ST16C2550IQ48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C2550IQ48TR-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 4 Mbps. The device features 16-byte transmit and receive FIFOs, enabling efficient data buffering for serial communication applications. It is housed in a 48-pin Thin Quad Flat Package (TQFP) with surface mount installation. The component is rated for an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as MaxLinear, Inc., noting that prior iterations may have been associated with Exar. Ensure the package type matches the 48-pin TQFP requirement for your PCB layout. Check for RoHS compliance status if required by your manufacturing standards.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual asynchronous serial ports are required in a compact surface-mount form factor. The 4 Mbps maximum data rate suits most standard industrial protocols. Verify that the 2.97V minimum supply voltage aligns with your system's power rails. Consider the -40°C to +85°C temperature range against your environmental constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C2550 series of VLIO UARTs. It is functionally similar to the ST16C2550IQ48 but differs in packaging format, with the 'TR' suffix denoting tape and reel delivery. It serves as a high-performance serial interface solution replacing older legacy UART controllers in modern embedded designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C2550IQ48 is a pin-compatible alternative in tube packaging. For single-channel requirements, the ST16C1550 series offers comparable functionality with reduced pin count.
