TL16C550DIPTR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DIPTR is a single-channel Asynchronous Communications Element (ACE) manufactured by Texas Instruments, housed in a 48-pin LQFP package. It supports data rates up to 1.5 Mbaud with a 24-MHz clock at VCC = 5V, and up to 1 Mbaud at VCC = 3.3V. The device features 16-byte transmit and receive FIFOs, operates on a supply voltage of 2.25V to 5.5V, and draws 10 mA. It functions within a temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Autoflow control capability with programmable Auto-RTS and Auto-CTS for automatic serial data flow management
• Programmable baud rate generator supporting divisors from 1 to 65535
• Fully prioritized interrupt system with independent control of transmit, receive, line status, and data set interrupts

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial data conversion in communication systems
• Modem control applications requiring direct RJ11 cable drive capabilities
• Systems utilizing DMA controllers via TXRDY and RXRDY signaling

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a functional upgrade to the TL16C550C is required with higher speed capabilities. It serves as a drop-in replacement for TL16C450 software but offers enhanced performance. Consider the 48-pin LQFP package constraints and verify that the host system supports the required 3-state TTL drive capabilities for the bidirectional data bus.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550D is a speed and operating voltage upgrade of the TL16C550C asynchronous communications element. It maintains functional equivalence to the TL16C450 upon power-up while offering improved baud rate generation and lower voltage operation options compared to its predecessors in the family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DI is functionally equivalent to the TL16C550D. Verify pin compatibility if substituting with other packages such as the 32-pin RHB or 24-pin ZQS, as signal availability varies by package type.
