AC CHARACTERISTICS—ALTERNATE CE CONTROLLED WRITES
Write/Erase/Program Operations
Notes:
1. Rise/Fall
10 ns.
2. Maximum specification not needed due to the internal stop timer that will stop any erase or write operation that exceed the
device specification.
3. Card Enable Controlled Programming:
Flash Programming is controlled by the valid combination of the Card Enable (CE1, CE2) and Write Enable (WE) signals. For
systems that use the Card Enable signal(s) to define the write pulse width, all Setup, Hold, and inactive Write Enable timing
should be measured relative to the Card Enable signal(s).
4. Embedded Program Operation of 8
μ
s consist of 6
μ
s program pulse and 2
μ
s write recovery before read. This is the minimum
time for one pass through the programming algorithm. D5 = “1” only after a byte takes longer than 2 ms to Write.
