Z84C3008PEG

Overview

The Z84C3008PEG is a CMOS Counter/Timer Circuit (CTC) from the Zilog Z80 family, designed for high-speed digital timing applications. Operating at a maximum clock frequency of 8 MHz, this component features an 8-bit data bus width and utilizes the Z8 core architecture. It is housed in a 28-pin Plastic Dual In-line Package (PDIP) suitable for through-hole mounting. The device supports a supply voltage range of 4.5 V to 5.5 V and functions within an industrial temperature range of -40 °C to +105 °C. As a ROM-less microcontroller unit, it provides flexible I/O control capabilities without embedded program memory.

Feature Summary

• Integrated Z8 core architecture with 8-bit data bus width
• Maximum operating clock frequency of 8 MHz
• Extended industrial temperature range: -40 °C to +105 °C
• Standard 28-pin PDIP package for through-hole installation

Applications

• Digital timing and counting circuits
• System clock generation and management
• I/O controller interface support in Z80-based systems

Procurement Notes

Verify component authenticity and physical condition upon receipt, as the Z84C3008PEG is a legacy component subject to discontinuation notices. Confirm RoHS compliance status specific to the manufacturing batch, as older production runs may differ from current specifications. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage prior to soldering.

Selection Notes

Select the Z84C3008PEG when an 8 MHz synchronous timer is required for Z80-compatible architectures. The 28-pin DIP form factor is appropriate for prototyping or repair scenarios involving legacy through-hole PCBs. Consider the -40 °C to +105 °C operating range for environments requiring robust thermal stability compared to commercial-grade alternatives.

Part Context

This component belongs to the Z84C30 series of CMOS timers and support products manufactured by Zilog. It serves as a peripheral device complementing Z80 microprocessors, providing essential timing functions such as interval measurement and pulse generation. The 'PEG' suffix denotes the plastic DIP packaging variant within the broader Z84C30 product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status of many Z80-era components, direct pin-to-pin replacements may require circuit redesign or adapter solutions.
