PC8245MTPU300D

The PC8245MTPU300D is a high-reliability integrated host processor from NXP Semiconductors, combining a PowerPC 603e core operating at 300 MHz with a PCI 2.2-compliant bridge, SDRAM memory controller, and a suite of embedded peripherals in a single-chip TBGA package. This processor is part of the MPC8245 family, architected for embedded applications requiring integrated system functions and deterministic performance. The device’s high-reliability screening (indicated by the HiRel grade variant) qualifies it for extended temperature ranges and rigorous environments, with die processing and testing tailored to industrial, aerospace, and defense standards. Key architectural features include a 32-bit RISC core, on-chip DMA engine, dual UARTs, I²C interface, and a programmable interrupt controller, all connected through a high-bandwidth internal bus that minimizes chip-count for compact designs.

Typical deployments include single-board computers for avionics mission systems, ruggedized industrial controllers, radar and sonar signal processing units, and secure military communication nodes where long lifecycle support is mandatory. The TBGA package enables reliable surface-mount assembly and thermal management in conduction-cooled enclosures. From a procurement standpoint, this HiRel variant should not be confused with standard commercial versions; supply is often spot-buy or build-to-order, and sourcing partners must confirm traceability to NXP’s authorized distribution chain. Design engineers and buyers should plan for potentially extended lead times and consider device obsolescence management, as powerful but older processor families like the MPC8245 are subject to limited availability. Verification of authentic packaging, date codes, and human-body-model ESD handling is essential to maintain system-level reliability.
