Z8S18033FEG

Overview

The Z8S18033FEG is a static microprocessor unit based on the Z180 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 33 MHz with a single 8-bit core. The device utilizes an 80-pin Quad Flat Package (QFP) for surface mount installation. It functions within a standard voltage range of 5.0V and supports an industrial operating temperature range from 0°C to +70°C. The component provides full backward compatibility with existing Z80 CPU code while offering extended instruction sets and enhanced peripheral integration.

Feature Summary

• Code compatible with ZiLOG Z80 CPU with extended instructions
• Two chain-linked DMA channels for high-speed data transfer
• On-chip interrupt controllers and three wait-state generators
• Enhanced asynchronous serial communication interfaces with FIFO buffers

Applications

• Industrial control systems requiring Z80 compatibility
• Embedded applications needing low power-down modes
• Systems utilizing expanded MMU addressing up to 1 MB
• Data acquisition setups using on-chip timers and counters

Procurement Notes

Verify the specific suffix 'FEG' against official Zilog documentation to confirm package type and temperature rating. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check for Product Change Notifications or End-of-Life announcements prior to procurement to ensure long-term availability.

Selection Notes

Select this component when a Z80-compatible processor with integrated peripherals is required. Ensure the design accommodates the 80-QFP package dimensions. Verify that the system clock requirements align with the 33 MHz maximum speed. Consider the 5V I/O voltage levels for interface compatibility with other system components.

Part Context

This part belongs to the Z8S180 series, which enhances the original Z80180 model. The series offers faster execution speeds, reduced power consumption, and EMI noise reduction. It integrates memory management, DMA, and serial communication capabilities into a single chip, serving as a drop-in replacement for legacy Z80 designs with added functionality.
