STMicroelectronics Spear300

Beschreibung

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 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 HMI, Security and VoIP phones.
