Z8523016PSC

Specialized Overview

The Z8523016PSC is a nonmultiplex Serial Communication Controller (SCC) from the Z85230 family, manufactured by ZiLOG. It features dual 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 temperature range of 0°C to +70°C and utilizes a 40-pin DIP package.

Specialized Feature Summary

• Dual full-duplex serial communication channels
• Support for multi-protocol formats including async, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop
• Integrated FIFO buffers with 4-byte transmit and 8-byte receive capacity
• Hardware error detection using CRC-16 or CRC-CCITT

Specialized Applications

• Network interface implementations requiring high-performance serial data handling
• Embedded systems utilizing asynchronous or synchronous communication protocols
• Industrial control applications operating within standard commercial temperature ranges

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older manufacturing runs may not meet current environmental standards. Ensure proper ESD protection during handling due to CMOS technology sensitivity.

Specialized Selection Notes

Select this part when dual-channel nonmultiplexed SCC functionality is required at 5 Mbps speeds. Compare against multiplexed variants like the Z85C30 series if pin count reduction is necessary. Consider the Z8523016VEC for surface mount requirements instead of the through-hole DIP package.

Specialized Part Context

This component belongs to the enhanced Z85230 family of Serial Communication Controllers. It shares architectural similarities with the Z80230 but offers specific enhancements in FIFO depth and programming ease. It serves as a bridge between microprocessors and serial network lines, reducing external logic requirements.

Specialized Replacement Considerations

Direct replacements include other Z85230 family members such as the Z8523016PEC or Z8523016VEC, depending on package preference. Cross-family substitution with Z85C3016PSC requires verification of multiplexing differences.
