P2020NXE2KHC

微处理器 - MPU P2020E ET 1000/800 R2.1

This P2020NXE2KHC document contains detailed information about power

considerations, DC/AC electrical characteristics, and AC

timing specifications for .13μm (HiP7) members of the

PowerQUICC II family of integrated communications

processors—the MPC8280, the MPC8275, and the

MPC8270 (collectively called the MPC8280 throughout this

document). 

Features P2020NXE2KHC

The major features of the SoC are as follows:

• Dual-issue integer (G2_LE) core

— A core version of the EC603e microprocessor

— System core microprocessor supporting frequencies of 166–450 MHz

— Separate 16 KB data and instruction caches:

– Four-way set associative

– Physically addressed

– LRU replacement algorithm

— Power Architecture®-compliant memory management unit (MMU)

Operating Conditions P2020NXE2KHC

This table shows the maximum electrical ratings.

This SoC contains circuitry protecting against damage due to high static voltage or electrical fields;

however, it is advised that normal precautions be taken to avoid application of any voltages higher than

maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused

inputs are tied to an appropriate logic voltage level (either GND or VCC).
