The MAX708CUA+ is a sensitive device and requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the device away from noise sources, using a solid ground plane, and minimizing trace lengths and widths.
The WDT should be disabled during power-up and power-down sequences to prevent unwanted resets. This can be done by writing to the WDT control register to disable the timer before powering down and re-enabling it after power-up is complete.
A simple RC circuit with a 10kΩ resistor and a 10µF capacitor is recommended for the reset circuitry. This provides a reliable reset signal to the device during power-up and ensures that the device is properly initialized.
The MAX708CUA+ requires a stable power supply and a valid reset signal to ensure proper operation. It is recommended to use a power-on reset (POR) circuit to ensure that the device is properly powered up and initialized before starting operation.
The internal voltage regulator of the MAX708CUA+ has a limited current capability and may not be able to supply the required current for all applications. It is recommended to use an external voltage regulator if the current requirements exceed the internal regulator's capabilities.
