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/(2t
CK
), but selects
can switch on each cycle. For example, estimate P
EXT
with
the following assumptions:
A system with one bank of external data memory—asyn-
chronous RAM (16-bit)
One 64K 16 RAM chip is used with a load of 10 pF
Maximum peripheral speed HCLK = 100 MHz
External data memory writes occur every other cycle, a
rate of 1/(4t
HCLK
), with 50% of the pins switching
The bus cycle time is 100 MHz (t
HCLK
= 10 nsec)
