Z84C0008PEC

Overview

The Z84C0008PEC is a CMOS Central Processing Unit (CPU) belonging to the Z80 family, manufactured by Zilog. It features an 8-bit data bus width and operates with a maximum clock frequency of 8 MHz. The device is designed for industrial temperature ranges, supporting operation from -40 °C to +100 °C. It utilizes a 44-lead Plastic Quad Flat Package (QFP-44) for surface mount installation. The component requires a nominal supply voltage of 5 V and includes UART interface capabilities within its architecture.

Feature Summary

• Implements the Z80 instruction set architecture in CMOS technology
• Supports industrial-grade wide temperature operational range
• Integrates UART interface functionality

Applications

• Industrial control systems requiring robust environmental tolerance
• Embedded applications utilizing Z80 architecture compatibility
• Legacy system maintenance and replacement projects

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity upon receipt as the QFP-44 form factor is sensitive to handling. Ensure compliance with applicable export regulations and environmental directives relevant to the procurement region before finalizing acquisition.

Selection Notes

Select this component when a surface-mount solution compatible with the Z80 instruction set is required for industrial environments. The 8 MHz speed and 5 V operation align with standard legacy designs. Consider the QFP-44 footprint constraints during PCB layout planning to ensure adequate clearance and thermal management for the specified operating temperature range.

Part Context

This CPU is part of the broader Z84C00 series, which provides various speed grades and package options for the Z80 core. It serves as a direct CMOS successor to earlier NMOS variants, offering improved power efficiency while maintaining pin and instruction set compatibility. The specific PEC suffix denotes the plastic quad flat package variant optimized for automated surface mounting processes.

Replacement Considerations

Direct substitutes include other Z84C0008 variants such as Z84C0008VEG or Z84C0008AEG, depending on package preference. Verify that any replacement maintains the 8 MHz clock requirement and industrial temperature rating to ensure functional equivalence in existing designs.
