SC16C751BIBS,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C751BIBS,151 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 supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. It features 64-byte transmit and receive FIFOs with error flags, automatic hardware flow control via RTS/CTS, and a programmable baud rate generator accepting clocks up to 80 MHz. Packaged in an HVQFN24 plastic thermal enhanced very thin quad flat package (SOT616-3), it includes sleep mode for low power consumption.

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 up to 80 MHz input clock
• Sleep mode and low power operation capabilities

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 component matches the specific ordering code SC16C751BIBS,151 to ensure correct packaging and voltage variants. Confirm that the supplier provides original manufacturer documentation to validate authenticity. Check for RoHS compliance status as indicated in official product specifications before finalizing acquisition.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large FIFO buffers is required to minimize processor interrupts. Ensure the system design accommodates the HVQFN24 package dimensions and thermal requirements. Verify compatibility with existing 16C450 software if migrating from legacy designs, noting the special initialization sequence needed for receiver clock activation.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C751B series of UARTs designed as upward solutions to standard 16C450 devices. It replaces older UARTs by providing significantly larger FIFO memory and advanced flow control features while maintaining register compatibility. The IB suffix indicates the specific tape and reel packaging variant within the broader SC16C751B family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C751B is functionally equivalent to the SC16C750B but offers single-channel configuration instead of dual-channel. When replacing legacy 16C450 components, ensure the special software initialization sequence is implemented to enable the receiver clock.
