Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part does not meet current environmental standards. Validate package integrity upon receipt, ensuring no damage to the 100-QFP pins. Check manufacturing date codes against project timelines given the discontinuation notice from July 2009. Ensure supply chain stability for long-term production support.

Selection Notes

Select this component when maintaining compatibility with existing Z8S180 software codebases. Consider the 33MHz operating frequency relative to system timing requirements. Evaluate the 100-QFP footprint against available PCB real estate. Assess thermal performance within the specified 0°C to 70°C operational range. Verify that 5.0V I/O levels match the target system voltage domains.

Part Context

This part belongs to the Z80195 series of microprocessors produced by Zilog. It represents an evolution of the classic Z80 architecture with enhanced peripheral integration. The Z8S180 core provides backward compatibility while adding modern interface capabilities. This specific variant denotes the 33MHz speed grade within the QFP package family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The product status is listed as End of Life with a discontinuation notice dated July 24, 2009. Designers should evaluate alternative microcontrollers with compatible pinouts and instruction sets if sourcing new units is required.
