Z8018008VEC00TR

Overview

The Z8018008VEC00TR is an 8-bit microprocessor unit based on the Z80 architecture, operating at a maximum clock frequency of 8 MHz. It integrates two DMA channels, two UARTs, and two programmable reload timers within a single chip. The device supports extended memory addressing up to 1 MB via an on-chip MMU and includes three wait-state generators. It operates on a 5 V supply with a commercial temperature range of 0°C to +70°C. The component is housed in a 68-pin PLCC package.

Feature Summary

• Full backward compatibility with existing Zilog Z80 devices while providing an extended instruction set.
• Integrated system functions including dual DMA controllers, asynchronous serial communication interfaces, and timer channels.
• Support for expanded memory addressing up to 1 MB through an integrated Memory Management Unit.
• Low power-down modes and on-chip interrupt controllers for efficient system management.

Applications

• Industrial control systems requiring robust I/O integration
• Embedded applications needing direct memory access capabilities
• Systems utilizing asynchronous serial communication protocols

Procurement Notes

Verify the specific suffix 'VEC00TR' against official Zilog documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the 8 MHz speed grade matches the design requirements. Check for end-of-life status as older Z80180 variants may be discontinued. Ensure RoHS compliance aligns with current environmental regulations.

Selection Notes

Select this variant when an 8 MHz processing speed is sufficient for the application. Choose the PLCC package if surface mount technology is required but QFP availability is limited. Consider the integrated peripherals to reduce external component count compared to standard Z80 implementations. Verify voltage levels match the 5 V system requirement.

Part Context

This part belongs to the Z80180 family of microprocessors, which are enhanced versions of the classic Z80 CPU. The family offers code compatibility while adding significant on-chip resources like DMA and UARTs. The Z80180 series was designed to reduce system costs by integrating peripheral functions directly onto the processor die.

Replacement Considerations

Consult official Zilog cross-reference guides for verified substitutes. Generic Z80 clones may lack the specific integrated peripherals found in the Z80180 series. Verify pinout compatibility if replacing with other packages in the same family.
