Z8S18033FSC

Overview

The Z8S18033FSC is a microprocessor IC based on the Z180 core, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and utilizes an 80-pin QFP package for surface mount installation. The device operates within a commercial temperature range of 0°C to +70°C and requires a 5V supply voltage. It is ROMless and includes two timer/counters.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while providing extended instructions
• Features two chain-linked DMA channels for high-speed data transfers
• Includes three on-chip wait-state generators and an on-chip oscillator
• Supports expanded MMU addressing up to 1 MB

Applications

• Embedded systems requiring backward compatibility with Z80 architecture
• Industrial control applications utilizing asynchronous serial communication
• Memory management intensive designs using expanded addressing

Procurement Notes

Verify the specific suffix FSC against the manufacturer datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm availability status as distribution listings may vary. Ensure compliance with RoHS directives if required by your system specifications before finalizing procurement.

Selection Notes

Select this component when Z80 instruction set compatibility is mandatory alongside enhanced Z180 features such as integrated DMA and UARTs. The 33 MHz speed suits applications needing higher throughput than standard Z80 variants. The 80-pin QFP package is suitable for dense surface-mount layouts.

Part Context

This part belongs to the Z8S180 series, which enhances the original Z80180 model with lower power consumption and EMI noise reduction. The series supports multiple packaging styles including PLCC, DIP, and QFP, offering flexibility for various board design constraints and thermal requirements.

Replacement Considerations

Z8S18033FSG: Different package (QFP-80 vs QFP-80, verify pinout). Z8S18033VEG: Different package (PLCC-68). Z8L18033FSC: Low power variant.
