• Integrates internal L2 tag combined with a dedicated L2 cache interface.
• Supports low-power management modes including doze, nap, and sleep.
• Includes integrated thermal management assist unit for junction temperature regulation.

Applications

• Low-cost embedded systems
• Low-power computing applications
• Automotive electronics requiring AEC-Q100 compliance

Procurement Notes

Verify component authenticity through official NXP channels due to discontinued status. Confirm package type matches system requirements as both CBGA and PBGA variants exist within the family. Ensure power supply specifications align with recommended operating conditions before integration.

Selection Notes

Select this part for designs requiring PowerPC compatibility with specific thermal constraints. Consider the CBGA package for interconnect reliability needs. Verify that the required L2 cache configuration is supported by the external memory controller design.

Part Context

This component belongs to the MPC755 RISC Microprocessor family implementing the PowerPC architecture. It shares functional similarities with the MPC745 but adds an internal L2 cache interface. The device utilizes 0.22 µm CMOS technology and is designed for systems prioritizing power efficiency alongside processing performance.

Replacement Considerations

Consult NXP sales offices for current upgrades as the product is no longer in production. No direct public substitute part numbers are confirmed in available documentation.
