Microprocessors Procurement Notes

Verify the manufacturer designation carefully, as this component is historically associated with Intel but may be listed under Altera in certain distribution channels due to corporate acquisitions. Confirm the specific package type and pin count match your design requirements. Ensure compliance with relevant environmental standards such as RoHS if applicable to your deployment region. Cross-reference the S-spec number for precise stepping verification.

Microprocessors Selection Notes

Select this processor for applications requiring a balance of x86 compatibility and mobile power efficiency. The 500 MHz speed and integrated cache suit general-purpose embedded tasks. Consider thermal dissipation capabilities inherent to the PBGA package when designing the system board. Verify software driver support for the target operating environment prior to integration.

Microprocessors Part Context

This component belongs to the Mobile Pentium III series, leveraging the Coppermine microarchitecture. It represents a generation of processors focused on reducing power consumption while maintaining performance for portable devices. The part integrates floating-point operations and benefits from the 0.18-micron manufacturing process typical of its era.

Microprocessors Replacement Considerations

Compatible substitutes within the same family include the KC80526GL700256, which offers a higher clock speed of 700 MHz. Both parts share the same 495-ball PBGA package and architectural foundation, ensuring mechanical and functional interchangeability in compatible designs.
