Substantive Change(s)

11/2008

• Removed voltage option of 1.10 V from Table 2 because it is not supported by MPC8640D or MPC8640

• Updated Table 4 and Table 5 with the new 1067/533 MHz device offering. This includes updated Power

Specifications.

• Added Section 4.4, “Platform Frequency Requirements for PCI-Express and Serial RapidIO”

• Updated Section 6, “DDR and DDR2 SDRAM” to include 533 MHz.

• Added core frequency of 1067 to Table 63, Table 64, Table 65 and Table 66

• Changed Max Memory clock frequency from 250 MHz to 266 MHz in Table 64

• Changed Max MPX/Platform clock Frequency from 500 MHz to 533 MHz in Table 65

• Changed Max Local Bus clock speed from 1 MHz to 133 MHz in Table 66

• Added MPX:Sysclk Ratio of 8:1 to Table 67

• Added Core:MPX Ratio of 3:1 to Table 68

• Updated Table 69 to include 533 MPX clock frequency

• Changed the Extended Temp range part numbering ‘w’ to be T instead of an H in Table 73

• Changed the DDR speed part numbering N to stand for 533 MHz intead of 500 MHz in Table 73

• Removed the statement “Note that core processor speed of 1500 MHz is only available for the

MPC8640D (dual core)” from Note 2 in Table 73 because MPC8640D is not offered at 1500 MHz core.

• Removed the part offering MC8640Dwxx1000NC which is replaced with MC8640Dwxx1067NC and

removed MC8640wxx1000NC replaced with MC8640wxx1067NC in Table 74

• Added Note 8 to Figure 57 and Figure 58.
