IBM demonstrated a new low power PowerPC-based system-on-chip processor running MontaVista Linux at LinuxWorld this week. The new PowerPC based system-on-chip processor, which seems poised to compete with Intel's XScale processors for mobile device design wins, is described in its preliminary data sheet as a “highly integrated device offering high-performance at ultra-low power”.

The chip contains a PowerPC 405D4 core processor (with MMU) which dynamically scales from 152 to 380 MHz, and also includes an SDRAM/RAM/ROM/Flash controller, DMA and interrupt controllers, extensive power management, color LCD controller for 1/4 VGA up to XGA (2K x 2K pixels), touch panel interface, 2 16550-type serial ports, IIC (master and slave), CODEC interface, and up to 32 general purpose I/O lines.

The new PowerPC 405LP will begin sampling during the first quarter of 2003, according to an IBM representative.
