Z8018006PSG

Overview

The Z8018006PSG 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 supports a 5 V operating voltage. The device includes 64 kB of on-chip SRAM and integrates two UARTs, two 16-bit counter/timers, and two DMA channels. It utilizes a 64-pin DIP package for through-hole mounting and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating extended instructions.
• Integrates key system functions on-chip including DMA controllers, UARTs, timers, wait-state generators, and an interrupt controller.
• Supports expanded memory addressing up to 1 MB via an integrated Memory Management Unit (MMU).
• Includes low power-down modes and an on-chip oscillator/generator for reduced system costs.

Applications

• Embedded control systems requiring Z80 code compatibility.
• Industrial automation applications utilizing integrated serial communication interfaces.
• Data acquisition systems leveraging on-chip timer and DMA resources.
• Cost-sensitive designs benefiting from reduced external component count.

Procurement Notes

Verify the specific suffix 'PSG' against official Zilog documentation to confirm lead-free environmental compliance and package type accuracy. Confirm availability status as distribution channels may list this component as obsolete or limited supply. Ensure the 64-pin DIP form factor matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a Z80-compatible processor with integrated peripherals is required. Consider the 6 MHz speed limit and 64 kB SRAM capacity against application demands. Evaluate the 64-pin DIP package constraints versus surface-mount alternatives like PLCC or QFP if space is limited. Verify that the 5 V logic level and commercial temperature range meet system specifications.

Part Context

The Z80180 series belongs to Zilog's enhanced microprocessor family, designed to bridge legacy Z80 software with modern integrated peripheral capabilities. This specific model represents the 6 MHz variant in a dual-in-line package, offering a balance of processing performance and peripheral integration for standard embedded applications without requiring complex external memory or I/O expansion.

Replacement Considerations

Consult official Zilog substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully when considering alternative packages such as the 68-pin PLCC or 80-pin QFP variants within the same family.
