Z85C3008VSC

Specialized Overview

The Z85C3008VSC is a CMOS Serial Communication Controller (SCC) from the Z85C30 family, designed for nonmultiplex bus microprocessors. It features two independent full-duplex channels with processing speeds up to 5Mbps. The device operates within a voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. It is housed in a 44-pin PLCC package. Each channel accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop. The Z85C3008VSC includes a 1-byte transmit FIFO and a 3-byte receive FIFO per channel.

Specialized Feature Summary

• Supports multi-protocol formats including asynchronous, monosync, bisync, and SDLC/HDLC modes.
• Provides flexible data encoding options such as NRZI, FM0, FM1, and Manchester.
• Integrates on-chip clock recovery mechanisms including baud rate generators and digital phase-locked loops.
• Offers CRC-16 or CRC-CCITT error detection capabilities.

Specialized Applications

• Networking applications requiring fully integrated serial communication solutions.
• Systems utilizing nonmultiplex bus microprocessors.
• Interfaces supporting SDLC/HDLC protocol implementations.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for obsolescence notices or production change notifications that may affect availability or specifications.

Specialized Selection Notes

Select this model for designs requiring dual full-duplex channels on nonmultiplex buses. Ensure the system voltage aligns with the 4.75V to 5.25V requirement. Consider the PLCC-44 package constraints for PCB layout. Compare against Z80C30 variants if multiplexed bus support is needed instead.

Specialized Part Context

This component belongs to the Zilog Z85C30 series of Serial Communication Controllers. It is part of a broader family that includes multiplexed versions like the Z80C30 and enhanced models like the Z85230. The Z85C30 series is characterized by its CMOS technology and compatibility with standard microprocessor interfaces.

Specialized Replacement Considerations

Z85C3008VEC offers identical functionality but supports an extended industrial temperature range of -40°C to +105°C. Z80C3008VSC is pin-compatible but designed for multiplexed bus architectures rather than nonmultiplex systems.
