Device overview

The SPEAr320S 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, SPEAr320S 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 MacrocellTM) 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.

Figure 1 is the internal connectivity block diagram of SPEAr320S.

Table 2 lists the device IP groups and their constituent IPs.
