SC16C752BIB48,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C752BIB48,151 is a dual Universal Asynchronous Receiver/Transmitter (UART) manufactured by NXP Semiconductors. It features two independent UART channels with 64-byte transmit and receive FIFOs. The device supports data rates up to 5 Mbit/s at 3.3 V and 5 V operation, and up to 3 Mbit/s at 2.5 V. It operates within an industrial temperature range of -40 °C to +85 °C. The component is housed in a plastic LQFP48 package with 48 leads and dimensions of 7 × 7 × 1.4 mm.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Pin compatible with SC16C2550 while offering enhanced features via the Enhanced Feature Register.
• Supports software and hardware flow control including programmable Xon/Xoff characters and auto-RTS/CTS.
• Includes internal loopback capability for on-board diagnostics and fully prioritized interrupt system controls.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation and control systems requiring reliable serial communication.
• Embedded systems utilizing microcontrollers that need additional UART ports via parallel bus interface.
• Modem interface applications requiring hardware flow control and modem status monitoring.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IB48 corresponds to the LQFP48 package variant when sourcing components. Confirm that the supply voltage requirements align with the target application's 2.5 V, 3.3 V, or 5 V rails. Ensure the input pins are rated for 5 V tolerance if interfacing with 5 V logic systems.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when pin compatibility with legacy SC16C2550 designs is required alongside modern FIFO enhancements. Consider the LQFP48 package for surface mount assembly needs where board space allows for its 7x7mm footprint. Evaluate the baud rate generator flexibility against the available crystal or external clock frequencies in the design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C752B series of dual UARTs from NXP Semiconductors. It serves as an evolution of earlier UART designs, providing increased throughput through larger FIFO buffers and improved flow control mechanisms. The series is designed to bridge parallel processor buses to serial communication lines efficiently.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C752B is pin and software compatible with the SC16C752 and TL16C752. Designers migrating from these parts can utilize the SC16C752BIB48 directly without schematic changes, benefiting from the added FIFO and flow control enhancements.
