HIGH IMPEDANCE

proper number of clock cycles to start an internal write

cycle. Access to the array during an internal write cycle

is ignored and program-ming is continued. On power up,

SO is in a high impedance.

When powering down, the supply should be taken down

to 0V, so that the CAT25C32/64 will be reset when

power is ramped back up. If this is not possible, then,

following a brown-out episode, the CAT25C32/64 can

be reset by refreshing the contents of the Status Regis-

ter (See Application Note AN10).
