Timing of Power-Up Power-Down
Waveform of Read Cycles(5)
NOTES:
1. Timing depends on which signal is asserted last,
OE, CE, LB or UB.
2. Timing depends on which signal is de-asserted first
CE, OE, LB or UB.
3. tBDD delay is required only in cases where the opposite port is completing a write operation to the same address location. For simultaneous read operations
BUSY
has no relation to valid output data.
4. Start of valid data depends on which timing becomes effective last: tAOE, tACE, tAA, tABE, or tBDD.
5.
SEM = VIH.
6.
CE = L occurs when CE0 = VIL and CE1 = VIH. CE = H when CE0 = VIH and/or CE1 = VIL.
