SPEAR320-2

嵌入式MPU与ARM926内核，用于工厂自动化和消费应用而优化 Embedded MPU with ARM926 core, optimized for factory automation and consumer applications

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.
