Z84C1008PEC

Specialized Overview

The Z84C1008PEC is a CMOS Direct Memory Access (DMA) controller manufactured by Zilog. It operates on a single 5V power supply and utilizes the Z80 bus architecture for data transfer management. The component is housed in a 40-pin Plastic Dual In-line Package (PDIP) designed for through-hole mounting. It supports DMA clock frequencies up to 8 MHz, enabling efficient high-speed data movement between memory and peripheral devices without continuous CPU intervention.

Specialized Feature Summary

• Provides dedicated hardware support for managing direct memory access operations within embedded systems.
• Integrates with the Z80 microprocessor family to facilitate seamless data transfer protocols.
• Utilizes CMOS technology to ensure reliable performance under standard industrial voltage conditions.

Specialized Applications

• Data acquisition systems requiring automated memory buffering
• Industrial control interfaces utilizing Z80-based architectures
• Communication equipment needing high-throughput data handling

Specialized Procurement Notes

Verify component authenticity due to End-of-Life status. Confirm package integrity and pin alignment against original specifications. Check for RoHS compliance requirements as older batches may not meet current environmental standards. Validate supplier documentation for traceability and storage history to prevent moisture damage.

Specialized Selection Notes

Select this component only when integrating with legacy Z80-based designs requiring specific DMA timing characteristics. Ensure the system board supports 40-pin DIP footprints. Consider signal integrity and noise immunity for the 8 MHz clock input. Evaluate thermal dissipation capabilities within the enclosure design for continuous operation.

Specialized Part Context

This device belongs to the Z84C10 series of specialized interface controllers developed by Zilog. It complements other Z80 ecosystem components like the Z84C42 I/O controller. The series was designed to provide robust peripheral management solutions for industrial and commercial applications before transitioning to newer integrated processor technologies.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available. As an End-of-Life product, no direct functional equivalents are listed in official manufacturer documentation. Designers must evaluate custom PCB adaptations or verify compatibility with generic DMA controllers if redesigning the system architecture.
