Z85C3008PEG

Specialized Overview

The Z85C3008PEG is a CMOS Serial Communications Controller (SCC) designed for nonmultiplexed bus microprocessors. It features two independent full-duplex channels supporting data rates up to 4.1 Mbps, each with dedicated Baud Rate Generators and Digital Phase-Locked Loops. The device supports asynchronous, synchronous, and SDLC/HDLC protocols with programmable data encoding. It operates within a voltage range of 4.5 V to 5.5 V and utilizes a 40-pin Dual In-line Package (PDIP).

Specialized Feature Summary

• Dual-channel architecture with independent clock recovery mechanisms.
• Multiprotocol support including asynchronous, synchronous, and SDLC/HDLC modes.
• Integrated CRC generation and checking capabilities.
• Enhanced DMA support with status FIFO and byte counters.

Specialized Applications

• Serial communication interfaces for nonmultiplexed CPU systems.
• High-speed data transfer applications utilizing DMA controllers.
• T1 digital trunk implementations.

Specialized Procurement Notes

Verify the specific suffix 'PEG' against official documentation to confirm package type and temperature rating. Confirm end-of-life status prior to design-in, as availability may be restricted.

Specialized Selection Notes

Select this component when interfacing with nonmultiplexed address/data buses. Ensure system requirements align with the 4.5 V to 5.5 V supply voltage and TTL-level signal compatibility.

Specialized Part Context

This part belongs to the Z85C30 series, optimized for nonmultiplexed bus architectures. It maintains pin and software compatibility with previous NMOS versions while offering improved CMOS performance and noise immunity.

Specialized Replacement Considerations

Z80C30 variants are available for multiplexed bus systems. Verify functional equivalence if substituting with other SCC family members.
