PC755CMGU400LE

The NXP Semiconductors PC755CMGU400LE is a 32-bit PowerPC RISC microprocessor clocked at 400 MHz, supplied in a flip-chip ball grid array (FCBGA) package. It belongs to the MPC755 family derived from the PowerPC 750 core, featuring a superscalar pipeline that issues up to three instructions per cycle, separate 32 kB L1 instruction and data caches, an integrated double-precision floating-point unit, and a memory management unit. The processor uses a 60x system bus interface that simplifies connection to companion chipsets such as the MPC107, supporting symmetric multiprocessing and efficient memory access in deeply embedded systems.

Typical deployments span high-reliability and long-lifetime applications: avionics flight-control computers, radar and sonar signal processing, missile guidance, and industrial safety controllers. The FCBGA package, combined with extended-temperature screening variants noted by the suffix code, allows operation in harsh thermal and vibration environments without sacrificing processing determinism. For procurement, this part number’s specialized suffix indicates a specific screening level, temperature range, or lead-free finish; exact specifications should be confirmed against NXP ordering documentation. As a legacy PowerPC device, ongoing supply may be subject to NXP’s product longevity commitments or end-of-life management, making authorized distribution, counterfeit mitigation, and lifecycle planning essential for defense and aerospace programs with multi-decade sustainment requirements.
