10.5. AC Parameters
10.5.1. 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.

Table 34. gives the maximum applicable load capacitance for Port 0, Port 1, 2 and 3, and ALE and PSEN signals.
Timings will be guaranteed if these capacitances are respected. Higher capacitance values can be used, but timings
will then be degraded.
Table 34. Load Capacitance versus speed range, in pF
Table 36., Table 39. and Table 42. give the description of each AC symbols.
Table 37., Table 40. and Table 43. give for each range the AC parameter.
Table 38., Table 41. and Table 44. 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. Values of the frequency must be limited to the corresponding speed grade:
Table 35. Max frequency for derating formula regarding the speed grade
Example:

x= 22 (Table 38.)
T= 50ns
