Z84C0006AEG

Overview

The Z84C0006AEG is an 8-bit microprocessor based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 6 MHz and utilizes CMOS technology. The device is housed in a 44-lead Plastic Quad Flat Package (PQFP) with a pitch of 0.47 mm. It features an 8-bit external data bus and a 16-bit address bus. The component supports low-power modes and functions within a temperature range of -40°C to +100°C.

Feature Summary

• Implements the Z80 instruction set architecture for legacy compatibility
• Integrates low-power operational modes for energy efficiency
• Provides parallel I/O capabilities via dedicated control signals

Applications

• Industrial control systems requiring Z80 compatibility
• Embedded applications in harsh thermal environments
• Legacy system maintenance and replacement

Procurement Notes

Verify RoHS compliance status as historical records indicate variations between compliant and non-compliant manufacturing runs. Confirm package integrity upon receipt, as surface-mount packages are sensitive to moisture. Ensure design-in documentation matches the specific suffix requirements for your application voltage and temperature constraints.

Selection Notes

Select this component when a 6 MHz processing speed is sufficient for the target application logic. Compare against higher-speed variants like the Z84C0020 if performance upgrades are required. Verify that the 44-pin PQFP footprint aligns with existing PCB layouts. Consider power consumption differences compared to older NMOS Z80 implementations.

Part Context

This part belongs to the Z84C00 series of CMOS microprocessors, which serve as direct replacements for the original NMOS Z80 CPU. The series offers improved power efficiency and noise immunity while maintaining pin-to-pin compatibility with legacy designs. It is widely used in embedded controllers where established software ecosystems rely on the Z80 instruction set.

Replacement Considerations

Direct substitutes include other Z84C00 series variants with different clock speeds, such as the Z84C0008 or Z84C0020, provided the package remains identical. Cross-vendor Z80-compatible processors may require firmware adaptation.
