DRAFT
Switching Characteristics over Commercial and Industrial Operating Ranges
PSRAM Read Cycle (25 MHz and 33 MHz)
Notes:
All timing parameters are measured at V
CC
/2 with 50 pF loading on CLKOUTA, unless otherwise noted. All
output test conditions are with C
L
=50 pF For switching tests, V
IL
=0.3 V and V
IH
=V
CC
–0.3 V.
a
Testing is performed with equal loading on referenced pins.
b
If either spec 2 or spec 59 is met with respect to data hold time, the part will function correctly.
