8XC51FX
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/PROG 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, 8XC51FX refers to
8XC51FX, 8XC51FX-1 and 8XC51FX-2.
