Power Sequencing for nvSRAM - KBA204197
Is there any power sequencing requirements on the VCC (core voltage) and VCCQ (I/O voltage) supplies for nvSRAM parts with dual power supplies? Can VCCQ be 0 V when VCC is present?
There is no specific power sequencing requirement to operate the nvSRAM. So, you can apply VCC and VCCQ in any order. VCCQ can be 0 V when VCC is present.
