The DS1340U-18 can be used for a wide range of timing applications, from machine automation to building automation, from automotive to healthcare. In any application requiring two-wire bus communications, the DS1340U-18 can be used to support precise timekeeping. It is also suitable for circuit boards with multiple I2C slaves.
The DS1340U-18 is designed to operate in extreme temperatures and harsh environments. It is capable of operating within a range of -40°C - +85°C and is rated for up to 2000m altitude. It is resistant to vibration, shock, and humidity. The device also meets the safety requirements of various automotive and industrial standards.
Application Fields: The DS1340U-18 RTC is a highly versatile device that can be used in a variety of settings, from machine automation to healthcare. It can be used for car alarms, security systems, access control, building automation, HVAC control, water metering, refrigeration control, environmental monitoring and other industrial and consumer applications.
Working Principle: The DS1340U-18 contains three key components: the Real-Time Clock (RTC) circuit, the Chronometer (also known as the Calendar or Timer) circuit, and the Temperature sensor circuit. The RTC circuit is responsible for keeping track of the time, while the Chronometer circuit is responsible for keeping track of the calendar information such as day, month, and year. The Temperature Sensor circuit can provide temperature readings.
The RTC is a quartz crystal oscillator circuit that is used to generate an accurate frequency for timekeeping. This frequency is then used to wake up the RTC from low-power standby mode and update the internal timer registers. The Chronometer circuit uses the output of the oscillator to accurately measure time and update the calendar information, including day, month, and year. The temperature sensor measures the actual temperature and provides data to the system for climate control or other temperature related applications.
The overall timekeeping accuracy of the DS1340U-18 is ±2ppm (parts per million), with a maximum aging rate of ±2ppm per month. The RTC maintains date information for up to 59 digits of accuracy. The chronometer is accurate to the second, and the temperature readings have a resolution of 0.5°C across a -40°C to +85°C range.
The DS1340U-18 is a reliable and cost-effective solution for real-time clock applications. It is easy to integrate into design projects, and provides accurate and reliable data for a variety of timing applications.
