The Maxim Integrated DS1302S+T is a versatile, low-power real-time clock (RTC) module that provides a comprehensive timekeeping solution for a wide range of applications. This compact and highly reliable component is designed to maintain accurate time and date information, from seconds to years, with minimal power consumption, making it ideal for embedded systems, consumer electronics, and portable devices.
Featuring a simple serial interface, the DS1302S+T allows for easy communication with microcontrollers and other digital systems. Its trickle-charge capability ensures that the clock continues to run even when the primary power source is unavailable, by charging a backup battery or supercapacitor. This ensures that timekeeping is maintained without interruption, which is critical for applications that require consistent time tracking, such as data loggers and alarm systems.
The DS1302S+T offers a wide operating voltage range from 2.0V to 5.5V, which provides flexibility for use in systems with varying power requirements. Additionally, its low power consumption makes it an excellent choice for battery-powered devices. The device also includes a programmable trickle charger for VCC1, which can be set with a single external resistor, allowing designers to customize the charging scheme for their specific application.
The module is equipped with 31 bytes of battery-backed static RAM, which provides additional storage for critical data that must be preserved during power loss. The clock/calendar functionality of the DS1302S+T includes seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation valid up to the year 2100.
The DS1302S+T is available in a surface-mount package and is fully operational in the industrial temperature range of -40°C to +85°C, making it suitable for harsh environments. Its compact size and robust feature set make the Maxim Integrated DS1302S+T an excellent choice for designers seeking a reliable and efficient real-time clock module for their next project.
