SC16C752IB48,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C752IB48,128 is a dual universal asynchronous receiver/transmitter (UART) featuring 64-byte transmit and receive FIFOs. It supports data rates up to 5 Mbits/s at 3.3 V and 5 V, with a maximum of 3 Mbits/s at 2.5 V. The device operates within a voltage range of 2.5 V to 5 V and utilizes a 48-lead LQFP package. It includes automatic hardware and software flow control, programmable baud rate generation, and interrupt capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels with 64-byte FIFOs for each direction
• Supports both hardware (Auto-RTS/CTS) and software (Xon/Xoff) flow control
• Programmable trigger levels for DMA signaling and interrupt generation
• Internal loop-back capability for on-board diagnostics

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed serial communication interfaces in industrial systems
• Multi-port expansion for microcontrollers with limited native UARTs
• Modem control applications requiring CTS, RTS, DSR, and DTR signals

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IB48 corresponds to the LQFP48 plastic low profile quad flat package variant. Confirm that the component meets RoHS compliance requirements for your target assembly process. Ensure the supply chain source provides valid traceability documentation for this NXP USA Inc. product line.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when pin compatibility with the SC16C2550 is required alongside enhanced FIFO depth. Choose the 48-LQFP package if surface mount space allows for larger footprints compared to smaller packages. Verify that the host system can support the 8-bit parallel bus interface architecture utilized by this device.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C752 series of dual UARTs manufactured by NXP Semiconductors. It serves as an enhanced successor to earlier single-channel or lower-capacity UART designs, offering increased buffer sizes to reduce processor overhead during high-throughput serial data transfers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C752 is pin-compatible with the SC16C2550. Designers migrating from legacy UARTs should verify register mapping differences, particularly regarding the Enhanced Feature Register (EFR) and Transmission Control Register (TCR) implementations.
