The recommended operating voltage range for the DS1816R-5+T&R is 4.5V to 5.5V.
To ensure reliable data retention, it is recommended to follow proper power-up and power-down sequences, and to avoid exposing the device to extreme temperatures or voltage fluctuations.
The maximum clock frequency supported by the DS1816R-5+T&R is 1 MHz.
While the DS1816R-5+T&R is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the device's performance and reliability may be affected, and it is recommended to consult with Maxim Integrated Products' support team for guidance.
The DS1816R-5+T&R has a built-in brownout detection circuit that resets the device when the supply voltage falls below a certain threshold. To handle brownout detection and reset, it is recommended to use an external capacitor to filter out noise and ensure a clean reset signal.
