NPe405H – PowerNP NPe405H Embedded Processor
Table 16. I/O Specifications—266MHz (Sheet 2 of 3)
Notes:
1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.
2. The SDRAM command interface is configurable through SDRAM0_TR[LDF] to provide a 2 to 4 cycle delay before the
3. SDRAM I/O timings are specified relative to a MemClkOut terminated in a lumped 10pF load.
4. SDRAM interface hold times are guaranteed at the NPe405H package pin. System designers must use the NPe405H IBIS
5. PerClk rising edge at package pin with a 10pF load trails the internal PLB clock by approximately 0.8ns.
