Specifications
405GP – Power PC 405GP Embedded Processor
AMCC 51
Revision 2.01 – January 6, 2005
Data Sheet
Notes: 1. In all of the following I/O Specifications tables a timing values of “na” means “not applicable” and “dc”
means “don’t care.”
2. See “Test Conditions” on page 46 for output capacitive loading.
I/O Specifications—All speeds (Part 1 of 2)
Notes:
1. PCI timings are for operation up to 66.66MHz. PCI output hold time requirement is 1ns for 66.66MHz and 2ns for 33.33MHz.
In synchronous mode, timing is relative to SysClk. In asynchronous mode, timing is relative to PCIClk.
2. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard.
3. For PCI, I/O H is specified at 0.9OV
DD
and I/O L is specified at 0.1OV
DD
. For all other interfaces, I/O H is specified at 2.4 V
and I/O L is specified at 0.4 V.
