EBI timing specified at: V
Speed is the nominal maximum frequency. Max. speed is the maximum speed allowed including frequency modulation (FM).
82 MHz parts allow for 80 MHz system clock + 2% FM; 114 MHz parts allow for 112 MHz system clock + 2% FM; and
132 MHz parts allow for 128 MHz system clock + 2% FM.
The external bus is limited to half the speed of the internal bus.
Refer to fast pad timing in
