Z8018008FSG

Overview

The Z8018008FSG is an 8-bit microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 8 MHz with a single core and an 8-bit data bus width. The device utilizes a QFP-80 package for surface mount installation and functions within a commercial temperature range of 0°C to +70°C. It requires a 5 V operating supply voltage and incorporates 64 kB of SRAM storage type memory. Key interface capabilities include SCI and UART communication protocols.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating extended instructions.
• Integrates two DMA channels, two UARTs, and two 16-bit counter/timers directly on-chip to reduce system costs.
• Features an expanded Memory Management Unit (MMU) allowing addressing up to 1 MB.
• Includes low power-down modes and three on-chip wait-state generators.

Applications

• Embedded systems requiring Z80 code compatibility with integrated peripheral resources
• Industrial control applications utilizing on-chip serial communication interfaces
• Memory management intensive designs accessing extended address spaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm lead-free environmental compliance specifications match project requirements. Ensure handling procedures account for moisture sensitivity levels specified in datasheets. Validate that the specific ordering suffix corresponds to the required package and temperature grade before finalizing acquisition.

Selection Notes

Select this component when legacy Z80 software compatibility is mandatory alongside integrated peripheral functionality. Consider the QFP-80 package constraints for PCB layout and thermal management. Evaluate the 8 MHz operational speed against processing requirements. Verify that the 5 V logic level aligns with system I/O voltages and that the commercial temperature range meets environmental conditions.

Part Context

This part belongs to the Z80180 family of microprocessors, which are enhanced versions of the classic Z80 CPU. The family integrates various system functions such as DMA controllers, timers, and serial ports onto a single chip. This specific model represents the 8 MHz variant housed in an 80-pin Quad Flat Package, designed for surface-mount technology applications.
