SPEAr310:Embedded MPU optimized for automation and consumer applications

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.
