SpeciÞcations
Freescale Semiconductor, Inc.
To operate at maximum bus frequency i.e 8MHz (125ns) without
WAIT States:-
Bus Frq = Memory Access(max) + CSDelay(max) + Data Setup(min)
==> Memory Access(max) = 125 - 22 -16
==> Maximum Memory Access Time = 87ns
With an external memory access time of 120ns the maximum bus
speed without WAIT States is :-
Bus Frq = Memory Access(max) + CSDelay(max) + Data Setup(min)
==> Maximum Bus Frequency = 120 + 22 + 16
==> Maximum Bus Frequency = 158ns = 6.33MHz
