SC16C752BIB48,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C752BIB48,128 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 supply voltages, 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 measures 7 × 7 × 1.4 mm. It includes automatic hardware and software flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART solution with high-speed performance and extensive flow control options is required. Ensure the host system can accommodate the LQFP48 package dimensions and provides the necessary voltage levels for the 5 V tolerant inputs. Consider the pin compatibility with legacy designs if migrating from older UART families.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C752B series, which are designed as drop-in replacements for earlier UART generations like the SC16C752 and TL16C752. The IB48 suffix specifically denotes the LQFP48 package variant, distinguishing it from the HVQFN32 option. It serves as a bridge between parallel bus architectures and serial communication protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The datasheet confirms pin and software compatibility with the SC16C752 and TL16C752. It is also pin-compatible with the SC16C2550. Verify that any substitute maintains the same LQFP48 footprint and electrical characteristics for direct replacement.
