ADSP-21160M
The load capacitance should include the processor’s
package capacitance (C
IN). The switching frequency
includes driving the load high and then back low. Address
and data pins can drive high and low at a maximum rate of
1/(2t
CK). The write strobe can switch every cycle at a
frequency of 1/t
CK. Select pins switch at 1/(2 tCK), but selects
can switch on each cycle.
