AUTOMOTIVE 87C54/87C54-20
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,
T
AVLL
e
Time from Address Valid to ALE Low
T
LLPL
e
Time from ALE Low to PSEN Low
