Z84C0008VEC

Overview

The Z84C0008VEC is a CMOS microprocessor based on the Z80 architecture, manufactured by Zilog. It operates with an 8-bit data bus width and supports a maximum clock frequency of 8 MHz. The device functions at a supply voltage of 5 V and utilizes a PLCC-44 surface-mount package. It features an integrated UART interface for serial communication. The component is rated for an extended industrial temperature range from -40°C to +100°C. As part of the Z84C0008 series, it provides a comprehensive instruction set compatible with legacy systems while offering improved power efficiency compared to NMOS predecessors.

Feature Summary

• Implements the Z80 processor core architecture within a single-core design.
• Integrates a Universal Asynchronous Receiver/Transmitter (UART) for direct serial connectivity.
• Supports surface-mount installation via a PLCC-44 package configuration.
• Operates reliably across extended industrial temperature environments.

Applications

• Industrial control systems requiring robust serial communication
• Embedded applications utilizing legacy Z80 software architectures
• Data acquisition modules needing integrated UART functionality

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm that the PLCC-44 package matches your PCB footprint requirements. Ensure your design supports the specified 5V logic levels and operating temperature range. Check for any specific environmental compliance documentation required for your region before finalizing procurement plans.

Selection Notes

Select this component when a CMOS-based Z80 replacement is needed with integrated serial capabilities. The PLCC-44 package suits designs prioritizing surface-mount technology. Consider the 8 MHz speed limit for timing-critical applications. Verify compatibility with existing 5V power supplies and I/O interfaces. Evaluate thermal management needs given the extended temperature rating.

Part Context

This microprocessor belongs to the Z84C0008 series, which represents the CMOS evolution of the classic Z80 CPU line. It serves as a drop-in replacement for older NMOS variants like the Z8400 in many designs. The series maintains binary compatibility with the original Z80 instruction set while reducing power consumption. It is designed for applications transitioning from through-hole to surface-mount manufacturing processes.

Replacement Considerations

The Z84C0008AEG offers identical functional specifications but utilizes a QFP-44 package instead of PLCC-44. Designers must verify pinout compatibility between these packages if substituting. Other series members like the Z84C0006VEG operate at lower clock speeds. Ensure mechanical fitment is validated before replacing the PLCC-44 variant with a QFP version.
