Z80C3010PSG

Specialized Overview

The Z80C3010PSG is a CMOS Serial Communications Controller (SCC) designed for multiplexed bus microprocessors. It features two independent full-duplex channels supporting data rates up to 4.1 Mbps. The device includes separate crystal oscillators, baud rate generators, and digital phase-locked loops for clock recovery per channel. It supports asynchronous, synchronous, and SDLC/HDLC protocols with programmable data encoding. The component operates at a clock speed of 10 MHz and is housed in a 40-pin Dual In-line Package.

Specialized Feature Summary

• Dual-channel architecture with independent clocking and baud rate generation
• Multiprotocol support including asynchronous, synchronous, and SDLC/HDLC modes
• Integrated CRC generation and checking capabilities
• Software interrupt acknowledge and enhanced DMA support

Specialized Applications

• Serial communication interfaces for multiplexed bus systems
• SDLC and HDLC protocol implementations
• T1 digital trunk applications
• General-purpose serial data transfer peripherals

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation. Note that the Z80C3010PSG has been identified as End-of-Life (EOL) status in official revision histories. Confirm availability through authorized distributors or secondary markets if active procurement is required.

Specialized Selection Notes

Select this component when interfacing with microprocessors utilizing multiplexed address/data buses. Ensure the system design accommodates the 10 MHz clock requirement. Verify that the application benefits from the integrated DPLL and BRG features to minimize external logic requirements compared to NMOS predecessors.

Specialized Part Context

This part belongs to the Zilog SCC family, specifically optimized for multiplexed bus architectures unlike the Z85C30 which targets nonmultiplexed buses. It maintains pin and software compatibility with earlier NMOS versions while offering improved performance and lower power consumption through CMOS technology.

Specialized Replacement Considerations

Consider the Z85C30 series for nonmultiplexed bus designs. For direct replacements, verify EOL status implications and source availability. Check for updated manufacturing sites or package changes documented in Product Change Notifications.
