Z84C0008VEG

Overview

The Z84C0008VEG is a microprocessor based on the Z80 core 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 includes UART interface capabilities. It is housed in a 44-PLCC (J-Lead) surface-mount package. The component is rated for an operating temperature range from -40°C to +100°C. It complies with RoHS3 standards and carries an MSL rating of 3.

Feature Summary

• Integrates Z80 CMOS CPU core with built-in UART functionality
• Supports high-temperature industrial operation up to 100°C
• Designed for surface-mount assembly in compact PLCC packages

Applications

• Access control systems
• Industrial automation controllers
• Embedded terminal devices

Procurement Notes

Verify current availability status as this part has been officially discontinued by the manufacturer. Check for Product Change Notifications regarding packaging or sourcing updates. Confirm that replacement components meet identical pinout and electrical specifications for direct integration into existing designs without circuit modification.

Selection Notes

Select this component only if legacy Z80 software compatibility is required alongside integrated serial communication. Ensure design constraints accommodate the specific 44-PLCC footprint and 5V logic levels. Evaluate thermal management requirements given the wide operating temperature range and surface-mount configuration limitations.

Part Context

This unit belongs to the Z84C00 series of 8-bit microprocessors derived from the classic Z80 instruction set. It represents a CMOS implementation optimized for lower power consumption compared to earlier NMOS versions while maintaining functional parity. The VEG suffix denotes specific packaging and environmental compliance characteristics within the product line.

Replacement Considerations

Z84C0008AEG: Offers identical processing performance but utilizes a QFP-44 package instead of PLCC. Verify mechanical fit and soldering profile differences before substitution.
