The DS1302ZN is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a real-time clock (RTC) module that provides accurate timekeeping for various applications. This IC has several key features that make it suitable for use in different electronic devices.
One of the key features of the DS1302ZN is its low power consumption. It operates on a voltage supply ranging from 2.0V to 5.5V, and its power usage is minimal. This makes it ideal for battery-powered devices that require long-term timekeeping without frequent battery replacements.
The DS1302ZN also offers a simple interface for easy integration into different systems. It uses a 3-wire synchronous serial interface, allowing straightforward communication with microcontrollers or other digital circuits. This simplifies the design process and reduces the complexity of connecting the IC to the rest of the system.
Furthermore, this IC has built-in trickle charge circuitry, which maintains the backup power supply for the clock during main power failures. This ensures that the clock continues to operate accurately, even when the primary power source is unavailable. The DS1302ZN utilizes an external battery to provide backup power, enabling uninterrupted timekeeping.
Another notable feature of the DS1302ZN is its capability to track time in seconds, minutes, hours, days, dates, months, and years. It also includes an alarm function with a programmable frequency and duration
