Z8523316FSC00TR

Specialized Overview

The Z8523316FSC00TR 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 legacy designs. The device features a 4-byte transmit FIFO and an 8-byte receive FIFO to reduce CPU overhead. It supports clock frequencies up to 16 MHz, operates on a single +5V supply, and utilizes a 44-pin PQFP package.

Specialized Feature Summary

• Integrated FIFO buffers for improved packet handling
• Automatic SDLC frame management capabilities
• Simplified CPU hardware interface design

Specialized Applications

• Full-duplex serial data communication systems
• SDLC protocol implementation
• Microprocessor peripheral interfacing

Specialized Procurement Notes

Verify the specific suffix '16FSC00TR' against official manufacturer documentation to confirm operational speed, temperature range, and packaging details. Ensure the component matches the required 44-pin PQFP form factor and that the ordering information aligns with the intended system environment.

Specialized Selection Notes

Select this component when a software-compatible upgrade to the standard SCC is required. The EMSCC architecture provides deeper data buffers and simplified interrupt handling compared to previous generations. Verify that the target microprocessor bus timing meets the specified setup and hold requirements for reliable operation.

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. The device maintains backward compatibility with existing SCC designs while offering enhanced performance through reduced CPU intervention and improved signal integrity.

Specialized Replacement Considerations

The Z85233 is functionally compatible with the Z85230 ESCC and standard Z8523 SCC. When replacing legacy components, verify that the system logic accommodates the updated timing parameters and FIFO depth differences inherent to the EMSCC architecture.
