MPC755XLEPNS/D Rev. 0, 2/2003 MPC755 Part Number Specification for the XPC755Bxx400LE and XPC755CRX450LE Series
Motorola Part Numbers Affected: XPC755BRX400LE XPC755BPX400LE XPC755CRX450LE
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.

Notes: 1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions is not guaranteed. 2. 2.0 V nominal.

Processor (CPU) Frequency Unit 400 MHz Full-Power Mode Typical Maximum Doze Mode Maximum Nap Mode Maximum Sleep Mode Maximum 470 Sleep Mode (PLL and DLL Disabled) Maximum 430 430 mW 1, 2 470 mW 1, 2, 4 1.0 1.0 W 1, 2, 4 2.3 2.8 W 1, 2, 4 4.0 6.0 4.6 8.0 W W 1, 3, 4 1, 2 450 MHz Notes
Notes: 1. These values apply for all valid processor bus and L2 bus ratios. The values do not include I/O supply power (OVDD and L2OVDD) or PLL/DLL supply power (AVDD and L2AVDD). OVDD and L2OVDD power is system dependent, but is typically <10% of VDD power. Worst case power consumption for AVDD = 15 mW and L2AVDD = 15 mW. 2. Maximum power is measured at nominal VDD (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 VDD (see Table 3) and 65C in a system while running a typical code sequence. 4. Not 100% tested. Characterized and periodically sampled.

Note: 1. Caution: The SYSCLK frequency and PLL_CFG[0:3] settings must be chosen such that the resulting SYSCLK (bus) frequency, CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating frequencies. Refer to the PLL_CFG[0:3] signal description in Section 1.8.1, "PLL Configuration," for valid PLL_CFG[0:3] settings.
