PC755BEGH300LE

The NXP Semiconductors PC755BEGH300LE is a 32‑bit PowerPC 755 RISC microprocessor from the MPC755 family, supplied in a flip‑chip ball grid array (FCBGA) package. Operating at a 300 MHz core frequency, the device incorporates superscalar execution, separate L1 instruction and data caches, an on‑chip L2 cache controller, a double‑precision floating‑point unit, and a memory management unit, delivering deterministic high‑throughput computation for deeply embedded systems. The FCBGA package offers a low‑profile, high‑density interconnect suited to thermally constrained boards where board area and signal integrity are critical. The suffix “LH300LE” designates a specific combination of speed grade, temperature range, and screening flow aimed at high‑reliability environments; such variants commonly support extended‑temperature operation and adhere to controlled manufacturing and traceability flows.

Typical applications include embedded avionics, radar and sonar processing, mission computers, ruggedized industrial automation, and high‑end networking infrastructure that demand long‑lifecycle, dependable processing. As a mature PowerPC product, the PC755BEGH300LE should be evaluated for supply‑chain stability; obsolescence risk and extended factory lead times can affect program sustainment, making proactive lifetime‑buy and form‑fit‑function replacement planning essential. Procurement and design engineers must verify the exact screening designation (industrial, extended, or application‑specific) against the NXP ordering guide, because the suffix controls valid supply voltage, temperature range, and reliability qualification levels. Sourcing through authorized distribution channels supports traceability and certification documentation required for defense, aerospace, and other high‑reliability deployments.
