TL16C550DIPFBR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DIPFBR is a single-channel Asynchronous Communications Element (ACE) manufactured by Texas Instruments. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 1.5 Mbaud with a 24-MHz clock at 5 V. The device features 16-byte transmit and receive FIFOs, each storing three additional error status bits for the receiver. It includes programmable baud rate generation, independent interrupts, and autoflow control capabilities. The component is housed in a 48-pin Low-Profile Quad Flat Package (LQFP) and is designed for industrial temperature ranges.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Autoflow Control: Programmable Auto-RTS and Auto-CTS modes automatically manage serial data flow using RTS output and CTS input signals to reduce software overhead.
• Interrupt System: Fully prioritized interrupt system allows tailoring to minimize software management of the communications link.
• Modem Control: Complete modem control capability including DTR, RTS, DSR, CTS, RI, and DCD signals.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial conversions between CPUs and peripheral devices or modems.
• Embedded systems requiring asynchronous communication interfaces with reduced CPU intervention.
• Industrial applications utilizing the extended operating temperature range.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure compatibility with the target system's voltage levels and interface requirements before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model for applications requiring high-speed asynchronous communication with hardware flow control. Consider the 48-pin LQFP package constraints and verify that the host system can support the required address strobe and chip select logic.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550D is an upgrade of the TL16C550C, offering higher speed capabilities while maintaining functional equivalence to the TL16C450 on power-up. It serves as a robust solution for legacy UART software compatibility while providing enhanced performance through larger FIFOs and autoflow control.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DI is functionally equivalent but may differ in environmental ratings. Verify pinout compatibility if substituting with other variants in the TL16C550 family.
