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.
