrial control systems, or portable medical devices, the Maxim Integrated DS1302ZN+TR real-time clock offers a reliable, power-efficient way to keep track of time in your application.
