Z84C4006PEG

Specialized Overview

The Z84C4006PEG is a CMOS Serial I/O Controller (SIO) from the Z84C40 series, manufactured by Zilog. It operates on a single 5V supply and supports a maximum clock frequency of 6 MHz. The device features two independent serial channels with an external data bus width of 8 bits. It is housed in a 40-pin Dual In-line Package (DIP) designed for through-hole mounting. The component supports multiple communication protocols including ASYNC, BIT, SYNC BYTE, SYNC HDLC, SYNC SDLC, X.25, and BISYNC. It functions as a dedicated interface for I/O controllers within embedded systems.

Specialized Feature Summary

• Dual-channel serial communication architecture supporting asynchronous and synchronous modes
• Integrated protocol handling for HDLC, SDLC, X.25, and BISYNC standards
• CMOS technology enabling low power consumption with standard 5V logic compatibility

Specialized Applications

• Serial communication interfaces in industrial control systems
• Data acquisition modules requiring multi-protocol support
• Embedded computer systems utilizing Z80-compatible architectures

Specialized Procurement Notes

Verify component authenticity upon receipt, as this part may be subject to obsolescence notices. Confirm that the 40-pin DIP package matches the target PCB footprint. Ensure voltage levels align with the 5V specification before integration into existing circuit designs.

Specialized Selection Notes

Select this component when dual serial ports are required within a Z80-based system. Compare against the Z84C4108 or Z84C4206 if higher clock speeds or different channel configurations are necessary. Verify that the 6 MHz limit meets the timing requirements of the specific serial peripherals involved.

Specialized Part Context

This unit belongs to the Z84C40 family of Serial I/O Controllers, which complements the Z84C00 CPU series. It provides essential serial connectivity for microcontroller applications, serving as a bridge between parallel processor buses and serial peripheral devices.

Specialized Replacement Considerations

Publicly confirmed substitutes include the Z84C4008PEG and Z84C4010PEG within the same manufacturer lineup. These variants offer similar functionality but differ in maximum operating frequencies.
