NXP MC7448TVU1267ND

This document is a hardware specification addendum for the MC7448Txxnnnnmx series MPC7448, describing specific changes to the corresponding part numbers relative to the general MPC7448 RISC microprocessor hardware specification, including applicable changes to recommended operating conditions and revised electrical specifications. The MPC7448 is a PowerPC™ microprocessor built on Power Architecture™ technology. The specifications provided in this document apply only to the part numbers listed herein, superseding the corresponding specifications in revision 3 or later of the MPC7448 RISC Microprocessor Hardware Specifications; specifications not mentioned in this document remain unchanged. The headings and table numbers in this document are not sequentially numbered, and are used to correspond to the affected headings or tables in the general hardware specification. Freescale part numbers with a "P" prefix represent pre-production prototypes with only preliminary reliability and characterization data; shipment of pre-production prototypes requires a written authorization on file at the applicable sales office, acknowledging the qualification status of the device and that the product is still subject to change. Freescale grades devices by both power dissipation and core frequency; power limits for each speed grade are independent of one another, and each device is tested only at its maximum core frequency. Deep Sleep mode power dissipation is independent of clock frequency; devices support operation below the rated maximum frequency, and devices operating below the rated maximum frequency will dissipate less power as long as the clock frequency meets specification requirements; power dissipation of a given device must not be extrapolated from the power specifications of a lower speed grade. Subject to the maximum core frequency constraint, VDD and AVDD may be reduced to decrease power dissipation.

• VDD and AVDD can be reduced to lower power consumption, subject to maximum core frequency constraints
• Voltage derating supported on select speed grades
• Operation below rated maximum core frequency supported
• Deep Sleep mode power consumption independent of clock frequency
