NOTES:

1. The SA56004X is optimized for 3.3 VDD operation.

2. Definition of Under Voltage Lockout (UVL): The value of VDD below which the internal A/D converter is disabled. This is designed to be a

minimum of 200 mV above the power-on-reset. During the time that it is disabled, the temperature that is in the “read temperature registers”

will remain at the value that it was before the A/D was disabled. This is done to eliminate the possibility of reading unexpected false

temperatures due to the A/D converter not working correctly due to low voltage. In case of power-up (rising VDD), the reading that is stored

in the “read temperature registers” will be the default value of 0 °C. VDD will rise to the value of the UVL, at which point the A/D will function

correctly and the normal temperature will be read.

3. VDD (rising edge) voltage below which the A/D converter is disabled.

4. VDD (falling edge) voltage below which the logic is reset.
