SPEAr320中文资料Embedded MPU optimized for factory automation and consumer applications数据手册ST规格书

描述 Description

The SPEAr320 is a member of the SPEAr family of embedded MPUs, optimized for industrial automation and consumer applications. It is based on the powerful ARM926EJ-S processor (up to 333 MHz), widely used in applications where high computation performance is required.
In addition, SPEAr320 has an MMU that allows virtual memory management - making the system compliant with Linux operating system. It also offers 16 KB of data cache, 16 KB of instruction cache, JTAG and ETM (Embedded Trace Macrocell) for debug operations.
A full set of peripherals allows the system to be used in many applications, some typical applications being factory automation, printer and consumer applications.

简介

SPEAr320属于集成电路（IC）的微处理器。由制造生产的SPEAr320微处理器微处理器产品是用于信息和数据处理的集成电路。与主要按照制造商所选术语而视为微控制器的类似产品相比，这些器件有所不同。但是按照传统，微处理器不会在设备内集成工作存储器，不太可能集成混合信号外设，并且可能在更为复杂的软件范式下使用，这些范式涉及使用操作系统来管理多任务同时执行。
