Z8S18010FEG

Overview

The Z8S18010FEG is an 8-bit microprocessor IC from the Z180 series, manufactured by Zilog. It features a single core with a maximum clock speed of 10 MHz and operates within a voltage range of 4.5 V to 5.5 V. The device is housed in an 80-pin QFP package and supports surface mount mounting. It includes on-chip interfaces such as ASCI, CSIO, and UART, along with DRAM controllers. The operating temperature range is specified from -40°C to +100°C.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while offering extended instructions and faster execution speeds.
• Integrated two chain-linked DMA channels for high-speed data transfers between memory and I/O devices.
• Includes two enhanced UARTs with ESCC-like Baud Rate Generators supporting asynchronous data transfer rates up to 512 Kbps.
• Features three low power-down modes including Stop Mode and Standby Mode to reduce power consumption.

Applications

• Embedded systems requiring backward compatibility with Z80 architecture
• Industrial control applications utilizing on-chip timers and interrupt controllers
• Communication interfaces using dual ASCI channels with FIFO buffers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for Product Change Notifications regarding assembly origin or obsolescence. Ensure handling procedures account for Moisture Sensitivity Level 3 requirements during storage and reflow soldering processes.

Selection Notes

Select this component when Z80 instruction set compatibility is required alongside enhanced peripheral integration. Consider the 80-QFP package for surface mount designs needing extensive I/O capabilities. Evaluate the 10 MHz speed against system timing requirements and ensure voltage levels match the 5V operational specification.

Part Context

This part belongs to the Z8S180 family, which enhances the original Z80180 design with improved power management and EMI noise reduction. The Z180 architecture combines a high-performance CPU core with integrated system resources like MMU and DMA controllers, serving as a bridge between legacy Z80 systems and modern embedded requirements.

Replacement Considerations

Z8S18010FSG: Similar 10 MHz Z180 processor in 80-QFP package but rated for commercial temperature range (0°C to +70°C) instead of industrial range.

FAQ

Does the Z8S18010FEG support full backward compatibility with existing Z80 software?

Yes, the Z8S180/Z8L180 provides full object-code compatibility with existing ZiLOG Z80 devices while adding a superset of instructions.

What is the function of the chain-linked DMA channels?

The two DMA channels can be linked to allow nonstop DMA operation between channels when they take requests from the same peripheral device.
