Explanation of the AC Symbol

Each timing symbol has 5 characters. The first character Example :

is always a “T” (stands for time). The other characters,

TAVLL = Time for Address Valid to ALE low.

TLLPL = Time for ALE low to PSEN low.

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.

A : Address.

C : Clock.

D : Input data.

Q : Output data.

R : READ signal.

T : Time.

H : Logic level HIGH

I : Instruction (program memory contents).

L : Logic level LOW, or ALE.

P : PSEN.

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 36 MHz

TA = –55° + 125°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 36 MHz

(Load Capacitance for PORT 0, ALE and PSEN = 100 pF ; Load Capacitance for all other outputs = 80 pF)
