PC755CMGH400LE

The NXP PC755CMGH400LE is a 32-bit PowerPC RISC microprocessor operating at 400 MHz, designed to deliver reliable embedded processing for high-reliability applications. Built on the MPC755 (PowerPC 755) architecture, it integrates a superscalar pipeline, dedicated 32 KB on-chip L1 instruction and data caches, and a high-bandwidth L2 cache controller supporting external SRAM. A double-precision floating-point unit and memory management unit are included, while the FCBGA package offers a compact footprint with efficient thermal dissipation suited for densely populated boards.

Typical deployment scenarios span industrial control, avionics, defense electronics, and ruggedized networking infrastructure where deterministic execution under thermal stress is essential. The LE suffix indicates an extended temperature range, commonly -40°C to +105°C, allowing the device to operate in harsh environments without forced airflow. Procurement and design engineers should treat the MPC755 series as a mature, legacy platform; the LE screening provides an industrial-grade quality baseline, though long-term availability planning and proactive obsolescence mitigation remain critical for sustaining production programs.
