Z84C2008PEC

Specialized Overview

The Z84C2008PEC is a CMOS Serial I/O Controller manufactured by Zilog, belonging to the Z84C40 series. It provides two independent serial communication channels within a single integrated circuit. The device supports multiple synchronous and asynchronous protocols, including HDLC, SDLC, X.25, BISYNC, and asynchronous bit/byte modes. It operates on a single 5V power supply and features an 8-bit external data bus. The component is housed in a 40-pin Dual In-line Package (DIP) designed for through-hole mounting.

Specialized Feature Summary

• Dual-channel architecture enabling simultaneous independent serial communications
• Supports diverse protocol standards including HDLC, SDLC, X.25, and BISYNC
• CMOS technology ensuring low power consumption relative to earlier generations
• Integrated baud rate generation capabilities for flexible clocking

Specialized Applications

• Serial interface modules for industrial automation systems
• Communication controllers in embedded computer architectures
• Data acquisition systems requiring multi-channel serial connectivity
• Legacy system upgrades utilizing Z80-compatible buses

Specialized Procurement Notes

Verify component authenticity due to discontinued status. Check datasheet revisions for pinout consistency with original Z84C40 specifications. Confirm package integrity as DIP-40 units may have aged. Ensure voltage levels match target system requirements before integration into new designs.

Specialized Selection Notes

Select this component when dual serial ports are required within a Z80-based environment. Compare against Z84C30 variants if only one channel is needed. Evaluate physical footprint constraints of the 40-PDIP package against available PCB real estate. Consider thermal dissipation characteristics inherent to CMOS logic families at maximum operating frequencies.

Specialized Part Context

This part is a member of the Z84C40 family, which succeeded the NMOS Z8440 series. It serves as a specialized interface controller designed to offload serial processing tasks from the main CPU. The Z84C2008PEC specifically denotes the dual-channel variant within this lineage, maintaining software compatibility with previous Z8440 implementations while offering improved CMOS performance metrics.

Specialized Replacement Considerations

Publicly confirmed substitutes include the Z84C3008PEC for single-channel applications or other Z84C40 series derivatives. Verify functional equivalence regarding protocol support and timing parameters before substitution.
