Z8523310FSC00TR

Specialized Overview

The Z8523310FSC00TR is a single-channel Enhanced Mono Serial Communication Controller (EMSCC) manufactured by Zilog. It operates at a maximum clock frequency of 16 MHz and supports data rates up to 4 MHz. The device features a 4-byte transmit FIFO and an 8-byte receive FIFO to reduce CPU overhead. It utilizes a 44-pin PQFP package, functions on a +5V supply voltage, and supports standard CMOS logic levels.

Specialized Feature Summary

• Integrates hardware support for SDLC packet handling, including automatic flag transmission and frame reset capabilities.
• Includes dedicated FIFO buffers to minimize processor intervention during data transfer operations.
• Simplifies CPU interface design through relaxed databus setup time requirements and software-generated interrupt acknowledge signals.

Specialized Applications

• Full-duplex serial data communications systems
• SDLC protocol implementation in embedded controllers
• High-speed asynchronous/synchronous communication interfaces

Specialized Procurement Notes

Verify the specific suffix '10' against the manufacturer's official datasheet to confirm the operating temperature range and speed grade. Ensure the procurement channel provides traceable documentation matching the Z85233 EMSCC specifications. Confirm that the 44-pin PQFP package matches the target PCB footprint requirements before finalizing orders.

Specialized Selection Notes

Select this component when a single-channel serial controller with integrated FIFOs is required to lower system bus traffic. Compare against the dual-channel Z85230 ESCC if only one communication port is needed. Evaluate the 16 MHz performance limit against the system clock availability to ensure timing compatibility with the host microprocessor.

Specialized Part Context

This part belongs to the Zilog SCC family, specifically the Enhanced Mono Serial Communication Controller (EMSCC) line. It serves as a single-channel variant of the Z85230 ESCC, designed to maintain software compatibility while offering improved data handling through deeper FIFOs and simplified interface logic.

Specialized Replacement Considerations

The Z85230 ESCC is a compatible dual-channel alternative within the same family. Verify pinout compatibility and check if the additional channel functionality is required or can be left unconnected in the replacement scenario.
