Product Summary

The SPEAR300-2 is an embedded MPU 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, the SPEAR300-2 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. The applications of the SPEAR300-2 include General purpose NAND Flash or NOR Flash based devices, Digital photo frames, WiFi or IP phones (low end or high end), ATA PABX systems (with or without I2S), 8-bit or 14-bit camera (with or without LCD).
