ST16C1550CQ48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1550CQ48TR-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 4 Mbps. The device features 16-byte transmit and receive FIFOs to enhance throughput efficiency. It is housed in a 48-pin TQFP surface-mount package with dimensions of 7x7 mm and a height of 1.2 mm. The component supports RS-232, RS-422, and RS-485 standards and functions reliably across an operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 16-byte transmit and receive FIFO buffers for improved data handling
• Supports multiple communication protocols including RS-232, RS-422, and RS-485
• Wide operating voltage range compatible with 3.3V and 5V logic systems

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems requiring robust serial communication
• Embedded devices utilizing RS-485 multi-drop networks
• Telecommunications equipment interfacing via RS-232 or RS-422

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation on official documentation, as historical records indicate prior production by Exar before acquisition by MaxLinear. Confirm that the specific ordering suffix corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with the intended voltage levels and protocol requirements for the target application design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is sufficient for the system architecture. Compare against the ST16C2550IQ48-F if dual-channel capability is required instead of a single channel. Consider the physical footprint constraints of the 48-TQFP package relative to available PCB space and thermal dissipation requirements for the specific enclosure design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x series of UART interface controllers designed for high-performance serial communication. It serves as a bridge between parallel processor buses and asynchronous serial data streams. The integration of FIFOs distinguishes it from legacy 16550-compatible devices that lack buffering capabilities, reducing CPU overhead during high-speed data transfers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C1550CQ48-F is a non-reel variant of the same functional device. Verify pinout compatibility if substituting with other single-channel UARTs from the ST16C155x family.
