SPEAr300：Embedded MPU optimized for VoIP, HMI and security applications

The SPEAr300 is a member of the SPEAr family of embedded MPUs for networked devices.

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, SPEAr300 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 macro-cell) for debug operations.

A full set of peripherals allows the system to be used in many applications, some typical applications being HMI, Security and VoIP phones.
