Z8018006VSG

Overview

The Z8018006VSG is an 8-bit microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 6 MHz with a single core and an 8-bit data bus width. The device utilizes SRAM storage type and includes 64 kB of data RAM size. It features two timers/counters and supports SCI and UART interface types. The component is housed in a PLCC-68 package designed for surface mount installation. It functions within a voltage range of 5 V and operates between 0 °C and +70 °C.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating reduced system costs through integrated I/O devices such as DMA, UART, and timer channels.
• Includes on-chip interrupt controllers, three wait-state generators, an oscillator/generator, and expanded MMU addressing capabilities up to 1 MB.
• Features two DMA channels and two asynchronous serial communication interface (ASCI) channels with programmable baud rate generators.

Applications

• Embedded systems requiring Z80 code compatibility with integrated peripheral management
• Industrial control applications utilizing on-chip DMA and timer resources
• Serial communication interfaces using dual ASCI channels

Procurement Notes

Verify the specific suffix 'VSG' against official documentation to confirm lead-free environmental compliance and package type accuracy. Confirm that the 6 MHz speed grade matches the design requirements. Check current lifecycle status as discontinuance notifications may apply to this family. Ensure moisture sensitivity handling procedures are followed during assembly.

Selection Notes

Select this variant when a 6 MHz operating speed is sufficient for the application logic. The PLCC-68 package requires surface mount technology implementation. Consider the 0 °C to +70 °C temperature range limits for environmental suitability. Verify that the 64 kB internal RAM meets memory capacity needs without external expansion.

Part Context

This component belongs to the Z80180 series of enhanced microprocessors. The series combines the Z80 CPU core with various system resources including DMA controllers, ASCI ports, and programmable reload timers. The Z8018006VSG represents the 6 MHz speed grade within the commercial temperature range offering.

Replacement Considerations

Z8018006PEC: Same electrical specifications but in a DIP-64 package.
