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 supports the 8-bit parallel bus interface and provides adequate clocking for the baud rate generator. Consider the HVQFN32 package constraints for PCB layout and thermal management during design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C752B series, which includes variants like the SC16C752BIB48 in an LQFP48 package. The IB suffix denotes the HVQFN32 plastic thermal enhanced very thin quad flat package. The series is designed to be pin and software compatible with legacy components like the SC16C752 and TL16C752.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C752B is pin-compatible with the SC16C2550. It is also software and pin compatible with the SC16C752 and TL16C752. Verify that any replacement maintains compatibility with the specific bus interface requirements and voltage levels of the target application.
