Z84C4306FEG

Specialized Overview

The Z84C4306FEG is a Serial Input/Output Controller (SIO) from the Zilog Z8 family, designed for CMOS applications. It operates at a maximum clock frequency of 6 MHz and supports an 8-bit data bus width. The device functions within a supply voltage range of 0 V to 5 V. It is rated for industrial temperature conditions, with a minimum operating temperature of -40°C and a maximum of +100°C. The component utilizes a DIP-40 through-hole package and exhibits humidity sensitivity. This integrated circuit serves as an I/O controller interface, integrating serial communication capabilities into a single chip.

Specialized Feature Summary

• Integrates serial input/output control functions within a single CMOS IC
• Supports standard 8-bit data bus architecture for microprocessor interfacing
• Operates reliably across extended industrial temperature ranges

Specialized Applications

• Serial communication interface design in embedded systems
• I/O controller integration for Z80-based microcomputer architectures
• Industrial control systems requiring robust serial data handling

Specialized Procurement Notes

This component is classified as End-of-Life (EOL). Verification of availability requires checking authorized distributors for remaining stock or surplus market sources. Ensure that any sourced units match the original ZiLOG manufacturing specifications and package type. Confirm RoHS compliance status and humidity sensitivity level before procurement to meet storage and assembly requirements.

Specialized Selection Notes

Select this part only if compatibility with the Z84C4306 series is required for legacy system maintenance. Verify that the DIP-40 through-hole package fits the target PCB layout. Consider the 6 MHz speed limit and 5 V supply requirement when designing power and clock circuits. Evaluate alternative SIO components if new designs are permitted, as this specific model is discontinued.

Specialized Part Context

The Z84C4306FEG belongs to the Z84C4306 series of Serial Input/Output Controllers produced by Zilog. These devices were widely used in early microcomputer systems to provide asynchronous serial communication ports. The 'FEG' suffix typically denotes the specific package variant and temperature grade within the broader product line, distinguishing it from surface-mount or different thermal rating versions.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements may require verification against specific application requirements. Consult Zilog archives or authorized channel partners for potential obsolescence management options.
