It is assumed that all 1.15V supplies come from the same source, although some can have additional filtering before entering the DLPC7530. As such, it is expected these supplies to ramp together (aside from differences caused by filtering). This same expectation is true for the 1.21V, 1.8V, and 3.3V supplies.
The DLPC7530 has specific power supply sequencing requirements, listed below, that include the timings specified in this table.
  1. Power Up Order:
    1. 1.15V (Core, Analog) » 1.8V (I/O, SCS) » 1.21V (SCS)
    2. 1.15V (Core, Analog) » 3.3V (I/O
  2. Power Down Order:
    1. 3.3V (I/O) » 1.15V (Core, Analog)
    2. 1.21V (SCS) » 1.8V (I/O, SCS) » 1.15V (Core, Analog)
This delay requirement parameter is defined as the time between two events. The first event is the point where the 1.15V power supply ramp-up is started, and the second event is when the 1.15V supply ramp-up reaches 80% of TOV (at which point the 1.8V supply can start its ramp-up). Because the occurrence of the second event depends on the specific design of the 1.15V power supply, the designer must determine the specific delay time.
This delay requirement parameter is defined as the time between two events. The first event is the point where the 1.8V power supply ramp-up is started, and the second event is when the 1.8V supply ramp-up reaches 80% of TOV (at which point the 1.21V supply can start its ramp-up).

This delay requirement parameter is defined as the time between two events. The first event is the point where the 1.21V power supply ramp-down is started, and the second event is when the 1.21V supply ramp-down reaches 20% of TOV (at which point the 1.8V supply can start its ramp-down). Because the occurrence of the second event depends on the specific design of the 1.21V power supply, the designer must determine the specific delay time. The intent of this delay time is to determine that the voltage level of the 1.8V supply never falls lower than the voltage level of the 1.21V supply during the ramp-down until the 1.2V supply is below 300 mV.
This max value is only applicable if the 1.8V power remains ON while PWRGOOD is inactive. Otherwise, there is no maximum limit.
As long as noise on this signal is below the hysteresis threshold
This delay requirement parameter is defined as the time between two events. The first event is the point where the 3.3V power supply ramp-down is started, and the second event is when the 3.3V supply ramp-down and 1.8V supply ramp down reaches 10% of TOV (at which point the 1.15V supply can start its ramp-down). Because the occurrence of the second event depends on the specific design of the 3.3V and 1.8V power supply, the designer must determine the specific delay time.
If PROJ_ON is used for power down then Power Hold Time (tPH) is not required.
This delay requirement parameter is defined by design of RECLKA oscillator. Stable clock must be provided before releasing POSENSE.
