The ST16C550IJ-F44 is a single-channel UART (Universal Asynchronous Receiver/Transmitter) from Exar Corporation. The 'IJ' likely refers to the package type, possibly indicating a specific type of QFP (Quad Flat Package), and '44' indicates the pin count. The '-F' denotes a lead-free version. This UART is a fundamental component in systems requiring serial communication, providing a versatile solution for converting parallel data to serial and vice versa.

Applications

• Embedded systems requiring serial communication
• Industrial automation equipment
• Computer peripherals and serial ports
• Point-of-Sale (POS) systems
• Networking devices
• Data acquisition systems

Features

• Single UART channel
• Data rates up to 5 Mbps

Additional Details

The ST16C550IJ-F44 operates on a 5V power supply. It supports 5, 6, 7, or 8 data bits with selectable even, odd, or no parity. It also supports 1 or 2 stop bits. The 44-pin package is designed for surface mount PCB assembly. The lead-free composition ensures compliance with environmental regulations.

Its compatibility with standard UART protocols makes it suitable for a variety of serial communication applications. The internal FIFO buffers and flow control features enable efficient and robust data handling, crucial for reliable system performance. The 'IJ' package variant and pin count (44) may indicate specific dimensions or thermal characteristics appropriate for particular board layouts. Its compliance with RoHS standards makes it ideal for modern electronic designs.
