7.4 AC Parameters
7.4.1 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.
T
A
= 0 to +70

C; V
SS
= 0 V; V
CC
= 5 V
±
10%; -M and -V ranges.
T

CC

= 0 to +70

C; V
SS
= 0 V; 2.7 V < V
CC <
5.5 V; -L range.

C to +85

C; V
SS
= 0 V; 2.7 V < V
CC <
5.5 V; -L range.
(Load Capacitance for port 0, ALE and PSEN = 100 pF; Load Capacitance for all other outputs = 80 pF.)
Table 16., Table 19. and Table 22. give the description of each AC symbols.
Table 17., Table 20. and Table 23. give for each range the AC parameter.
Table 18., Table 21. and Table 24. give the frequency derating formula of the AC parameter. To calculate each
AC symbols, take the x value corresponding to the speed grade you need (-M, -V or -L) and replace this value
in the formula.
Example:
T
LLIV
in X2 mode for a -V part at 25 MHz:
x= 22
T= 40ns
T
LLIV
= 2T - x = 2 x 40 - 22 = 58ns
