ST 公司的SPEAr310是采用ARM926EJ-S处理器(高达333MHz)的嵌入MPU,具有高性能的8路DMA,动态省功耗特性,可配置的外设功能,具有扩展的连接特性,主要用在路由器,交换和网关,遥控和计量集中器.本文介绍了SPEAr310主要特性,方框图,采用SPEAr310的系统架构图以及评估板EVALSPEAr310主要特性,方框图,电路图,材料清单和PCB布局图.

The SPEAr310 is a member of the SPEAr family of embedded MPUs, optimized for telecom 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, SPEAr310 has an MMU that allows virtual memory management -- making the system compliant with advanced operating systems, like Linux. It also offers 16 KB of data cache, 16 KB of instruction cache, JTAG and ETM (embedded trace macro-cell) for debug operations.

A full set of peripherals allows the system to be used in many applications, some typical applications being routers, switches and gateways as well as remote apparatus control and metering concentrators.

SPEAr310主要特性:

■ ARM926EJ-S 333 MHz core

■ High-performance 8-channel DMA

■ Dynamic power-saving features

■ Configurable peripheral functions multiplexed on 102 shared I/Os

■ Memory:
