CY7C199C-15PXC

P1-P3P4-P6P7-P9P10-P12P13-P13
CY7C199C
Document #: 38-05408 Rev. *C Page 7 of 13
Read Cycle No. 2
[11, 12]
Write Cycle No. 1 (WE Controlled)
[13, 14, 15]
Notes:
11. This cycle is OE
Controlled and WE is HIGH read cycle.
12. Address valid prior to or coincident with CE
transition LOW.
13. This cycle is WE
controlled, OE is HIGH during write.
14. Data In/Out is high impedance if OE
= V
IH
.
15. During this period the I/Os are in output state and input signals should not be applied.

Write Cycle No. 2 (CE Controlled)
[14, 16, 17]
Write Cycle No. 3 (WE Controlled, OE Low)
[18]
Notes:
16. This cycle is CE
controlled.
17. If CE
goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
18. The cycle is WE
controlled, OE LOW. The minimum write cycle time is the sum of t
HZWE
and t
SD
.
