SC16C650BIBS,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C650BIBS,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 within an industrial temperature range of -40 °C to +85 °C. The device features 32-byte transmit and receive FIFOs with error flags, supporting data rates up to 3 Mbit/s at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V. It includes an integrated infrared encoder/decoder compliant with IrDA version 1.0, automatic hardware/software flow control, and DMA signaling via RXRDY and TXRDY pins. The component is housed in an HVQFN32 package.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Confirm that the component meets all required environmental standards and voltage tolerances for the target application before finalizing procurement decisions.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this UART when pin compatibility with industry-standard 16C450/550 devices is required alongside enhanced FIFO capabilities. Ensure the system design accommodates the specific interrupt trigger levels and flow control logic supported by the internal registers.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the SC16C650B family of UARTs designed as upward solutions to standard 16C450 and 16C550 devices. It maintains register compatibility while providing larger memory buffers and additional control features such as programmable Xon/Xoff characters and sleep modes.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C650BIA44 (PLCC44), SC16C650BIB48 (LQFP48), and SC16C650BIN40 (DIP40) are functionally equivalent variants within the same product family, differing only in package style.
