EXPLANATION OF THE AC SYMBOLS
Each timing symbol has 5 characters. The first char-
acter 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.
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:RD signal.
T:Time.
V:Valid.
W:WR signal.
X:No longer a valid logic level.
Z:Float.
For example,
TAVLL e Time from Address Valid to ALE Low.
TLLPL e Time from ALE Low to PSEN Low.
AC CHARACTERISTICS
: (Over Operating Conditions; Load Capacitance for Port 0, ALE, and
PSEN e 100 pF; Load Capacitance for All Other Outputs e 80 pF)
EXTERNAL MEMORY CHARACTERISTICS
All parameter values apply to all devices unless otherwise indicated. In this table, 87C51/BH refers to
87C51/BH, 87C51-1/BH-1 and 87C51-2/BH-2.
