Z85C3008VEC

Specialized Overview

The Z85C3008VEC is a dual-channel, full-duplex Serial Communications Controller (SCC) manufactured by Zilog. It operates within a supply voltage range of 4.5V to 5.5V and supports processing speeds up to 5 Mbps. The device features two independent channels, each equipped with its own crystal oscillator, baud rate generator, and digital phase-locked loop for clock recovery. It utilizes a 44-pin PLCC package and functions across an operating temperature range of -40°C to +105°C.

Specialized Feature Summary

• Dual independent full-duplex communication channels
• Supports multi-protocol formats including asynchronous, bisync, and SDLC/HDLC
• Integrated FIFO buffers for transmit and receive operations
• On-chip baud rate generation and digital phase-locked loop

Specialized Applications

• Serial networking implementations
• TDMA data link control systems
• General-purpose serial I/O controller interfaces

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package type and temperature rating. Check current availability status as this series may be subject to discontinuation notices. Ensure compliance with relevant environmental regulations prior to integration into final assemblies.

Specialized Selection Notes

Select this model when a dual-channel SCC with extended industrial temperature ratings is required. Compare against the Z85230 series if enhanced DMA support or different FIFO depths are necessary. Verify bus compatibility requirements against the target microprocessor architecture before finalizing the design choice.

Specialized Part Context

This component belongs to the Z85C30 family of CMOS Serial Communications Controllers. It is software and pin-compatible with the Z80C30 series but optimized for non-multiplexed bus architectures. The device represents a standard solution for integrating high-performance serial communication capabilities into embedded systems requiring robust protocol handling.

Specialized Replacement Considerations

The Z8523008VEC serves as a functional substitute within the same package. Verify FIFO depth differences and DMA feature sets during transition. Cross-reference the Z80C3008VEC only if multiplexed bus timing constraints apply.
