Z84C2006PEG

Specialized Overview

The Z84C2006PEG is a CMOS Parallel I/O Controller designed for the Z80 microprocessor family. It functions as a programmable, dual-port device providing a TTL-compatible interface between peripheral devices and the Z80 CPU. The component supports flexible configuration of input/output lines through software control. Key electrical specifications include an operating supply voltage range of 4.5V to 5.5V and a maximum clock frequency of 4 MHz. The device is housed in a 16-pin Plastic Dual In-line Package (PDIP) with a standard pin count compatible with legacy Z80 system architectures.

Specialized Feature Summary

• Provides a direct hardware interface between Z80 microcomputer systems and external peripheral devices
• Features a programmable dual-port architecture allowing independent configuration of data direction registers
• Ensures signal compatibility with TTL logic levels for robust integration into existing digital circuits

Specialized Applications

• Parallel communication interfaces in industrial automation controllers
• Peripheral expansion modules for legacy Z80-based embedded systems
• Digital I/O handling in test and measurement equipment

Specialized Procurement Notes

Verify the specific suffix 'PEG' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the source document explicitly lists this part number variant. Cross-reference the pinout diagram with the target PCB footprint to prevent installation errors due to package variations within the same product family.

Specialized Selection Notes

Select this component when a dedicated parallel I/O controller is required for Z80-based designs. It serves as a complementary peripheral to the Z84C00 CPU and Z84C30 timer. Consider the 4 MHz speed limit and PDIP packaging constraints during system design. Verify that the application does not require serial communication capabilities, which are handled by separate SIO components.

Specialized Part Context

The Z84C2006 belongs to the Zilog Z80 Peripheral Family, alongside the Z84C00 CPU and Z84C30 CTC. This series forms a complete ecosystem for building Z80-based microcomputer systems. The PIO specifically handles general-purpose parallel data transfer, reducing the CPU's overhead for I/O management tasks compared to bit-banging methods.

Specialized Replacement Considerations

Publicly confirmed substitutes include the STMicroelectronics Z84C20 and NTE Electronics NTE3881. Verify functional equivalence and pin compatibility before substitution. Other variants such as the Z84C2006PEC or Z84C2006VEC may offer different package options but share identical core functionality.
