SC16C752BIBS,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C752BIBS,151 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 operation, 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 an HVQFN32 package (SOT617-1), measuring 5 mm x 5 mm x 0.85 mm. It includes automatic hardware/software flow control, programmable baud rate generation, and modem interface control functions.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this part when a dual UART solution with large FIFOs is required for high-speed data transfer. Ensure the host system supports the necessary parallel bus interface timing. Consider the HVQFN32 package constraints for PCB layout. Verify voltage compatibility if operating at 2.5 V, as maximum baud rate reduces to 3 Mbit/s.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C752B belongs to the SC16C752 family of dual UARTs. It serves as an enhanced version of earlier designs like the SC16C2550, offering improved flow control and diagnostic features. The IB variant specifically denotes the HVQFN32 package option, distinguishing it from the LQFP48 package version (SC16C752BIB48).

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C752B is pin-compatible with the SC16C2550. It is also software and pin compatible with the TL16C752. Designers migrating from these parts should verify Enhanced Feature Register (EFR) configurations.
