Z16C3010VSG

Overview

The Z16C30VSG 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 rates up to 10 Mbps. Each channel includes a 32-byte receive FIFO and a 32-byte transmit FIFO, along with dedicated baud rate generators and a digital phase-locked loop for clock recovery. The device operates on a single +4.5 V to +5.5 V supply with a typical current consumption of 7 mA at 5 V. It supports a bus cycle time of 110 ns and accommodates both 8-bit and 16-bit data buses via a flexible interface compatible with the 680X0 and 8086 families.

Feature Summary

• Dual-channel architecture with independent mode selection for asynchronous, synchronous byte-oriented, and bit-oriented protocols.
• Integrated hardware support for CRC generation and checking across multiple communication standards.
• Direct Memory Access (DMA) capability with separate request and acknowledge signals for each receiver and transmitter.
• Flexible bus interface allowing direct connection to microprocessors with selectable 8-bit or 16-bit widths.

Applications

• High-speed serial data communication systems requiring multi-protocol support.
• Industrial control networks utilizing HDLC, SDLC, or Bisync standards.
• Computer peripheral interfaces connecting to 680X0 or 8086-based host systems.
• Modem control applications where general-purpose I/O functionality is required.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity levels prior to soldering. Ensure storage conditions meet specified environmental requirements to maintain device integrity before assembly.

Selection Notes

Select this component when dual-channel serial communication with high throughput is required. Ensure the target system supports the necessary bus timing constraints of 110 ns. Verify that the application environment falls within the standard operating temperature range of 0°C to +70°C. Confirm package availability matches the PCB footprint design specifications.

Part Context

The Z16C30 belongs to Zilog's USC family, designed as a versatile serial-to-parallel converter. It serves as a critical interface between parallel microprocessor buses and serial transmission lines. The device integrates complex protocol handling internally, reducing external logic requirements compared to earlier discrete controller solutions.

Replacement Considerations

Consult Zilog technical documentation for verified cross-reference part numbers. Ensure any substitute maintains compatibility with the 68-pin PLCC package and supports the same voltage and timing specifications.
