Z8S18033FSC00TR

Overview

The Z8S18033FSC00TR is a microprocessor based on the Z180 core, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and utilizes a ROMless architecture. The device supports a supply voltage of 5 V and operates within a commercial temperature range of 0°C to +70°C. It is housed in a 44-LQFP package with dimensions of 10x10 mm. Key integrated peripherals include two asynchronous serial communication interfaces (ASCI), two programmable reload timers, and two chain-linked DMA channels.

Feature Summary

• Code-compatible with the ZiLOG Z80 CPU while providing extended instruction sets and enhanced execution speeds.
• Integrates two asynchronous serial communication interfaces supporting baud rates up to 512 Kbps with FIFO buffers.
• Features two chain-linked DMA channels for high-speed memory-to-memory and I/O transfers.
• Includes an expanded Memory Management Unit allowing access to up to 1 MB of address space.

Applications

• Industrial control systems requiring backward compatibility with legacy Z80 software.
• Embedded applications needing low-power down modes and static operation capabilities.
• Data acquisition systems utilizing integrated DMA and timer resources.
• Communication devices employing dual UART functionality for serial data transfer.

Procurement Notes

Verify the specific suffix FSC00TR against official datasheets to confirm package type and temperature rating. Confirm RoHS compliance status as historical Zilog products may vary. Check for obsolescence notices or product discontinuation notifications prior to finalizing design-in decisions. Ensure moisture sensitivity level handling protocols are followed during assembly.

Selection Notes

Select this component when Z80 code compatibility is required alongside modern peripheral integration. Consider the 33 MHz speed for performance-critical tasks within the Z180 family. Evaluate the 44-LQFP package constraints against board layout requirements. Compare power consumption characteristics across different operating modes if battery life is a critical factor.

Part Context

This part belongs to the Z8S180 series, which enhances the original Z80180 architecture. The series offers improved power efficiency and additional I/O features compared to predecessors. It serves as a bridge between legacy Z80 ecosystems and more complex embedded requirements without necessitating a complete architectural migration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-compatibility with other Z8S180 variants based on clock speed and package differences.
