Z8523010PSC

Specialized Overview

The Z8523010PSC is a nonmultiplex Serial Communication Controller (SCC) from the ZiLOG enhanced dual SCC family. It features two full-duplex channels and supports processing speeds up to 5 Mbps. The device accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 40-pin DIP package.

Specialized Feature Summary

• Enhanced dual full-duplex serial communication architecture
• Integrated baud rate generation and clock control per channel
• Support for multi-protocol formats including async, bisync, and SDLC/HDLC
• Hardware error detection using CRC-16 or CRC-CCITT

Specialized Applications

• Network interface implementations requiring asynchronous serial protocols
• Synchronous data link control (SDLC/HDLC) terminal applications
• Bisync protocol communication systems
• Embedded controller interfaces with high-speed serial requirements

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older manufacturing runs may differ. Check for specific lot codes regarding moisture sensitivity levels if long-term storage is anticipated before assembly.

Specialized Selection Notes

Select this part when dual independent serial channels are required without multiplexing overhead. Compare against the Z85C30 series for standard performance needs or the Z80230 series if multiplexed bus interfaces are preferred. Ensure voltage levels match the target system logic requirements.

Specialized Part Context

This component belongs to the Z85230 enhanced dual SCC family, designed to reduce CPU overhead compared to earlier generations. It serves as a bridge between parallel microprocessor buses and serial transmission lines, offering integrated FIFO buffers and DMA capabilities to streamline data transfer operations.

Specialized Replacement Considerations

The Z8523010PEC is a ceramic equivalent in a DIP-40 package. The Z8523010VEC and Z8523010VSC offer surface mount PLCC-44 options. Verify pin compatibility and thermal characteristics when transitioning between package types.
