Z0844104PSC

Overview

The Z0844104PSC is a dual-channel serial I/O controller from the Z80-SIO/1 family, manufactured by Zilog. It utilizes NMOS technology and operates at a maximum clock frequency of 4 MHz. The component is housed in a 40-pin Dual In-line Package (DIP) designed for through-hole mounting. This integrated circuit provides asynchronous and synchronous serial communication capabilities, serving as a versatile interface solution for microprocessor systems requiring reliable data transmission over serial links.

Feature Summary

Dual-channel serial input/output control
Z80-SIO/1 architecture compatibility
NMOS fabrication process

Applications

Asynchronous serial data transmission interfaces
Synchronous serial communication link management
Microprocessor system peripheral interfacing

Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part is listed as discontinued. Confirm package integrity and pin alignment against the 40-DIP specification. Review available datasheets for electrical characteristics prior to integration. Ensure supply chain sources provide valid traceability documentation due to the end-of-life status of the product line.

Selection Notes

Select this component when a legacy Z80-compatible serial interface is required with dual-channel support. Consider the 4 MHz operational limit and NMOS power characteristics during system design. Evaluate alternative CMOS-based SIO controllers if lower power consumption or higher speed performance is necessary for the target application environment.

Part Context

This device belongs to the Z80-SIO/1 series of serial communication controllers. It complements other Zilog interface solutions by providing dedicated hardware handling for serial protocols. The DIP-40 form factor ensures compatibility with standard through-hole PCB layouts used in industrial and embedded control systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify functional equivalence with newer serial controllers before implementation.
