NOTES:
1. Chip-Enable Controlled Writes: Write operations are driven by the valid combination of CE
Y
and WE
Y
. In systems where
CE
Y
defines the write pulsewidth (within a longer WE
Y
timing waveform), all setup, hold and inactive WE
Y
times should be
measured relative to the CE
Y
waveform.
2. Sampled, not 100% tested.
3. Refer to Table 3 for valid A
IN
for byte write or block erasure.
4. Refer to Table 3 for valid D
IN
for byte write or block erasure.
5. Byte write and block erase durations are measured to completion (SR.7
e
1, RY/BY
Y
e
V
OH
). V
PP
should be held at
V
PPH
until determination of byte write/block erase success (SR.3/4/5
e
0)
6. See High Speed AC Input/Output Reference Waveforms and High Speed AC Testing Load Circuits for testing characteris-
tics.
