MPC5554MZP80

The Freescale MPC5554 MCU enables complex, real-time control for engine management systems. It offers system performance of up to five times that of its MPC500 predecessors along with the reliability and familiarity of proven Power Architecture technology. Reduces costs by integrating more functionality on-chip Development support speeds time-to-market Supports multiple protocols and customer requirements through intelligent subsystems Offers a migration path from the MPC500 MCUs, facilitating reuse of legacy software architectures
