ST16C2550CQ48 Description

Short technical summary and product information.

The Exar ST16C2550CQ48 is a dual Universal Asynchronous Receiver Transmitter (DUART) integrated circuit designed for reliable serial communication. Each of its two channels is equipped with a 16-byte FIFO buffer, enhancing data flow efficiency and reducing CPU overhead.

 

This IC supports high-speed data transmission up to 4 Mbps per channel and is compatible with RS232 and RS485 protocols. It operates within a voltage range of 2.97V to 5.5V and includes features such as an internal oscillator, timer/counter, modem control, and false start bit detection for robust performance.

 

The ST16C2550CQ48 is housed in a compact 48-pin TQFP (7x7 mm) package, making it suitable for surface mount applications where space is a consideration. Its design is well-suited for industrial automation, networking equipment, point-of-sale devices, and embedded control systems requiring dependable dual asynchronous serial communication.

 

This component is actively supplied and comes in Tape & Reel packaging, facilitating automated assembly processes.
