描述：
,Designed for engine management, the Qorivva MPC5553 32-bit embedded controller is the first device from Freescale's Qorivva MPC55xx family to offer an on-chip fast Ethernet controller (FEC). Containing the Power Architecture? core, the Qorivva MPC5553 is ideal for any application that requires complex, real-time control and can conveniently be networked with the rest of the world. It offers system performance of up to five times that of its MPC500 predecessors, while bringing you the reliability and familiarity of the proven Power Architecture technology.,
