Z8523016PEC

Specialized Overview

The Z8523016PEC is a dual-channel Serial Communication Controller (SCC) from the Z85230 family, designed for high-performance serial data transmission. It operates within a voltage range of 4.5V to 5.5V and supports processing speeds up to 5 Mbps. The device features two full-duplex channels, each capable of accommodating a crystal oscillator, baud rate generator, and digital phase-locked loop. It utilizes a 40-pin DIP package and functions across an industrial temperature range of -40°C to +100°C.

Specialized Feature Summary

• Dual full-duplex communication channels with independent configuration
• Supports multi-protocol formats including async, monosync, bisync, SDLC/HDLC, and HDLC loop
• Integrated FIFO buffers consisting of 4-byte transmit and 8-byte receive depths
• Hardware error detection capabilities using CRC-16 or CRC-CCITT algorithms

Specialized Applications

• High-speed serial networking interfaces
• Industrial control system communication links
• Multi-protocol data terminal equipment

Specialized Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compatibility with existing system power supplies operating between 4.5V and 5.5V before integration into new designs.

Specialized Selection Notes

Select this model when dual-channel synchronous or asynchronous communication is required at speeds up to 5 Mbps. Choose the PEC suffix specifically for through-hole DIP-40 mounting requirements. Consider alternative packages like VSC if surface-mount PLCC-44 is preferred for the same electrical specifications.

Specialized Part Context

This component belongs to the Z85230 enhanced SCC family, which reduces CPU overhead compared to standard controllers. It shares core architecture with variants such as the Z8523016PSC and Z8523016VEC, differing primarily in package style and operational temperature limits defined by their respective suffixes.

Specialized Replacement Considerations

Direct substitutes include Z8523016PSC and Z8523016VEC, which share identical electrical characteristics but differ in packaging and temperature ratings.
