Z8018006VSC

Overview

The Z8018006VSC 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 utilizes SRAM storage type for its integrated memory. The device operates within a voltage range of 4.5 V to 5.5 V, typically centered at 5 V. It supports interfaces including ASCI and UART. The component is housed in a PLCC-68 package designed for surface mount installation.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating reduced system costs through on-chip integration.
• Includes two DMA channels for high-speed transfers between memory and I/O devices without CPU intervention.
• Integrates two asynchronous serial communication interface (ASCI) channels supporting full-duplex UART functionality.
• Features an expanded Memory Management Unit (MMU) allowing access to up to 1 MB of physical memory space.

Applications

• Industrial control systems requiring robust serial communication
• Embedded applications needing direct memory access capabilities
• Legacy Z80 system upgrades with extended memory addressing

Procurement Notes

Verify the specific suffix 'VSG' or 'VSC' against official datasheets to confirm lead-free compliance and temperature ratings. Confirm package integrity for PLCC-68 components. Check for end-of-life status as distribution may be limited. Ensure environmental compliance documentation matches project requirements before finalizing orders.

Selection Notes

Select this variant when a 6 MHz processing speed is sufficient for the application logic. Choose the PLCC-68 package for surface-mount board designs requiring a compact footprint. Consider the integrated MMU if the application requires mapping logical addresses beyond the standard 64 KB limit. Verify that the 5 V operating voltage aligns with the target system power supply rails.

Part Context

This component belongs to the Z80180 family of microprocessors, which are enhanced versions of the classic Z80 CPU. The family integrates peripheral functions such as timers, DMA controllers, and serial ports directly onto the silicon die. This integration reduces external component count and simplifies board layout compared to discrete Z80 implementations.
