MPC8241LZQ266D

Overview

The MPC8241LZQ266D is a 32-bit integrated host processor featuring a PowerPC 603e core operating at 266 MHz. It integrates a PCI bridge supporting up to 66 MHz, a memory controller for up to 2 GB of SDRAM, and dual DMA controllers. The device utilizes a 357-pin plastic ball grid array (PBGA) package with dimensions of 25 x 25 mm. Core voltage is 1.8 V, while I/O supplies support 3.3 V or 5.0 V tolerance.

Feature Summary

• Integrates a high-performance superscalar PowerPC 603e core with floating-point capabilities and lockable L1 caches.
• Includes an on-chip PCI 2.2-compatible bridge supporting 5.0-V tolerant inputs and agent mode operations.
• Features a high-bandwidth memory controller supporting SDRAM with ECC options and extensive ROM/Flash interfaces.
• Provides integrated peripherals including dual UARTs, I2C controllers, message units, and programmable interrupt controllers.

Applications

• Network infrastructure control processing
• Telecommunications equipment
• Router and switch management
• Network storage applications

Procurement Notes

Verify the specific suffix 'LZQ' against official NXP documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board designs regarding the 357-pin PBGA footprint and thermal requirements. Confirm that the 266 MHz frequency bin matches system timing constraints. Check for end-of-life status or alternative sourcing channels as this component may be discontinued.

Selection Notes

Select this processor for embedded systems requiring high integration of PCI and memory interfaces within a single chip. It is suitable for applications where reducing discrete component count and board space is critical. Consider the dynamic power management features if energy efficiency during idle states is required. Evaluate the 266 MHz performance against specific computational loads for network control tasks.

Part Context

This component belongs to the PowerQUICC II family of integrated communications processors. It is based on the MPC8245 design but offers a simplified peripheral set optimized for cost-sensitive applications. The MPC8241 serves as a bridge between standard PCI peripherals and embedded control logic, leveraging the mature PowerPC architecture for software compatibility.

Replacement Considerations

Consult official NXP documentation for direct pin-to-pin replacements or functional equivalents within the MPC82xx family. Verify that any substitute maintains the same 357-pin PBGA package and electrical characteristics. Cross-reference feature sets to ensure adequate peripheral support for the target application.
