SC16C751BIBS,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C751BIBM,157 is a single-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates at supply voltages of 2.5 V, 3.3 V, or 5 V with an industrial temperature range of -40 °C to +85 °C. The device features 64-byte transmit and receive FIFOs, supporting data rates up to 5 Mbit/s at 5 V/3.3 V and 3 Mbit/s at 2.5 V. It utilizes an HVQFN24 package (SOT616-3) for surface mount installation.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Single channel UART with 64-byte transmit and receive FIFOs
• Automatic hardware flow control using RTS and CTS signals
• Programmable baud rate generator supporting internal or external clock sources
• Internal loopback capability for on-board diagnostics

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed modem interfaces requiring fast data processing
• Shared network environments needing reduced CPU bandwidth
• Industrial serial communication systems operating in wide temperature ranges

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IBM,157 corresponds to the HVQFN24 package variant. Confirm RoHS compliance status through official documentation. Ensure the special software initialization sequence required for receiver operation is implemented during system integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large FIFO buffers is required. It serves as an upgrade over standard 16C450 designs by providing 64-byte memory instead of none. Ensure the application supports the necessary voltage levels and requires automatic hardware flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C751B is functionally equivalent to the SC16C750B but requires a specific software initialization sequence. It belongs to the SC16C75x series of UART interface ICs designed for high-performance serial communications with enhanced FIFO capabilities compared to legacy devices.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

SC16C750B is a functional equivalent within the same family. Verify software compatibility regarding the required initialization sequence before substitution.
