The DS1211 is an integrated circuit (IC) component designed by Maxim Integrated. It is a nonvolatile controller that provides functions for data logging in various applications. Here is an overview and key features of the DS1211:
1. Nonvolatile Data Storage: The DS1211 offers nonvolatile storage, allowing data to be retained even when the power is removed. This feature ensures data integrity and eliminates the risk of losing information during power disruptions.
2. Real-Time Clock: The IC incorporates a real-time clock (RTC) with an onboard crystal oscillator. The RTC provides accurate timekeeping, making it suitable for applications requiring time stamps or scheduled events.
3. Intelligent Control: The DS1211 includes programmable control features that allow users to set alarm thresholds, timing intervals, and various parameters. These controls enable customized operation and integration in specific application requirements.
4. Secure Data Storage: To prevent unauthorized access or tampering of data, the DS1211 provides a security bit feature. This security bit must be set before data can be modified, ensuring data integrity and enhancing overall system security.
5. Protection Against Power Loss: The IC offers hardware protection against power loss during write operations. This feature safeguards data by preventing corruption when sudden power failures occur.
6. Single Supply Voltage: The DS1211 operates on a single power supply voltage ranging from 4.5V to 5.5V. This characteristic simplifies the overall system design and reduces the need for additional power circuitry
