P1-P3P4-P6P7-P9P10-P10
CY7C128A
Document #: 38-05028 Rev. ** Page 4 of 10
Switching Waveforms
Read Cycle No. 1
[10, 11]
Read Cycle No. 2
[10, 12]
Write Cycle No. 1 (WE Controlled)
[9, ]
Notes:
10. WE
is HIGH for read cycle.
11. Device is continuously selected. OE
, CE = V
IL
.
12. Address valid prior to or coincident with CE
transition LOW.
13. Data I/O pins enter high-impedance state, as shown, when OE
is held LOW during write.

Write Cycle No. 2 (CE
Controlled)
[9, 13, 14]
Notes:
14. If CE
goes HIGH simultaneously with WE HIGH, the output remains in a high-impedance state.
