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 ALEPROG 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 8XC51RX refers to
8XC51RX and 8XC51RX-1 8XC51RX-24 refers to 8XC51RX-20 and 8XC51RX-24
