TL16C750FNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C750FNR is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by Texas Instruments. It features a 64-byte FIFO for both transmit and receive operations to enhance data throughput and reduce CPU overhead. The device supports data rates up to 1 Mbaud and operates within a supply voltage range of 3 V to 5.25 V. It is housed in a 48-pin TSSOP package and is rated for an operating temperature range of -40°C to +85°C. Key functional blocks include a baud rate generator, modem interface controller, and interrupt logic.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 64-byte transmit and receive FIFOs minimize processor intervention during high-speed serial communication.
• Supports standard asynchronous protocols with programmable data word lengths, parity, and stop bits.
• Includes full hardware modem control signals for automatic flow management without software polling.
• Features a versatile baud rate generator capable of generating standard clock rates from the system clock.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication links.
• Embedded controllers managing multiple peripheral devices via UART interfaces.
• Telecommunications equipment utilizing standard asynchronous data transmission.
• Point-of-sale terminals and barcode scanners needing robust serial I/O capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'FNR' against the manufacturer's current datasheet to confirm package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 48-pin TSSOP configuration. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with substantial buffering is required. Compare against the TL16C550 series if lower cost is prioritized over FIFO depth. Consider the TL16C754BPNR if multiple UART channels are needed in a single package. Verify that the 1 Mbaud maximum speed meets the application's timing requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C75x family of UARTs, which are CMOS versions of the industry-standard 16C550. The family provides backward compatibility while offering improved performance through larger FIFOs and lower power consumption. It is widely used in legacy system upgrades and new designs requiring standard RS-232 or RS-485 interfacing.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C750PM is a pin-compatible alternative in a different package. The TL16C550N is a legacy equivalent but lacks the 64-byte FIFOs. Verify that any substitute maintains the same voltage levels and interrupt logic compatibility.
