Z85C3016VEG

Specialized Overview

The Z85C3016VEG is a CMOS Serial Communications Controller (SCC) featuring two independent full-duplex channels. It supports data rates up to 4.1 Mbps and operates with a maximum clock frequency of 16.384 MHz. The device utilizes a 44-pin PLCC package and requires a supply voltage between 4.5V and 5.5V. Each channel includes dedicated Baud Rate Generators, Digital Phase-Locked Loops, and crystal oscillators for clock recovery. It provides multiprotocol support including asynchronous, synchronous, SDLC, and HDLC modes.

Specialized Feature Summary

• Dual-channel architecture with independent baud rate generators and digital phase-locked loops
• Multiprotocol operation supporting asynchronous, synchronous, SDLC, and HDLC formats
• Optimized for nonmultiplexed bus microprocessors with direct CPU interface
• Integrated status FIFO and byte counter for enhanced DMA transfer support

Specialized Applications

• High-speed serial communication interfaces in embedded systems
• Modem control applications requiring hardware flow control
• SDLC/HDLC frame processing for network protocols
• Data acquisition systems utilizing DMA for bulk transfers

Specialized Procurement Notes

Verify the specific suffix 'VEG' against the manufacturer's current ordering information to confirm lead-free compliance and package type. Confirm availability as this component series may have discontinuation notices. Ensure the design supports the required 4.5V to 5.5V operating voltage range and 44-pin PLCC footprint.

Specialized Selection Notes

Select the Z85C3016VEG when interfacing with nonmultiplexed bus architectures requiring high-performance serial I/O. Compare against the Z80C30 variant if a multiplexed bus interface is necessary. Consider the 16.384 MHz speed grade for applications demanding higher throughput than the standard 10 MHz or 8.5 MHz variants.

Specialized Part Context

This component belongs to the Zilog Z85C30 family of CMOS Serial Communications Controllers. It serves as an advanced successor to earlier NMOS SCC devices, offering improved AC timing and lower power consumption. The Z85C30 series is designed to replace legacy controllers while maintaining software compatibility.

Specialized Replacement Considerations

The Z80C30 series offers pin-compatible alternatives for multiplexed bus systems. Verify functional equivalence regarding interrupt handling and register mapping before substitution.
