Z8523316VSC00TR

Specialized Overview

The Z8523316VSC00TR is a single-channel Enhanced Mono Serial Communication Controller (EMSCC) from the Zilog SCC family. It operates on CMOS technology with a supply voltage range of +4.50 V to +5.50 V and supports clock frequencies up to 16 MHz. The device features a 7000-gate count, a 4-byte transmit FIFO, and an 8-byte receive FIFO. It utilizes a 44-pin PLCC package for surface-mount installation.

Specialized Feature Summary

• Single-channel full-duplex data communications controller supporting popular protocols
• Integrated 4-byte transmit and 8-byte receive FIFOs to reduce CPU overhead
• Automatic packet handling improvements in SDLC mode including flag transmission and frame reset
• Simplified CPU hardware interface with software-generated interrupt acknowledge signal

Specialized Applications

• Full-duplex data communications systems
• SDLC protocol implementations requiring automatic packet handling
• Microprocessor families requiring simplified serial interface logic

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Ensure the single-channel configuration matches system requirements before procurement.

Specialized Selection Notes

Select this component when a single-channel serial interface is sufficient compared to the dual-channel Z85230 ESCC. Verify that the 16 MHz maximum operating frequency meets system timing requirements. Check that the 44-PLCC package footprint aligns with the PCB layout design.

Specialized Part Context

This part belongs to the Z8523x series of serial communication controllers. It serves as the single-channel variant of the Z85230 ESCC, offering similar functionality with reduced pin count and cost for applications requiring only one serial port.

Specialized Replacement Considerations

Z8523016VSC00TR: Dual-channel version with identical electrical characteristics but additional channel resources.
