Z8523008PSG

Specialized Overview

The Z8523008PSG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It operates at a frequency of 8 MHz with a supply voltage range of 4.5 V to 5.5 V and a typical operating current of 4 mA. The device supports serial interfaces and is housed in a PLCC-44 package for surface mount installation. It functions within a temperature range of 0°C to +70°C.

Specialized Feature Summary

• Supports asynchronous, synchronous byte, synchronous HDLC, SDLC, X.25, BISYNC, and extended synchronization protocols.
• Includes a 4-byte transmit FIFO buffer and an 8-byte receive FIFO buffer.
• Features vectored interrupt capabilities with daisy-chain support via IEI/IEO pins.

Specialized Applications

• Network controller systems requiring serial data communication.
• Microprocessor peripheral interfaces for data transfer.
• Modem control applications utilizing hardware flow control signals.

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Confirm that the component meets all required environmental standards for the intended deployment environment before integration into final designs.

Specialized Selection Notes

Select this component when a dedicated serial communications controller with integrated FIFO buffers is required. Ensure the host system supports the necessary bus timing and interrupt handling mechanisms compatible with the ESCC architecture.

Specialized Part Context

This part belongs to the Z85230 series of Enhanced Serial Communications Controllers. It serves as a specialized interface between microprocessors and serial communication lines, offering enhanced features over standard SCC devices such as improved interrupt handling and FIFO buffering.

Specialized Replacement Considerations

Consult the manufacturer's product specification document for officially confirmed substitute part numbers. Verify functional equivalence regarding protocol support and electrical specifications before substitution.
