Z16C3010VSC

Overview

The Z16C30VSC is a CMOS Universal Serial Controller (USC) manufactured by Zilog, packaged in a 68-pin PLCC. It features two independent full-duplex channels supporting data transfer rates up to 10 Mbps. Each channel includes dual baud rate generators and a digital phase-locked loop for clock recovery. The device provides 32-byte FIFOs for both receiver and transmitter operations. It supports asynchronous, synchronous byte-oriented, and bit-oriented protocols with programmable bus interfaces compatible with the 680X0 and 8086 families. Operating voltage ranges from 4.5 V to 5.5 V, with an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel architecture with independent control structures
• Support for multiple serial communication protocols including HDLC/SDLC and Bisync
• Integrated DMA interface for high-speed data transfers
• Programmable bus interface supporting 8-bit or 16-bit configurations

Applications

• Serial-to-parallel conversion in multiprocessor systems
• High-speed data communications peripherals
• Modem control applications requiring general-purpose I/O flexibility

Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence. Confirm package integrity and moisture sensitivity levels prior to soldering. Ensure compatibility with existing system voltage requirements and bus timing specifications during integration planning.

Selection Notes

Select the Z16C30VSC when dual-channel serial communication with protocol flexibility is required. Consider the 68-pin PLCC package constraints for PCB layout. Evaluate bus interface compatibility with target microprocessors before finalizing design choices.

Part Context

The Z16C30 belongs to Zilog's USC family, designed for versatile serial data handling. It serves as a bridge between parallel processor buses and serial communication lines, offering extensive protocol support and high throughput capabilities for embedded systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the Z16C30 series. Verify electrical characteristics and protocol support match original requirements when considering alternative components.
