The DS1670E is a real-time clock from Maxim Integrated that can be used in a variety of applications, ranging from consumer medical equipment to smart home devices. The DS1670E provides an excellent method to integrate clock and calendar functionality into embedded systems. The DS1670E time-keeping capabilities include up to 64 minutes of time drift correction, wide programming range for application purposes, and a longer battery life than traditional real-time clocks.
Application Fields:
- Industrial Measurements
- Home Automation
- Medical Devices
- Consumer Electronics
- Security Systems
Functions and Features:
- Integrated timekeeping capability with time drift correction
- User programmable functions and settings
- Battery backup to maintain timekeeping accuracy
- Compact PCB form factor for reduced space requirements
- Wide programming range for application specific purposes
- Longer battery life than traditional real-time clocks
Working Principle:
The DS1670E works on the principle of keeping track of the number of 32.768KHz clock cycles that have passed since the device was powered up. The device has a timekeeping register that increments every time a clock cycle has been counted. To ensure accurate timekeeping, the device has an oscillator that regularly verifies the accuracy of the timekeeping register. If the oscillator detects that the count has drifted too far, it will adjust the timekeeping register accordingly to keep it accurate.The specific data is subject to PDF, and the above content is for reference
