ST16C1551CQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1551CQ48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by MaxLinear. It integrates a 64-byte transmit FIFO and a 64-byte receive FIFO to enhance data throughput and reduce CPU overhead. The device supports data rates up to 4 Mbps and operates within a supply voltage range of 2.97V to 5.5V. It is housed in a 48-pin Thin Quad Flat Package (TQFP) with dimensions of 7mm x 7mm and a height of 1.2mm. The component functions reliably across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates deep 64-byte transmit and receive FIFOs for efficient data buffering
• Supports high-speed asynchronous serial communication up to 4 Mbps
• Compatible with standard UART protocols including RS-232, RS-422, and RS-485

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring robust serial communication
• Embedded control units with multiple peripheral interfaces
• Telecommunications equipment utilizing asynchronous data transfer

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's current datasheet to confirm package type and environmental rating. Ensure compatibility with existing PCB footprints for the 48-TQFP configuration. Cross-reference the part number with official MaxLinear distribution channels to validate authenticity and current production status before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with substantial buffering is required. The 64-byte FIFO depth distinguishes it from standard 16-byte variants. Verify that the 48-pin TQFP package fits the design constraints. Confirm that the 4 Mbps speed requirement aligns with system timing specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x series of UART controllers. It serves as a bridge between parallel microprocessor buses and serial communication lines. The device replaces older 16550-compatible UARTs by offering increased FIFO capacity and broader voltage support while maintaining pin compatibility with legacy designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C1550IQ48-F is a similar single-channel variant but typically features 16-byte FIFOs rather than 64 bytes. Direct substitution requires verifying if the reduced buffer size meets application latency requirements.
