ST16C550IQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C550IQ48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports data rates up to 1.5 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V, compatible with both 3.3 V and 5 V logic systems. It is housed in a 48-pin Thin Quad Flat Package (TQFP) with dimensions of 7x7 mm. The component is rated for an industrial operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Single UART channel with 16-byte Tx/Rx FIFOs
• Compatible with Intel and Motorola bus protocols
• Supports baud rates up to 1.5 Mb/s
• Operates on 3.3 V or 5 V power supplies

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication gateways
• Embedded system serial interfaces
• Data acquisition systems requiring asynchronous serial connectivity

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix IQ48 to confirm the 48-pin TQFP package and industrial temperature grade. Confirm RoHS compliance status through official documentation as requirements vary by region. Check for end-of-life notices or obsolescence warnings directly from MaxLinear before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single high-speed UART interface with FIFO buffering is required in space-constrained designs. Ensure the application environment stays within the -40°C to +85°C temperature range. Verify that the host system supports the necessary voltage levels for the 2.97V to 5.5V operating range.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C55xD series of UART controllers. It shares functional similarities with other members like the ST16C554 but differs in channel count. The ST16C550 provides a cost-effective solution for applications needing only one asynchronous serial port with enhanced buffering capabilities compared to standard 16550-compatible devices.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-to-pin replacements may include the SC16C550 from NXP or similar variants from Exar. Verify electrical characteristics and register compatibility before substitution.
