DESCRIPTION
The PC7447A features 512 KB of on-chip L2 cache. The PC7447A microprocessor has no backside L3 cache, allowing for a smaller package designed as a pin-for-pin replacement for the PC7447 microprocessor. This device benefits from a silicon-on-insulator (SOI) CMOS process technology, engineered to help deliver tremendous power savings without sacrificing speed.
