Z8018008VEG00TR

Overview

The Z8018008VEG00TR is an enhanced microprocessor based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 8 MHz with an 8-bit data bus width and requires a 5 V supply voltage. The device integrates SRAM memory and includes two timer/counters along with SCI and UART interfaces. It is housed in a QFP-44 package and supports surface-mount installation. The component functions within a temperature range of 0°C to +70°C and features dynamic refresh control for external DRAM management.

Feature Summary

• Provides full backward compatibility with existing Z80 devices while reducing system costs
• Integrates SRAM memory and dual timer/counters for embedded control applications
• Includes built-in SCI and UART serial communication interfaces
• Supports dynamic refresh control for external DRAM systems

Applications

• Industrial control systems requiring Z80 compatibility
• Embedded applications utilizing serial communication via SCI or UART
• Systems integrating external DRAM with dynamic refresh requirements
• Cost-sensitive microprocessor designs using 8-bit architecture

Procurement Notes

Verify the exact suffix configuration against official Zilog documentation to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compliance with RoHS directives if required for your specific application environment. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when backward compatibility with legacy Z80 software is mandatory. Choose this part for designs requiring integrated SRAM and serial interfaces without external logic. Consider the 8 MHz speed limit and 5 V operation when defining system performance and power constraints. Evaluate the QFP-44 package size against available PCB real estate.

Part Context

This part belongs to the Z80180 series of enhanced microprocessors. The series combines the Z80 instruction set with additional peripherals like timers and serial ports. It serves as a drop-in replacement for standard Z80 CPUs in many applications while offering expanded functionality through integrated memory controllers and I/O capabilities.

Replacement Considerations

Direct substitutes include other variants within the Z80180 family such as Z8018008VSG or Z8018008FSG, provided the package type matches. Verify that alternative parts maintain the same 8 MHz speed grade and 5 V operating voltage. Check for differences in integrated memory size or interface configurations before substitution.
