Z8023016VSC00TR

Specialized Overview

The Z8023016VSC00TR is a dual full-duplex enhanced serial communication controller (ESCC) from the ZiLOG SCC family. It operates within a supply voltage range of 4.5V to 5.5V and supports processing speeds up to 5 Mbps. The device features a 4-byte transmit FIFO and an 8-byte receive FIFO for efficient data handling. It accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. The component is housed in a 44-pin PLCC package with J-leads and is designed for surface mount installation.

Specialized Feature Summary

• Dual full-duplex channels supporting multi-protocol formats including async, monosync, bisync, and SDLC/HDLC
• Integrated hardware encoding capabilities for NRZI, FM0, FM1, and Manchester modes
• On-chip CRC-16 or CRC-CCITT error detection mechanisms
• Enhanced packet handling response and improved cycle access recovery time

Specialized Applications

• Networking applications requiring fully integrated serial communication solutions
• Systems utilizing multi-protocol format transmission standards
• Hardware designs aiming to reduce external logic requirements through high integration

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as older manufacturing runs may differ. Check current product lifecycle status since this model may be discontinued. Ensure the supplier provides valid traceability for vintage semiconductor components.

Specialized Selection Notes

Select this component when dual full-duplex ESCC functionality is required with speeds up to 5 Mbps. Compare against the Z85230 series if industrial temperature ranges are necessary. Verify that the 44-pin PLCC footprint matches the target PCB layout constraints. Consider the FIFO depths relative to system DMA capabilities.

Specialized Part Context

This part belongs to the Z80230 Enhanced Serial Communication Controller family. It shares core architecture with the Z85230 but typically differs in operating temperature specifications. The '16' indicates support for 16 MHz clock speeds. The 'VSC' designation identifies the 44-pin PLCC plastic leaded chip carrier package variant.
