Embedded MPU with dual ARM926 core, flexible memory support, powerful connectivity features and programmable LCD interface

The SPEAr600 is a member of the SPEAr family of embedded MPUs for networked devices, it is based on dual ARM926EJ-S processors (up to 333 MHz), widely used in applications where high computation performance is required.

Both processors have an MMU supporting virtual memory management and making the system compliant with the Linux operating system. They also offer 16 KBytes of data cache, 16 KBytes of instruction cache, JTAG and ETM (embedded trace macro-cell) for debug operations.

To expand its range of target applications, SPEAr600 can be extended by adding additional peripherals through the external local bus (EXPI interface).
