Z0853008VSC00TR

Specialized Overview

The Z0853008VSC00TR is a Serial Communication Controller (SCC) belonging to the Z08530 series, manufactured by Zilog. It operates within a supply voltage range of 4.75 V to 5.25 V and supports clock frequencies up to 8 MHz. The device is housed in a 44-PLCC surface-mount package with J-leads. It functions as a dual-channel serial I/O controller capable of handling asynchronous, synchronous byte, HDLC, SDLC, X.25, BISYNC, and extended synchronous protocols. The component is designed for industrial temperature ranges and includes modem control I/Os usable as general-purpose I/Os.

Specialized Feature Summary

• Dual-channel serial communication architecture supporting multiple standard protocols including HDLC and X.25.
• Integrated FIFO buffer providing status management for ten frames.
• Configurable data encoding and decoding methods such as NRZ, NRZI, and Manchester coding.
• Modem control interface lines available for general-purpose input/output applications.

Specialized Applications

• Network interface controllers requiring HDLC or SDLC protocol support.
• Industrial communication systems utilizing X.25 or BISYNC standards.
• Embedded serial port expansion modules for microcontroller-based designs.

Specialized Procurement Notes

Verify the specific suffix '00TR' against official Zilog documentation to confirm tape-and-reel packaging and any functional distinctions from standard tube-packaged variants like the Z0853008VSC. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement, as legacy components may have specific handling constraints.

Specialized Selection Notes

Select this component when a dedicated SCC is required for complex protocol handling rather than simple UART functionality. Ensure the design accommodates the 44-pin PLCC footprint and 5V logic levels. Consider the 8 MHz maximum clock speed relative to the desired baud rates and compare against newer integrated solutions if pin count or power consumption is a critical constraint.

Specialized Part Context

This part is a member of the Z08530 family of Serial Communication Controllers, which were widely used in early computing and telecommunications equipment. The Z08530 series provides hardware-assisted protocol processing, reducing CPU overhead compared to software-driven bit-banging implementations. It serves as a bridge between parallel microprocessor buses and serial transmission lines.

Specialized Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. Engineering changes should be evaluated based on pin compatibility and protocol support. Consult Zilog or Littelfuse technical support for current obsolescence notices and recommended modern alternatives.
