Z84C4108PEG

Specialized Overview

The Z84C4108PEG is an I/O controller interface IC from the Zilog Z84C4108 series, designed for serial communication applications. It operates on a single 5V power supply and supports a maximum clock frequency of 8 MHz. The device features an 8-bit data bus width and is housed in a 40-pin DIP package suitable for through-hole mounting. It functions within an industrial temperature range of -40°C to +100°C. This component integrates serial input/output capabilities, supporting multiple communication protocols including asynchronous, synchronous byte, HDLC, SDLC, X.25, and BISYNC modes.

Specialized Feature Summary

• Integrated serial I/O controller with dual-channel capability
• Supports multiple synchronous and asynchronous communication protocols
• Compatible with Z80 bus architecture for system integration
• Industrial-grade temperature rating for extended environmental operation

Specialized Applications

• Serial communication interface modules
• Z80-based embedded systems
• Industrial control equipment requiring robust I/O handling
• Data acquisition systems with serial peripheral connections

Specialized Procurement Notes

Verify RoHS compliance status carefully as documentation indicates detailed requirements rather than simple certification. Confirm current availability status since some distributors list this part as discontinued or out of stock. Check for product change notifications regarding manufacturing source updates. Ensure the specific suffix PEG matches the required plastic DIP package variant for your PCB layout constraints.

Specialized Selection Notes

Select this component when a dedicated serial I/O controller is needed for Z80-compatible architectures. Compare against the Z84C4008PEG if lower speed requirements allow for cost optimization. Consider the Z84C4208PEC if different pinout or feature sets are acceptable. Verify that the 8MHz clock requirement aligns with your system's timing specifications and that the 40-pin DIP package fits your assembly process.

Specialized Part Context

This part belongs to the Z84C4108 family of CMOS serial I/O controllers manufactured by Zilog. These devices are specialized interface ICs designed to handle complex serial communication tasks without burdening the main processor. The Z84C4108 series typically offers enhanced protocol support compared to earlier generations, making it suitable for legacy Z80 systems requiring modern serial connectivity standards.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers include Z84C4008PEG and Z84C4208PEG. Verify functional equivalence regarding protocol support and pin compatibility before substitution. Note that some variants may have different RoHS statuses or operating temperature ranges.
