• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

all device banks are idle and no bursts are in progress,
and the controller must wait the specified time before
initiating any subsequent operation. Violating either
of these requirements could result in unspecified oper-
ation.
Output Drive Strength
specified to be SSTL2, Class II. The x16 DDR SDRAM
devices used in these modules support an option for
reduced drive. The reduced drive option is intended
for lighter load and point-to-point environments. For
detailed information on output drive strength options,
refer to 256Mb or 512Mb DDR SDRAM component
data sheets.
DLL Enable/Disable
DLL enable is required during power-up initialization
and upon returning to normal operation after having
disabled the DLL for the purpose of debug or evalua-
tion. (When the device exits self refresh mode, the DLL
is enabled automatically.) Any time the DLL is enabled,
200 clock cycles at CKE HIGH must occur before a
READ command can be issued.
