Detailed IDD7
The detailed timings are shown below for IDD7. Changes will be required if timing parameter changes are made to the
specification.
Legend: A = Active; RA = Read with Autoprecharge; D = Deselect
IDD7: Operating Current: All Bank Interleave Read operation
All banks are being interleaved at minimum ^tRC(IDD) without violating ^tRRD(IDD) using a burst length of 4. Control
and address bus inputs are STABLE during DESELECTs. IOUT = 0mA
