This document describes part-number-specific changes to recommended operating conditions
and revised electrical specifications, as applicable, from those described in the general
MPC755 RISC Microprocessor Hardware Specifications
(Order No. MPC755EC/D). The
devices described in this specification are no longer in production and this document is
provided for reference only. For recommended upgrades or replacement devices, contact your
Motorola sales office.
Specifications provided in this document supersede those in the
MPC755 RISC
Microprocessor Hardware Specifications,
Rev. 6 or later, for the part numbers listed in
Table A only. Specifications not addressed herein are unchanged. Because this document is
frequently updated, refer to http://www.motorola.com/semiconductors or to your Motorola
sales office for the latest version.
Note that headings and table numbers in this document are not consecutively numbered. They
are intended to correspond to the heading or table affected in the general hardware
specification.
Part numbers addressed in this document are listed in Table A. For more detailed ordering
information, see Section 1.10, “Ordering Information.”

Note:
The X prefix in a Motorola PowerPC part number designates a “Pilot Production Prototype” as
defined by Motorola SOP 3-13. These are from a limited production volume of prototypes
manufactured, tested, and Q.A. inspected on a qualified technology to simulate normal production.
These parts have only preliminary reliability and characterization data. Before pilot production
prototypes may be shipped, written authorization from the customer must be on file in the applicable
sales office acknowledging the qualification status and the fact that product changes may still occur
while shipping pilot production prototypes.

2. Maximum power is measured at nominal V
DD
(see Table 3) while running an entirely cache-resident, contrived
sequence of instructions which keep the execution units maximally busy.
3. Typical power is an average value measured at the nominal recommended V
DD
(see Table 3) and 65°C in a system
while running a typical code sequence.
4. Not 100% tested. Characterized and periodically sampled.

Caution:
The SYSCLK frequency and PLL_CFG[0:3] settings must be chosen such that the resulting SYSCLK
