The ST16C550CJ44TR-F from MaxLinear (previously Exar Corporation) is a universal asynchronous receiver and transmitter, or UART, designed for serial communication applications that require reliable data handling, flexible baud rate programming, and efficient processor interfacing.

If you’re working on embedded systems, industrial controls, communication equipment, modem interfaces, or legacy hardware platforms that rely on 16C550-compatible UART functionality, this part is a dependable choice.

The ST16C550CJ44TR-F is part of MaxLinear's ST16C550 UART family, an improved version of the industry-standard NS16C550, offering higher operating speed and lower access time.

Here's a closer look at the part:

**Key Features of the ST16C550CJ44TR-F**

**![](https://www.componentsense.com/hs-fs/hubfs/undefined-Jun-16-2026-01-05-58-2481-PM.png?width=377&height=368&name=undefined-Jun-16-2026-01-05-58-2481-PM.png)**

**16-Byte Transmit and Receive FIFO**

The ST16C550CJ44TR-F includes 16-byte transmit and receive FIFOs, helping reduce the workload on the external processor. This is especially useful in systems where fast data handling, smoother serial communication, and reduced CPU intervention are important.

**Industry-Standard 16C550 Compatibility**

This UART is pin-to-pin and functionally compatible with the industry-standard 16C550, making it suitable for designs that need a reliable replacement or continued support for existing 16C550-based architecture.

**Wide Operating Voltage Range**

The ST16C550CJ44TR-F operates from 2.97V to 5.5V, allowing it to support both 3.3V and 5V system designs. This gives engineers flexibility when integrating the part into mixed-voltage or legacy platforms.

**Programmable Baud Rate Generator**

The device includes a programmable baud rate generator that can select transmit and receive clock rates from 50 bps up to 1.5 Mbps. This makes it suitable for a wide range of serial communication requirements, from slower control interfaces to higher-speed data transfer applications.

**Full Duplex Serial Communication**

With full duplex operation, the ST16C550CJ44TR-F can transmit and receive data simultaneously. This is essential for communication systems where two-way data exchange needs to happen efficiently and without unnecessary delay.

**Complete Modem Control Capability**

The device includes a standard modem interface with control signals such as CTS, RTS, DSR, DTR, RI, and CD. This makes it suitable for modem-connected systems and other serial communication interfaces that require hardware flow control or status monitoring.

**Internal Loop-Back Mode for Diagnostics**

The ST16C550CJ44TR-F includes an internal loop-back capability for onboard diagnostic testing. This allows transmitted data to be internally routed back to the receiver, helping verify UART operation during testing, troubleshooting, or system validation.

**Low Operating Current**

The ST16C550CJ44TR-F is fabricated using an advanced CMOS process and offers low operating current, with the datasheet listing a typical operating current of 1.2mA. This supports efficient operation in designs where power consumption must be carefully managed.

## **Applications of the  ST16C550CJ44TR-F**

This part is typically used in:

- PBX and private branch exchange systems
- Customer premises equipment (CPE)
- Modem interfaces (dial-up, ISDN, DSL terminal adapters)
- Embedded computing platforms with serial CPU interfaces
- Industrial control and automation systems
- Data acquisition equipment
- Multi-port serial interface cards
- Network access servers and routers
- Telecom infrastructure equipment
- Serial-to-parallel data conversion in digital systems
- Embedded medical devices requiring serial communication
- Legacy system maintenance and hardware repair
