AC Parameters
Explanation of the AC
Symbols
Each timing symbol has 5 characters. The first character is always a “T” (stands for
time). The other characters, depending on their positions, stand for the name of a signal
or the logical status of that signal. The following is a list of all the characters and what
they stand for.
Example:T
AVLL = Time for Address Valid to ALE Low.
T
LLPL = Time for ALE Low to PSEN Low.
(Load Capacitance for port 0, ALE and PSEN = 100 pF; Load Capacitance for all other
outputs = 80 pF.)
Table 98 Table 101, and Table 104 give the description of each AC symbols.
Table 99, Table 100, Table 102 and Table 105 gives the range for each AC parameter.
Table 99, Table 100 and Table 106 give the frequency derating formula of the AC
parameter for each speed range description. To calculate each AC symbols. take the x
value in the correponding column (-M or -L) and use this value in the formula.
Example: T
LLIU for -M and 20 MHz, Standard clock.
x = 35 ns
T 50 ns
T
CCIV = 4T - x = 165 ns
