Z8S18033VSC00TR

Overview

The Z8S18033VSC00TR is a microprocessor based on the Z180 architecture, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and utilizes a single core. The device supports a 5 V operating supply voltage and includes two timer/counters. It offers expanded MMU addressing up to 1 MB and integrates two asynchronous serial communication interfaces (ASCI) with baud rate generators supporting rates up to 512 Kbps. The component is housed in an 80-pin QFP package.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while providing extended instructions and faster execution speeds.
• Features two chain-linked DMA channels for high-speed memory and I/O transfers.
• Includes three low power-down modes to reduce consumption during idle states.
• Integrates on-chip interrupt controllers and wait-state generators for system flexibility.

Applications

• Embedded systems requiring backward compatibility with legacy Z80 codebases.
• Industrial control applications utilizing the integrated ASCI and DMA capabilities.
• Battery-powered devices leveraging specific low-power stop and standby modes.

Procurement Notes

Verify the exact suffix 'VSC00TR' against official Zilog documentation to confirm tape-and-reel packaging and specific temperature or voltage variants. Confirm current availability status as Z8S180 series components may have limited production runs. Ensure environmental compliance requirements match the specific manufacturing date code.

Selection Notes

Select this variant when a 33 MHz static operation speed is required within the Z180 family. Consider the 80-pin QFP package constraints for PCB layout. Evaluate if the integrated DRAM controller and MMU features meet memory expansion needs without external logic. Compare power consumption profiles across different operating modes for thermal management.

Part Context

This component belongs to the Z8S180 series, which enhances the original Z80180 design. It maintains object-code compatibility with the Z80 CPU while adding features like ESCC-like Baud Rate Generators and improved DMA channel linking. The series targets applications needing robust serial communication and efficient data transfer mechanisms.

Replacement Considerations

Check for Z8S18033FEC or Z8S18033VEG for alternative pinouts or packages. Verify if Z8L180 variants are suitable for lower voltage requirements. Consult datasheets for pin-compatible substitutes within the same manufacturer's portfolio.
