Notes: 1. V
CC
must be applied simultaneously or before V
PP
and removed simultaneously or after V
PP
.
2. This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven—
see timing diagram.
3. Program Pulse width tolerance is 50
µsec
±
5%.
Note: 1. The AT27BV4096 has the same Product Identification Code as the AT27C4096. Both are programming compatible.
