Preliminary Information
X1209
Write Cycle Timing
Power Up Timing
Notes:
(1) Delays are measured from the time V
CC
is stable until the specified operation can be initiated. These parameters are not 100%
tested. V
CC
slew rate should be between 0.2mV/μsec and 50mV/μsec.
(2) Typical values are for T
A
= 25°C and V
CC
= 5.0V
