1 / 80 page  © Freescale Semiconductor, Inc., 2004. All rights reserved. Freescale Semiconductor Technical Data This document contains detailed information for the MPC852T 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 MPC852T contains a PowerPC TM processor core. 1 Overview The MPC852T PowerQUICC TM is a 0.18-micron derivative of 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. MPC852TEC Rev. 3.1, 01/2005 Contents 1. Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 2.
