Z8S18033VSC

Overview

The Z8S18033VSC is a static microprocessor based on the Z180 architecture, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus and is housed in an 80-pin QFP package. The device supports a 5 V supply voltage and operates within a commercial temperature range of 0°C to +70°C. It includes two DMA channels, two UARTs, and two timers.

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 two enhanced asynchronous serial communication interfaces (ASCI) with FIFO buffers.
• Offers multiple low-power-down modes to reduce energy consumption during idle states.

Applications

• Industrial control systems requiring Z80 compatibility
• Embedded applications needing extended memory addressing
• Systems utilizing direct memory access for data throughput

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment prior to installation. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet. Validate that the specific suffix corresponds to the required packaging and temperature grade for your design.

Selection Notes

Select this variant when a 33 MHz processing speed is required alongside standard 5 V logic levels. The 80-pin QFP package is suitable for surface-mount assembly. Consider the extended MMU capabilities if applications exceed 64 KB addressable space. Verify thermal management requirements for the commercial temperature range.

Part Context

This component belongs to the Z8S180 family, which enhances the original Z80180 design. It maintains backward compatibility with existing Z80 software while adding features like clock doubling and reduced power consumption. The family supports various packaging options including PLCC and DIP.
