405GPr – Power PC 405GPr Embedded Processor

AMCC
Revision 2.04 – September 7, 2007
Data Sheet
I/O Specifications—Group 2
Notes:
1.
The SDRAM command interface is configurable through SDRAM0_TR[LDF] to provide a 2 to 4 cycle delay before the
command is used by SDRAM.
2. SDRAM I/O timings are specified relative to a MemClkOut terminated into a lumped 10pF load.
3. SDRAM interface hold times are guaranteed at the PPC405GPr package pin. System designers must use the PPC405GPr
IBIS model (available from
www.amcc.com
) to ensure their clock distribution topology minimizes loading and reflections,
and that the relative delays on clock wiring do not exceed the delays on other SDRAM signal wiring.
4. PerClk timing is specified with a 10pF load at the package pin. The indicated timing is valid only if PerClk feedback is
selected. Refer to the
PowerPC 405GPr Embedded Processor User’s Manual
for more information.
5. Input timings are specified at 1.5V, assuming transition times between 1 and 2ns, when measured between the 10% and
90% points of the output voltage.
6. I/O H is specified at 2.4 V and I/O L is specified at 0.4 V.
