Electrical characteristics

4.3.1

Power domains and power up/down sequencing

The following table shows the constraints and relationships for the different power domains.

Supply1 (on rows) can exceed Supply2 (on columns), only if the cell at the given row and

column is reporting ‘ok’. This limitation is valid during power-up and power-down phases, as

well as during normal device operation.

During power-up, all functional terminals are maintained in a known state as described in

the device pinout Microsoft Excel file attached to the IO_Definition document.
