AC Waveforms for Programming Operations
ANALYSIS OF PROGRAM TIMING WAVEFORMS
Program Setup/Program
Two-cycle write commands are required for program
operations (section A and B). The first program com-
mand (40h) is a Setup command and does not affect
the array data (section A).The second program com-
mand latches address and data required for program-
ming on the falling and rising edge of WE# respectively
(section B). The rising edge of this WE# pulse (section
B) also initiates the programming pulse. The device is
programmed on a byte by byte basis either sequentially
or randomly.
The program pulse occurs in section C.
Time-Out
A software timing routine (10 μs duration) must be initi-
ated on the rising edge of the WE# pulse of section B.
Note:
An integrated stop timer prevents any possibility
of overprogramming by limiting each time-out period of
10 μs.
Program-Verify
Upon completion of the program timing routine, the mi-
croprocessor must write the program-verify command
(C0h). This command terminates the programming op-
eration on the rising edge of the WE# pulse (section D).
The program-verify command also stages the device
for data verification (section F). Another software timing
