Z85C3016VSC

Specialized Overview

The Z85C3016VSC is a CMOS Serial Communications Controller (SCC) from the Z85C30 family, designed for nonmultiplexed bus microprocessors. It features two independent full-duplex channels operating at a maximum clock frequency of 16 MHz. The device supports asynchronous, monosync, bisync, and SDLC/HDLC protocols with data rates up to 5 Mbps. Each channel accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop. It utilizes a 4-byte transmit FIFO and an 8-byte receive FIFO per channel. The component is housed in a 44-pin PLCC package and operates within a temperature range of 0°C to +70°C.

Specialized Feature Summary

• Dual full-duplex serial communication channels with integrated clock recovery mechanisms
• Support for multiple protocol formats including asynchronous, bisync, and HDLC modes
• On-chip FIFO buffers to reduce CPU overhead during data transfers
• Hardware support for CRC error detection and various encoding schemes

Specialized Applications

• Implementation of serial networking systems requiring multi-protocol support
• Integration into embedded controllers utilizing nonmultiplexed bus architectures
• Designs requiring high-performance asynchronous or synchronous serial data handling

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific lot codes and manufacturing dates against current inventory records. Ensure proper handling procedures are followed given the moisture sensitivity classification associated with this plastic leaded chip carrier package type.

Specialized Selection Notes

Select the Z85C3016VSC when a nonmultiplexed interface is required alongside dual-channel capability. Compare against multiplexed variants like the Z80C30 series if address/data line sharing is necessary. Evaluate the 16 MHz speed requirement against lower-frequency options such as the 10 MHz variant to optimize power consumption while meeting throughput needs.

Specialized Part Context

This component belongs to the Zilog Z85C30 family of Serial Communications Controllers. It serves as the enhanced CMOS successor to earlier NMOS versions, offering pin compatibility for easier upgrades. The Z85C30 series is distinct from the Z80C30 series primarily by its support for nonmultiplexed bus interfaces, making it suitable for modern microprocessor designs that do not share address and data lines.

Specialized Replacement Considerations

The Z8523016VSC is a documented equivalent within the same product family, offering similar functionality but potentially differing in specific FIFO configurations or minor feature sets. Verify electrical characteristics and pinout compatibility before substitution.
