Maxim Integrated DS1302ZN+ Real-Time Clock (RTC)

The DS1302ZN+ from Maxim Integrated is a versatile, low-power real-time clock (RTC) module that provides a full binary-coded decimal (BCD) clock/calendar with 31 bytes of static random access memory (SRAM). This integrated circuit is designed to provide precise time and date tracking, and it is particularly suitable for applications requiring long-term battery operation due to its minimal power consumption.

The DS1302ZN+ incorporates a simple serial interface for communication with a microcontroller. This interface is compatible with many types of microprocessors, and it allows for seamless integration into a variety of systems. The RTC operates on a very low power, which makes it an ideal choice for portable devices, as it can be powered by a small lithium coin cell for years without the need for replacement.

One of the key features of the DS1302ZN+ is its trickle-charge capability, which enables the device to charge a rechargeable battery or supercapacitor, ensuring that the timekeeping function continues even when the primary power source is unavailable. This feature makes it an excellent choice for systems that require a backup power source to maintain timekeeping during power interruptions.

The device supports a wide range of functions, including seconds, minutes, hours, day, date, month, and year, with automatic leap year compensation valid up to the year 2100. The clock operates in either 24-hour or 12-hour format with an AM/PM indicator, catering to various user preferences and international standards.

Enclosed in an 8-pin DIP (Dual In-line Package) or SO (Small Outline) package, the DS1302ZN+ is easy to incorporate into printed circuit boards and is designed for straightforward mounting and soldering. Its compact form factor and robust design make it a reliable choice for many applications, including embedded systems, consumer electronics, industrial controllers, and data loggers.

Overall, the Maxim Integrated DS1302ZN+ RTC offers a reliable and cost-effective solution for timekeeping in electronic systems, combining high functionality with ease of use and low power consumption.
