NOTES:
1. Transition is measured 0mV fromLow or High-impedance voltage with Output Test Load (Figure 2). This parameter is guaranteed by device characterization but
is not production tested.
2. PLCC, TQFP and STQFP packages only.
3. For MASTER/SLAVE combination, t
WC
= t
BAA
+ t
WP
, since R/
W
= V
IL
must occur after t
BAA.
4. If
OE
is LOW during a R/
W
controlled write cycle, the write pulse width must be the larger of t
WP
or (t
WZ
+ t
DW
) to allow the I/O drivers to turn off data
to be placed on the bus for the required t
DW
. If
OE
is HIGH during a R/W controlled write cycle, this requirement does not apply and the write pulse
can be as short as the specified t
WP
.
5. 'X' in part numbers indicates power rating (SA or LA).
