Z8523010PEC

Specialized Overview

The Z8523010PEC is a dual full-duplex Serial Communication Controller (SCC) from the Z85230 family, designed to reduce external logic requirements. It supports processing speeds up to 5 Mbps and accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. The device handles multi-protocol formats including async, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop modes. Data encoding supports NRZI, FM0, FM1, and Manchester modes with CRC-16 or CRC-CCITT error detection. It features a 4-byte transmit FIFO and an 8-byte receive FIFO. The component operates within a temperature range of -40°C to +100°C and utilizes a 40-pin DIP package.

Specialized Feature Summary

• Dual full-duplex channels with integrated baud rate generation and clock control
• Support for multiple synchronous and asynchronous communication protocols
• Hardware-assisted data encoding and CRC error detection capabilities
• Integrated FIFO buffers to minimize CPU overhead

Specialized Applications

• Serial communication interfaces in embedded systems
• Network controller implementations requiring protocol flexibility
• Industrial equipment utilizing RS-232 or RS-422/485 links
• Data acquisition systems needing reliable serial data transfer

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pin compatibility and environmental ratings. Confirm availability status as older SCC families may have limited stock or end-of-life implications. Ensure the DIP-40 package fits the target PCB footprint before procurement.

Specialized Selection Notes

Select this part when dual-channel serial communication is required with high protocol support. Compare against the Z85C30 series if lower speed is acceptable or the Z16C30 series if higher throughput is needed. Verify that the 5 Mbps maximum speed meets system requirements and that the operating temperature range suits the deployment environment.

Specialized Part Context

This component belongs to the Zilog Z85230 enhanced SCC family, which improves upon earlier designs by reducing CPU overhead through advanced packet handling and cycle access recovery. It serves as a bridge between parallel bus architectures and serial peripheral devices, offering a robust solution for legacy and industrial networking applications.

Specialized Replacement Considerations

Direct substitutes include other variants within the Z85230 family such as the Z8523008PEC or Z8523016PEC, depending on frequency and FIFO requirements. Cross-family replacements like the Z85C3010PEC offer similar functionality but with different performance characteristics.
