Product Summary
The spea122800 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 spea122800 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 spea122800 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).
