Z84C0020FEG

Overview

The Z84C0020FEG is an 8-bit microprocessor based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 20 MHz and utilizes CMOS technology. The device is housed in a 44-lead Low Profile Quad Flat Package (LQFP) with dimensions of 10x10 mm. It functions within a supply voltage range of 5V and supports an industrial operating temperature range from -40°C to +100°C. This component is classified as a microprocessor (MPU) featuring a single core.

Feature Summary

• Implements the standard Z80 instruction set architecture for backward compatibility
• Utilizes CMOS technology for low power consumption
• Supports surface mount installation via LQFP package

Applications

• Industrial control systems requiring robust processing
• Embedded applications within extended temperature environments
• Legacy system maintenance and replacement

Procurement Notes

Verify the specific suffix 'FEG' against official Zilog documentation to confirm package type and temperature grade. Confirm availability status as this series may be subject to discontinuation or limited production runs. Ensure compliance with RoHS directives if required for the target application environment.

Selection Notes

Select this component when a pin-compatible Z80 processor is needed with a 20 MHz speed rating and industrial temperature tolerance. The LQFP-44 package is suitable for automated surface mount assembly processes. Consider alternative packages such as PLCC if lead-free soldering constraints differ from the specified requirements.

Part Context

This part belongs to the Z84C00 series of 8-bit microprocessors. It serves as a modern CMOS implementation of the classic Z80 CPU, designed to replace older NMOS variants while maintaining software and hardware compatibility. The series is widely used in embedded computing and legacy hardware preservation projects.

Replacement Considerations

Direct substitutes include other Z84C00 variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same 20 MHz performance and LQFP-44 form factor to ensure mechanical fit.
