Document Number: MPC755ECS03AD Freescale Semiconductor Rev. 0.1, 02/2006 Advance Information MPC755 RISC Microprocessor Hardware Specifications Addendum for the XPC755xxxnnnLE Series This document describes part-number-specific changes to Freescale Part Numbers Affected: recommended operating conditions and revised electrical XPC755BRX400LE specifications, as applicable, from those described in the XPC755BPX400LE general MPC755 RISC Microprocessor Hardware XPC755CRX450LE Specifications (MPC755EC). The MPC755 and MPC745 are reduced instruction set computing (RISC) microprocessors that implement the PowerPC instruction set architecture. 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 Freescale 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. 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. This document contains information on a new product.

These devices are no longer in production. XPC755BPX400LE XPC755CRX450LE 450 Note: The X prefix in a Freescale PowerPC part number designates a Pilot Production Prototype as defined by Freescale 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. 4.1 DC Electrical Characteristics 1 Table 3.
