Z84C0008PEG

Overview

The Z84C0008PEG is a CMOS microprocessor belonging to the Z80 family, manufactured by Zilog. It operates as an 8-bit Central Processing Unit with a maximum clock frequency of 8 MHz. The device utilizes a 44-pin Plastic Leaded Chip Carrier (PLCC) package designed for surface-mount installation. It functions within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +100°C. The component integrates the full Z80 instruction set architecture.

Feature Summary

• Implements the complete Z80 instruction set architecture in CMOS technology
• Provides high-speed processing capability at up to 8 MHz clock frequency
• Features industrial-grade thermal stability suitable for wide temperature environments

Applications

• Industrial control systems requiring robust 8-bit processing
• Embedded applications utilizing standard Z80 software ecosystems
• Automotive electronics operating under extended temperature conditions

Procurement Notes

Verify current availability status as discontinuation notices have been issued for this product line. Confirm package integrity upon receipt, as PLCC components require careful handling during soldering. Ensure compatibility with existing board layouts before procurement, given the end-of-life status. Consult official manufacturer documentation for final replacement strategies.

Selection Notes

Select this component only when legacy Z80 software compatibility is mandatory. The PLCC-44 package requires specific surface-mount assembly processes distinct from through-hole alternatives. Evaluate thermal management requirements against the specified 100°C upper limit. Consider pin-compatible successors if new designs are initiated, as supply continuity is not guaranteed.

Part Context

This processor is part of the Z84C00 series, representing the CMOS evolution of the classic Z80 architecture. Zilog has announced the cessation of production for the Z80 family due to market shifts toward RISC architectures. This specific model serves as a bridge component for maintaining older hardware systems while transitioning to modern silicon solutions.

Replacement Considerations

Official substitutes include the Z84C0006PEG and Z84C0010PEG within the same series. Verify pinout compatibility before substitution. Open-source silicon projects offer FOSS alternatives for long-term sustainability.
