Z8523316VSC

Specialized Overview

The Z8523316VSC is a single-channel Enhanced Mono Serial Communication Controller (EMSCC) from Zilog, operating at a maximum clock frequency of 16 MHz with a data rate up to 0.625 MBps. It utilizes CMOS technology and is housed in a 44-pin PLCC plastic package. The device supports a supply voltage range of 4.5V to 5.5V and operates within a commercial temperature range of 0°C to 70°C.

Specialized Feature Summary

• Includes a 4-byte transmit FIFO and an 8-byte receive FIFO to reduce CPU overhead.
• Features automatic SDLC packet handling capabilities including flag transmission and frame reset.
• Supports software generation of the interrupt acknowledge signal (/INTACK).
• Provides faster response times for /INT and /DTR//REQ pins compared to standard SCC.

Specialized Applications

• Full-duplex data communications controller applications.
• SDLC protocol implementation requiring automated packet handling.
• Microprocessor systems requiring reduced interface logic complexity.

Specialized Procurement Notes

Verify the specific suffix 'VSC' corresponds to the 16 MHz speed grade and PLCC package variant. Confirm that the component meets the required commercial temperature specifications for the intended application environment before finalizing procurement orders.

Specialized Selection Notes

Select this component when a single-channel serial interface is sufficient, as opposed to the dual-channel Z85230 ESCC. Ensure the system design accommodates the 44-pin PLCC footprint and requires the enhanced FIFO depths for optimal performance.

Specialized Part Context

This part belongs to the Zilog SCC family introduced in 1981. It serves as the single-channel EMSCC version of the Z85230 ESCC, offering backward compatibility with existing SCC designs while providing improved data handling and reduced CPU overhead through hardware enhancements.

Specialized Replacement Considerations

The Z85230 ESCC is a dual-channel alternative within the same family. Verify if the additional channel is necessary or if the single-channel configuration of the Z85233 is adequate for the system requirements.
