Z0853004PSC

Specialized Overview

The Z0853004PSC is a Serial Communication Controller (SCC) belonging to the Z08530 series, manufactured by Zilog. It is housed in a 40-pin Plastic Dual In-Line Package (PDIP-40) designed for through-hole mounting. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a functional clock frequency of 4 MHz. It is rated for an ambient operating temperature range from 0°C to +70°C. This component functions as a versatile interface for serial data transmission and reception.

Specialized Feature Summary

• Provides full-duplex synchronous or asynchronous serial communication capabilities
• Integrates programmable baud rate generators for flexible timing control
• Supports standard protocol implementations including HDLC and SDLC

Specialized Applications

• Computer peripheral interfaces requiring serial data handling
• Industrial control systems utilizing RS-232 or RS-422 links
• Embedded network nodes requiring reliable serial data transfer

Specialized Procurement Notes

Verify component authenticity carefully due to its discontinued status. Confirm package integrity and pin alignment upon receipt. Check datasheets for specific revision differences. Ensure compatibility with existing system voltage levels before integration into new designs.

Specialized Selection Notes

Select this part when a 4 MHz clock speed is required for serial communication tasks. Compare against the Z0853006PSC if higher throughput is needed. Verify that the PDIP-40 form factor fits the target PCB layout constraints. Consider the Z85C30 series for CMOS-based upgrades if power consumption is a critical design parameter.

Specialized Part Context

This component is part of the Z08530 family of Serial Communication Controllers. It serves as a bridge between parallel microprocessor buses and serial communication lines. The Z08530 series was widely used in early computing and industrial automation applications to manage complex serial protocols efficiently.

Specialized Replacement Considerations

The Z85C3004PSC is a CMOS-compatible replacement within the same family. Other variants like the Z0853006PSC offer higher clock speeds but maintain similar functionality.
