MPC8245LZU350D

Overview

The MPC8245LZU350D is a PowerPC-based integrated processor featuring the MPC603e core operating at 350 MHz. It integrates a PCI bridge, memory controller, and peripheral logic in a 352-pin TBGA package. The device supports up to 2 GB of SDRAM with ECC or parity options. Core supply voltage ranges from 1.9 V to 2.2 V DC for this frequency class. I/O supplies operate at 3.0 V to 3.6 V DC. The component operates within a junction temperature range of 0 °C to 105 °C.

Feature Summary

• Integrates a high-performance superscalar MPC603e processor core with floating-point support and lockable L1 caches.
• Includes a 32-bit PCI interface compatible with PCI 2.2 standards, supporting both host and agent modes.
• Features a dual-channel DMA controller with scatter-gather capabilities and direct memory access between local and PCI spaces.
• Provides an integrated message unit with I2O support and programmable interrupt controllers.

Applications

• Network infrastructure systems requiring high-speed data processing
• Telecommunications equipment utilizing standard interfaces
• Embedded routers and switches
• Network storage applications

Procurement Notes

Verify the specific suffix 'LZU' against official NXP documentation to confirm pinout and thermal specifications. Confirm that the 350 MHz speed grade matches system requirements. Check for end-of-life status as Freescale/NXP has discontinued many MPC82xx variants. Ensure compatibility with existing board designs regarding power sequencing and voltage levels.

Selection Notes

Select this component when a high-integration solution combining a PowerPC core with PCI connectivity is required. Consider the 350 MHz performance tier relative to lower-frequency variants like the 266 MHz or 333 MHz versions. Evaluate power consumption characteristics in doze and sleep modes for energy-sensitive designs. Verify memory controller support for the intended SDRAM density and timing parameters.

Part Context

This part belongs to the MPC82xx family of integrated processors designed by Freescale Semiconductor (now NXP). These devices target embedded markets needing robust peripheral integration alongside a powerful RISC core. The MPC8245 specifically bridges the gap between general-purpose processing and specialized I/O handling through its unified architecture.

Replacement Considerations

Consult official replacement lists for discontinued Freescale products. No direct public substitute part numbers are confirmed in the provided source material. Cross-reference with other MPC82xx variants if frequency or pinout differences are acceptable.
