Write Cycle No.1: R/W Controlled Timing
[41, 42, 43, 44, 45, 46]
Write Cycle No. 2: CE Controlled Timing
[41, 42, 43, 48]
Notes:
43.t
is measured from the earlier of CE or R/W or (SEM or R/W) going HIGH at the end of write cycle.
44.If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of t
or (t
+ t
) to allow the I/O drivers to turn off and data to
be placed on the bus for the required t
SD
. If OE is HIGH during an R/W controlled write cycle, this requirement does not apply and the write pulse can be as short
as the specified t
.
45.To access RAM, CE = V
, SEM = V
.
46.To access upper byte, CE = V
IL
, UB = V
IL
, SEM = V
IH
.
To access lower byte, CE = V
, LB = V
, SEM = V
.
47.Transition is measured
±
0 mV from steady state with a 5-pF load (including scope and jig). This parameter is sampled and not 100% tested.
48.During this period, the I/O pins are in the output state, and input signals must not be applied.
