Z16C3010VEC00TR

Overview

The Z16C3010VEC00TR is a CMOS Universal Serial Controller (USC) manufactured by Zilog. It features two independent full-duplex channels supporting data rates up to 10 Mbps. Each channel includes dual baud rate generators, a digital phase-locked loop for clock recovery, and 32-byte FIFOs for both receiver and transmitter operations. The device supports multi-protocol communication including asynchronous, synchronous byte-oriented, and bit-oriented formats. It utilizes a flexible bus interface compatible with 8-bit or 16-bit systems, directly supporting 680X0 and 8086 families. Electrical specifications include a supply voltage range of 4.5V to 5.5V and a typical operating current of 7mA.

Feature Summary

• Dual-channel architecture with independent interrupt structures and DMA interfaces for high-speed data transfer
• Multi-protocol support enabling configuration for asynchronous, HDLC/SDLC, Bisync, and transparent modes
• Integrated digital phase-locked loop and dual baud rate generators per channel for precise clock recovery
• Flexible CPU bus interface allowing direct connection to microprocessors via multiplexed or non-multiplexed modes

Applications

• High-speed serial data communications in industrial control systems
• Multiprotocol data terminal equipment interfacing
• Embedded systems requiring dedicated UART functionality with DMA support

Procurement Notes

Verify component authenticity through authorized distributors as the part may be subject to obsolescence notices. Confirm package type and temperature grade match design requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this controller when dual-channel serial communication with independent protocol handling is required. Verify that the target system bus supports the necessary timing parameters for 110 ns cycle times. Consider the available package options based on board space constraints. Evaluate whether the integrated FIFOs and DMA capabilities meet throughput requirements without excessive CPU intervention.

Part Context

This component belongs to the Z16C30 family of Universal Serial Controllers. It serves as a peripheral interface for microprocessors, converting between parallel processor data and serial transmission streams. The device integrates complex serial logic functions previously requiring multiple discrete chips, simplifying system design for applications demanding robust serial connectivity.

Replacement Considerations

Consult official documentation for cross-reference information. Verify pin compatibility and electrical characteristics before substituting with other USC models. Ensure that any alternative device supports the same multi-protocol configurations and bus interface requirements.
