Z84C3008FEG

Overview

The Z84C3008FEG is an 8 MHz CMOS Counter/Timer Circuit (CTC) manufactured by Zilog, Inc. It operates on a single 5 V supply and supports an external data bus width of 8 bits. The device is housed in a 44-pin Plastic Quad Flat Package (PQFP) with dimensions specified as QFP44,.47SQ,32. It functions within a temperature range of -40 °C to +100 °C. This component serves as a specialized timer and support product compatible with the Z80 architecture.

Feature Summary

• Integrated 8 MHz CMOS Counter/Timer Circuit (CTC)
• Single 5 V power supply operation
• 44-pin PQFP surface-mount package
• Extended industrial temperature range (-40 °C to +100 °C)

Applications

• Z80-based microprocessor system timing
• Industrial control timer circuits
• Embedded system clock generation

Procurement Notes

Verify component authenticity through authorized Zilog distributors or certified secondary market suppliers. Confirm the specific suffix 'FEG' corresponds to the required plastic quad flat package variant and extended temperature rating. Request manufacturer documentation to validate RoHS compliance status and ensure the part matches the original design specifications for critical applications.

Selection Notes

Select this component when an 8-bit CTC is required for Z80-compatible designs operating at 8 MHz. Ensure the PCB layout accommodates the 44-pin PQFP footprint. Verify that the thermal management strategy supports the -40 °C to +100 °C operating range. Compare against other Z84C30xx variants if different clock speeds or package types are needed.

Part Context

This part belongs to the Z84C30 series of CMOS Counter/Timer Circuits produced by Zilog. It complements the Z80 microprocessor family by providing hardware timer functionality. Other members in this series include variants with different clock frequencies and package options, such as the Z84C3006 and Z84C3010 models.

Replacement Considerations

Direct substitutes within the same family include the Z84C3008AEG and Z84C3008FEC. Verify pin compatibility and electrical characteristics before substitution. Cross-reference datasheets to confirm identical package dimensions and thermal performance for seamless integration.
