Z16C3220VSC1660TR

Overview

The Z16C3220VSC1660TR is a multiprotocol data communications device featuring an on-chip dual-channel DMA controller. It integrates a high-speed serial communications channel with performance capabilities up to 20 Mbit/sec full-duplex operation. The device supports asynchronous, HDLC/SDLC, and synchronous byte-oriented protocols. It includes two baud rate generators, a digital phase-locked loop for clock recovery, and 32-byte FIFOs for both receiver and transmitter. The unit operates within a voltage range of 4.5V to 5.5V and draws 7mA of supply current. It is housed in a 68-pin PLCC package and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Dual-channel DMA with support for single buffer, pipelined, array-chained, and linked-array chained modes.
• Multiprotocol serial communication supporting asynchronous, HDLC/SDLC, and BISYNC formats.
• Flexible bus interface compatible with 8-bit or 16-bit microprocessor buses including 680X0 and 8086 families.
• Integrated time slot assigners for ISDN, T1, and E1 applications.

Applications

• ISDN, T1, and E1 (CEPT) telecommunications systems
• High-throughput serial data communications interfaces
• Microprocessor peripheral controllers requiring direct memory access

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix indicates the correct package and temperature grade. Check for RoHS compliance status as indicated in official documentation. Ensure storage conditions respect moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component when system design requires integrated serial protocol handling combined with high-speed DMA transfers. Verify that the host processor bus interface matches the configurable 8-bit or 16-bit width options. Ensure the operating environment stays within the specified commercial temperature range. Confirm power supply stability within the 4.5V to 5.5V window for reliable operation.

Part Context

This part belongs to the Zilog Z16C32 IUSC series, which stands for Integrated Universal Serial Controller. The series is designed to reduce board space and chip count by combining serial control and DMA functions. The Z16C3220 variant specifically denotes the speed grade and configuration within the broader family of multiprotocol controllers.
