PPC405CR – PowerPC 405CR Embedded Processor
Revision 1.02 – January 11, 2005
Data Sheet
AMCC
37
Table 14. I/O Specifications—133 and 200MHz
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 PPC405CR package pin. System designers must use the PPC405CR
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 rising edge at package pin with a 10pF load trails the internal PLB clock by approximately 0.8ns.
5. I/O H is specified at 2.4 V and I/O L is specified at 0.4 V.
