Z8018006VEC

Overview

The Z8018006VEC is an 8-bit microprocessor unit based on the Z80 architecture, operating at a maximum clock frequency of 6 MHz. It features a single core with an 8-bit data bus width and includes 64 kB of on-chip SRAM. The device supports a 5 V operating voltage and utilizes a 68-pin PLCC package for surface mount installation. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating extended instructions.
• Integrates two DMA channels, two UARTs, and two programmable reload timers directly on-chip.
• Includes an expanded Memory Management Unit (MMU) capable of addressing up to 1 MB.
• Features an internal oscillator/generator and three wait-state generators.

Applications

• Embedded systems requiring reduced component count through integrated peripherals
• Industrial control applications utilizing the extended temperature range
• Legacy Z80 system upgrades maintaining code compatibility

Procurement Notes

Verify the specific suffix 'VEC' against official Zilog documentation to confirm the exact package type and environmental compliance status. Confirm current availability as this series may be subject to discontinuation notices. Ensure design-in requirements match the 68-pin PLCC footprint and 5V logic levels specified in the datasheet.

Selection Notes

Select this component when a Z80-compatible processor with integrated memory and I/O peripherals is required. The 6 MHz speed and 64 kB SRAM suit moderate performance needs. Consider the 68-pin PLCC package for surface-mount designs requiring robust thermal performance across wide industrial temperature ranges.

Part Context

This part belongs to the Z80180 family of microprocessors, which are enhanced versions of the classic Z80 CPU. The family integrates system functions like DMA, UART, and timers to reduce external component counts. The Z8018006VEC specifically denotes the 6 MHz variant in a PLCC package with extended temperature capabilities.

Replacement Considerations

Consult official Zilog substitution guides for verified equivalents. Generic Z80 processors lack the integrated peripherals found in this MPU. Verify pinout compatibility if replacing with other Z80180 variants or similar legacy MPUs.
