405GP – Power PC 405GP Embedded Processor

AMCC

Revision 2.03 – September 7, 2007

Data Sheet

Test Conditions

Clock timing and switching characteristics are specified in accordance with

operating conditions shown in the table “Recommended DC Operating

Conditions.” For all signals other than PCI signals, AC specifications are

characterized at OVDD = +3V and TC = +85°C with the 50pF test load

shown in the figure at right.

For PCI signals there are two different test load circuits, one for the rising

edge and one the falling edge as shown in the figures at right.

Note:

1. Maximum power is characterized at VDD = +2.7V, OVDD = +3.6V, TC = +85°C, across the silicon process (worse case to best case),

while running an application designed to maximize power consumption. The specifications at 200MHz correspond to CPU = 200 MHz,

PLB = 100MHz, OPB = EBC = 50MHz, PCI = 33.3MHz. The specifications at 266MHz correspond to CPU = 266.6MHz, PLB

=133.3MHz, OPB = EBC = 66.6MHz, and PCI = 33.3MHz.

2. AVDD should be derived from VDD using the following circuit:
