Z85C3010VSG

Specialized Overview

The Z85C3010VSG is a CMOS Serial Communications Controller (SCC) from the Z85C30 family, designed for nonmultiplexed bus microprocessors. It features two independent full-duplex channels supporting data rates up to 4.1 Mbps. Each channel includes a dedicated crystal oscillator, Baud Rate Generator (BRG), and Digital Phase-Locked Loop (DPLL). The device supports asynchronous, synchronous byte-oriented, and bit-oriented protocols including SDLC/HDLC. It operates within a voltage range of 4.5 V to 5.5 V and utilizes a 44-pin PLCC package.

Specialized Feature Summary

• Dual-channel architecture with independent clock recovery mechanisms
• Multiprotocol support for asynchronous, synchronous, and SDLC/HDLC modes
• Integrated status FIFO and byte counter for DMA efficiency
• Optimized interface for nonmultiplexed address/data buses

Specialized Applications

• High-speed serial data transfer in industrial control systems
• SDLC/HDLC network interface implementations
• T1 digital trunk communication equipment
• Peripheral interfaces for diskette or tape drive controllers

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Ensure storage conditions meet humidity requirements to prevent damage before reflow processes.

Specialized Selection Notes

Select this model when interfacing with nonmultiplexed bus architectures requiring high-performance serial communication. Compare against Z80C30 variants if multiplexed bus compatibility is required. Evaluate power consumption and noise immunity benefits inherent to the CMOS process over older NMOS alternatives.

Specialized Part Context

This component belongs to the Zilog SCC family, introduced as a CMOS evolution of earlier NMOS designs. It maintains pin and software compatibility with legacy parts while offering enhanced performance and lower power consumption. The Z85C30 variant specifically targets systems utilizing nonmultiplexed address and data buses.

Specialized Replacement Considerations

Z80C3010VSG serves as a functional alternative for multiplexed bus applications. Verify bus type compatibility before substitution. Other Z85C30 speed grades may be interchangeable if timing constraints allow.
