CY7C1049B-17VC

P1-P3P4-P6P7-P9P10-P10
CY7C1049B
Document #: 38-05169 Rev. *A Page 7 of 10
Write Cycle No. 1 (CE
Controlled)
[15, 16]
Write Cycle No. 2 (WE Controlled, OE HIGH During Write)
[15, 16]
Notes:
15. Data I/O is high impedance if OE
= V
IH
.
16. If CE
goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
17. During this period the I/Os are in the output state and input signals should not be applied.
