Explanation of the AC Symbol
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 :
TAVLL = Time for Address Valid to ALE low.
TLLPL = Time for ALE low to PSEN low.
A : Address.
C : Clock.
D : Input data.
H : Logic level HIGH
I : Instruction (program memory contents).
L : Logic level LOW, or ALE.
P : PSEN.
Q : Output data.
R : READ signal.
T : Time.
V : Valid.
W : WRITE signal.
X : No longer a valid logic level.
Z : Float.
AC Parameters
TA= 0 to + 70°C ; Vss= 0 V ; Vcc= 5 V ± 10 % ; F= 0 to 44 MHz
TA= 0 to +70°C ; Vss= 0 V ; 2.7 V <Vcc < 5.5 V ; F= 0 to 16 MHz
TA=–40° to +85°C; Vss= 0 V; 2.7 V<Vcc <5.5 V ; F= 0 to 16 MHz
TA= –55° + 125°C; Vss= 0 V; Vcc= 5 V ± 10 % ; F= 0 to 40 MHz
(Load Capacitance for PORT 0, ALE and PSEN = 100 pF ; Load
Capacitance for all other outputs = 80 pF)
