PC745 - ATMEL

PC745 32-bit RISC Microprocessor

The PC755 and PC745 PowerPC® microprocessors are high-performance, lowpower, 32-bit implementations of the PowerPC Reduced Instruction Set Computer (RISC) architecture, especially enhanced for embedded applications. The PC755 and PC745 microprocessors differ only in that the PC755 features an enhanced, dedicated L2 cache interface with on-chip L2 tags. The P.
