Motorola PowerPC 603

PowerPC 603 is a low-power 32-bit microprocessor with RISC instruction set. The first implementation of the PowerPC 603 was based on 0.5 micron technology and featured 8 KB code and 8 KB data caches. Overall performance of this CPU was lower than similarly clocked Power PC 601. Processor performance was enhanced in the next revision of the chip - 603e. The 603e was manufactured on 0.35 micron CMOS process, had twice as large instruction and data caches, and included other minor performance improvements. The next revision of the family, 603ev, was a faster clocked revision of 603e. The forth, and the last, revision of the PowerPC 603 was 603et. This processor was manufactured on 0.29 micron technology, and was clocked at speeds from 200 to 300 MHz.
