• Manufacturer Part Number: ppc440epx
• Description: Powerpc 440epx Embedded Processor
• Manufacturer: Applied Micro Circuits Corporation (AMCC)

440EPx – PPC440EPx Embedded Processor
Table 20. I/O Specifications—PCI, USB, UART, IIC, SPI, Ethernet, System and Debug Interfaces (Sheet 3 of 3)
Notes:
1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.
2. SMIISync is a weak driver. Redrive SMIISync when driving more than one load.
3. TDO timing is referenced to the falling edge of TCK.
