ST16C1550IQ48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1550IQ48TR-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-bit transmit and receive FIFOs for each channel, housed in a 48-pin TQFP surface-mount package measuring 9.2mm x 7mm with a height of 1.2mm. It functions reliably across an industrial temperature range from -40°C to 85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels supporting RS-232 and RS-485 communication standards
• Integrated 16-byte transmit and receive FIFOs per channel to reduce CPU overhead
• Compatible with standard CMOS logic levels and low-voltage operation down to 2.97V

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication
• Embedded control units utilizing RS-485 multi-drop networks
• Data acquisition modules interfacing with legacy serial peripherals

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific manufacturer designation, as component sourcing may list Exar or MaxLinear due to corporate acquisitions. Confirm the presence of the TR suffix indicates tape-and-reel packaging rather than bulk quantities. Ensure the IQ48 designation matches the required thermal and pinout specifications for your PCB layout before finalizing orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual asynchronous serial interfaces are required in a compact form factor. The 4 Mbps speed capability suits high-throughput applications, while the 16-byte FIFOs help manage data bursts efficiently. Verify that the 48-pin TQFP footprint aligns with existing board designs, as single-channel alternatives like the ST16C1550IQ48 exist without the trailing TR suffix.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x family of UART controllers, originally developed by Exar and now produced under MaxLinear. The family provides robust serial I/O solutions for embedded systems. The ST16C1550 variant specifically offers two channels, distinguishing it from single-channel models in the same series.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C1550IQ48 serves as a direct functional equivalent for the ST16C1550IQ48TR-F if reel packaging is not strictly required. Cross-reference with other dual-channel UARTs from the same manufacturer family for potential pin-compatible upgrades.
