Z0844206PSC

Overview

The Z0844206PSC is a serial I/O controller manufactured by Zilog, designed for Z80 bus compatibility. It features two independent serial channels with a maximum data rate of 0.25 MBps. The component utilizes NMOS technology and operates at a clock frequency of 6 MHz. It is housed in a 40-pin PDIP package suitable for through-hole mounting. The device functions as a communication controller without DMA channel support or boundary scan capabilities.

Feature Summary

Dual-channel serial input/output management
Z80 microprocessor bus compatibility
NMOS semiconductor technology implementation

Applications

Serial communication interface design
Z80-based system peripheral integration
Industrial control data transmission

Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity and pin alignment prior to installation. Check datasheet revisions for electrical characteristics. Ensure supply chain sources provide valid manufacturer documentation. Validate environmental compliance requirements against project specifications.

Selection Notes

Select this component for legacy Z80 architecture systems requiring dual serial ports. Consider the 6 MHz operational limit when designing clock circuits. Evaluate NMOS power consumption against modern CMOS alternatives. Verify 40-pin DIP footprint availability in target PCB layout. Assess obsolescence risks for long-term production planning.

Part Context

This part belongs to the Zilog SIO/2 family of serial controllers. It complements other Z80 peripherals like the Z0803606PSC counter IC. The Z0844206PSC provides essential serial connectivity for embedded applications. It shares packaging similarities with the Z0847006PSG UART but differs in protocol support.

Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. The component status is listed as discontinued. Designers should evaluate equivalent functional blocks from current manufacturers. Legacy system maintenance may require direct sourcing from specialized distributors.
