Z8523316FSG

Specialized Overview

The Z8523316FSG is an Enhanced Mono Serial Communication Controller (EMSCC) from the Zilog SCC family. It operates as a full-duplex data communications controller supporting popular protocols with software compatibility to existing designs. The device features a single channel configuration based on Superintegration Technology, incorporating a 4-byte transmit FIFO and an 8-byte receive FIFO to reduce CPU overhead. It supports clock speeds up to 16 MHz and utilizes a 44-pin PQFP package.

Specialized Feature Summary

• Integrated FIFO buffers for improved packet handling and reduced CPU intervention
• Automatic SDLC frame management including flag transmission and error handling
• Simplified CPU hardware interface with relaxed setup time requirements
• Software generation of interrupt acknowledge signals

Specialized Applications

• Full-duplex serial data communication systems
• SDLC protocol implementation
• Microprocessor-based embedded controllers
• High-speed asynchronous/synchronous I/O interfaces

Specialized Procurement Notes

Verify the specific suffix 'FSG' against official documentation to confirm package type and temperature range. Ensure the source document matches the requested part number exactly. Confirm RoHS compliance status if required by the application environment. Check for obsolescence or lifecycle status before finalizing procurement plans.

Specialized Selection Notes

Select this component when a single-channel serial controller with integrated FIFOs is required. It serves as a direct replacement for standard SCC designs needing reduced logic complexity. Consider the 16 MHz maximum operating speed and PQFP packaging constraints during system architecture planning.

Specialized Part Context

This device belongs to the Z85230 ESCC family but offers a mono-channel variant. It maintains backward compatibility with Zilog's original SCC architecture while providing enhanced performance through deeper data buffers and simplified control logic for modern microprocessor integration.

Specialized Replacement Considerations

The Z85233 EMSCC is functionally related to the Z85230 ESCC. Verify pinout compatibility if substituting between mono and dual-channel variants within the same family.
