NS16C2752TVA/NOPB

Overview

The NS16C2752TVA/NOPB is a dual universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU intervention. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports standard serial communication protocols. It is housed in a 48-pin TQFP package suitable for surface-mount applications. The component functions across an industrial temperature range from -40°C to +85°C, ensuring reliable operation in demanding environments.

Feature Summary

• Dual independent UART channels with dedicated 16-byte FIFO buffers for efficient data handling
• Supports standard asynchronous serial communication protocols compatible with RS-232 and RS-485 interfaces
• Integrated modem control signals and interrupt capabilities for streamlined system integration

Applications

• Industrial automation systems requiring robust serial communication
• Embedded control units with multiple peripheral connections
• Telecommunications equipment utilizing standard UART interfaces

Procurement Notes

Verify the specific suffix 'V' indicates the tape and reel packaging configuration when ordering. Confirm the 'A' grade denotes the extended industrial temperature rating. Ensure compatibility with the target PCB footprint for the 48-pin TQFP package. Check for RoHS compliance documentation as indicated by the NOPB suffix. Validate that the required quantity aligns with the manufacturer's standard packaging multiples.

Selection Notes

Select this component when dual-channel UART functionality with FIFO buffering is required. Compare against single-channel alternatives if only one port is needed to optimize cost and board space. Consider the operating voltage range to ensure compatibility with the system power supply. Evaluate the pin count and package size against available PCB real estate constraints.

Part Context

This part belongs to the NS16C2752 series of dual UART controllers. It serves as a successor or variant to earlier single-channel UART designs, offering increased integration. The device is designed to replace legacy discrete UART solutions in modern embedded systems. It shares functional similarities with other members of the NS16C family but provides enhanced throughput via its FIFO architecture.

Replacement Considerations

Direct replacements may include the NS16C2752TV or NS16C2752TVA variants depending on packaging requirements. Cross-reference with NS16C2552-based designs if single-channel operation suffices. Verify pin-to-pin compatibility before substituting with other dual UART ICs from different manufacturers.
