External Memory Interface Timing — CY7C53150, V
Differential Transceiver Electrical Characteristics
Notes:
15. t
16. Refer to Figure 3 for detailed measurement information.
17. The data hold parameter, t
18. Refer to Figure 6 and Figure 5 for detailed measurement information.
19. The three-state condition is when the device is not actively driving data. Refer to Figure 2 and Figure 5 for detailed measurement information.
20. To meet the timing above for 20-MHz operation, the loading on A0–A15, D0–D7, and R/W is 30 pF. Loading on E is 20 pF.
21. Common mode voltage is defined as the average value of the waveform at each input at the time switching occurs.
