Z84C4008PEC

Specialized Overview

The Z84C4008PEC is a CMOS Serial I/O Controller manufactured by Zilog, belonging to the Z80 series. It operates on a single 5V supply voltage and features a 40-pin Plastic Dual In-line Package (PDIP). The device supports two serial channels with a maximum data transfer rate of 0.25 MBps. It accommodates multiple communication protocols including ASYNC, BIT, SYNC BYTE, SYNC HDLC, SYNC SDLC, X.25, and BISYNC. The component is designed for through-hole mounting and functions as an I/O controller interface.

Specialized Feature Summary

• Supports dual-channel serial input/output operations
• Compatible with standard Z80 bus architecture
• Handles various synchronous and asynchronous communication protocols

Specialized Applications

• I/O controller interface systems
• Serial communication protocol implementation
• Embedded system peripheral control

Specialized Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity upon receipt. Check datasheet revisions for pinout consistency. Validate RoHS compliance requirements against project specifications. Ensure storage conditions meet moisture sensitivity level standards.

Specialized Selection Notes

Select this component for legacy Z80-based designs requiring dedicated serial I/O handling. Compare pin compatibility with existing PCB layouts. Evaluate thermal performance within the specified operating temperature range. Consider availability constraints given the discontinued status.

Specialized Part Context

This part belongs to the Z84C40 family of serial I/O controllers. It shares functional similarities with variants like Z84C4008PEG but differs in packaging and regulatory compliance. The PEC suffix indicates a specific plastic DIP configuration distinct from ceramic or surface-mount alternatives within the same product line.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with any potential alternative components before integration.
