Z84C4406VEC

Specialized Overview

The Z84C4406VEC is a specialized I/O controller interface integrated circuit manufactured by Zilog. It belongs to the Z80 series and is designed for embedded applications requiring dedicated input/output management. The device operates on a single 5V power supply and features a 44-pin PLCC surface-mount package. It supports an industrial temperature range from -40°C to +100°C. The component is classified as a specialized interface IC, distinct from general-purpose microprocessors, focusing on hardware-level I/O control functions within system architectures.

Specialized Feature Summary

• Dedicated I/O controller functionality for specialized interface tasks
• Surface-mount PLCC-44 packaging for compact board integration
• Industrial-grade thermal stability across extended temperature ranges

Specialized Applications

• Embedded systems requiring dedicated hardware I/O control
• Industrial equipment with specific interface requirements
• Legacy Z80-based system peripheral expansion

Specialized Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to surplus stock or third-party distributors. Verification of authenticity and physical condition is critical due to the age of the product. Buyers should confirm the specific revision level and ensure compatibility with existing design constraints before procurement.

Specialized Selection Notes

Engineers selecting this part must account for its discontinued status and limited long-term supply chain support. The 44-pin PLCC form factor requires specific footprint verification during PCB layout. Alternative solutions should be evaluated if new production longevity is required, as replacement components may necessitate schematic and layout modifications.

Specialized Part Context

The Z84C4406VEC is part of Zilog's broader Z84C44 family of specialized interface controllers. These devices complement the company's Z80 microprocessor ecosystem by providing dedicated hardware support for complex I/O operations. The component represents a niche solution for systems where software-driven I/O management is inefficient or insufficient for real-time requirements.
