ZHCSIG4A July 2018 – June 2019 DLPC3434
Although the DLPC3434 requires an array of power supply voltages, (for example, VDD, VDDLP12, VDD_PLLM/D, VCC18, VCC_FLSH, VCC_INTF), since VDDLP12 is tied to the 1.1-V VDD supply, then there are no restrictions regarding the relative order of power supply sequencing to avoid damaging the DLPC3434 (This is true for both power-up and power-down scenarios). Similarly, there is no minimum time between powering-up or powering-down the different supplies if VDDLP12 is tied to the 1.1-V VDD supply.
Although there is no risk of damaging the DLPC3434 if the above power sequencing rules are followed, the following additional power sequencing recommendations must be considered to ensure proper system operation.
Note that when VDD core power is applied, but I/O power is not applied, additional leakage current may be drawn. This added leakage does not affect normal DLPC3434 operation or reliability.
