MPC8272
PowerQUICC II™ Family
Hardware Specifications
This hardware specification contains detailed information on
power considerations, DC/AC electrical characteristics, and
AC timing specifications for the MPC8272 family of
devices—the MPC8272, the MPC8248, the MPC8271, and
the MPC8247. These devices are .13µm (HiP7) members of
the PowerQUICC II™ family of integrated communications
processors. They include on a single chip a 32-bit
PowerPC
™
core that incorporates memory management
units (MMUs) and instruction and data caches and that
implements the PowerPC instruction set; a modified
communications processor module (CPM); and an integrated
security engine (SEC) for encryption (the MPC8272 and the
MPC8248 only).
All four devices are collectively referred to throughout this
hardware specification as ‘the MPC8272’ unless otherwise
noted.
