Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific part number matches the required speed grade and package type. Ensure compliance with RoHS directives if applicable to your region. Check for any available errata documents relevant to this hardware revision before finalizing procurement decisions.

Selection Notes

Select this component when designing systems based on the PowerPC architecture requiring moderate processing speeds. Consider the CBGA package constraints during PCB layout planning. Evaluate thermal dissipation requirements against the specified junction-to-ambient resistance values. Ensure the system design accommodates the specific voltage levels for core and I/O supplies.

Part Context

This microprocessor belongs to the MPC755 family, which shares architectural similarities with the MPC745 series. The primary distinction lies in the inclusion of an internal L2 cache controller in the MPC755 variant. These devices are designed for low-power applications and utilize 0.22 µm CMOS technology. The family targets cost-sensitive markets while maintaining high computational throughput.
