Z80C3010VSC

Specialized Overview

The Z80C3010VSC is a CMOS Serial Communications Controller (SCC) from the Z80C30 series, designed for high-speed serial data transmission. It features two independent full-duplex channels capable of operating at clock frequencies up to 10 MHz with data rates reaching 4.1 Mbps. The device supports multiple communication protocols including asynchronous, synchronous, and SDLC/HDLC modes. It integrates programmable baud rate generators, digital phase-locked loops for clock recovery, and enhanced DMA support with status FIFOs. The component is housed in a 68-pin PLCC package and operates within a commercial temperature range of 0°C to +70°C.

Specialized Feature Summary

• Dual-channel architecture providing independent full-duplex serial communication paths
• Support for diverse protocol modes including asynchronous, synchronous, and SDLC/HDLC with automatic frame control
• Integrated clock management featuring programmable baud rate generators and digital phase-locked loops
• Enhanced direct memory access capabilities utilizing status FIFOs and byte counters for efficient data handling

Specialized Applications

• High-speed serial data links requiring protocol flexibility
• SDLC/HDLC network interface implementations
• Embedded systems needing robust UART or SCC functionality
• Industrial communication modules operating in commercial environments

Specialized Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices or production discontinuation updates as this model may be subject to lifecycle changes. Ensure proper ESD handling procedures are followed during storage and installation.

Specialized Selection Notes

Select the Z80C3010VSC when dual-channel serial communication is required with support for complex protocols like SDLC/HDLC. Compare against the Z80C3010VSG if a 44-pin PLCC package is preferred instead of the 68-pin variant. Consider the Z85C3010VEC for applications requiring extended industrial temperature ranges. Verify bus compatibility and voltage levels match the target system design requirements.

Specialized Part Context

This component belongs to the Zilog Z80C30 family of CMOS Serial Communications Controllers. It serves as an upgrade to earlier NMOS versions, offering pin compatibility while improving performance and power efficiency. The Z80C30 series is optimized for use with multiplexed bus microprocessors, distinguishing it from the Z85C30 which targets non-multiplexed buses. This specific part number denotes the 10 MHz version in a 68-pin PLCC package.

Specialized Replacement Considerations

The Z80C3010VSG is a functional alternative within the same series but utilizes a 44-pin PLCC package rather than the 68-pin configuration. The Z85C3010VEC offers similar functionality but is designed for non-multiplexed buses and supports an extended temperature range. Direct pin-to-pin replacement is not possible between the 44-pin and 68-pin variants without PCB redesign.
