about power considerations, DC/AC electrical characteristics, AC
timing specifications, and pertinent electrical and physical
characteristics of the MPC852T. For information about functional
characteristics of the processor, refer to the MPC866
PowerQUICC Family Users Manual (MPC866UM). The
TM
MPC852T contains a PowerPC processor core.
1 Overview
The MPC852T PowerQUICC is a 0.18-micron derivative of
TM
the MPC860 PowerQUICC family, and can operate up to 100
MHz on the MPC8xx core with a 66-MHz external bus. The
MPC852T has a 1.8 V core and a 3.3 V I/O operation with 5-V
TTL compatibility. The MPC852T integrated communications
controller is a versatile one-chip integrated microprocessor and
peripheral combination that can be used in a variety of controller
applications. It particularly excels in Ethernet control applications,
including CPE equipment, Ethernet routers and hubs, VoIP clients,
and WiFi access points.
The MPC852T is a PowerPC architecture-based derivative of the
Motorola MPC860 Quad Integrated Communications Controller
(PowerQUICC). The CPU on the MPC852T is the MPC8xx core,
a 32-bit microprocessor that implements the PowerPC
architecture, incorporating memory management units (MMUs)
and instruction and data caches. The MPC852T is the subset of
this family of devices.
