Supplier for ST16C554DIJ68-F in USA: Features, Applications, and Sourcing Guide
When looking for a supplier for ST16C554DIJ68-F in the USA, engineers and purchasing teams need a reliable source for communication interface components used in industrial, embedded, and legacy serial communication systems. The ST16C554DIJ68-F is a high-performance quad universal asynchronous receiver/transmitter (UART) device designed to provide multiple independent serial communication channels in a single integrated circuit. With its multi-channel architecture, programmable communication features, FIFO buffers, and processor interface, the device is well suited for systems that need to manage several asynchronous serial ports without using a separate UART for every channel.
What Is the ST16C554DIJ68-F?
The ST16C554DIJ68-F belongs to the ST16C554 family of quad UART devices associated with Exar's serial communication product portfolio. The ST16C554 architecture provides four independent UART channels, allowing a host processor to communicate with multiple external serial devices through one integrated component.
The device is designed for asynchronous serial communication and is compatible with common RS-232, RS-422, and RS-485 system architectures when used with the appropriate external transceivers. Importantly, the UART itself handles the digital serial data conversion and protocol-related functions, while external interface drivers and receivers provide the required physical-layer voltage levels.
The ST16C554DIJ68-F includes transmit and receive FIFOs intended to reduce processor intervention during serial data transfers. This is especially useful in systems where multiple communication channels are active simultaneously. Instead of requiring the CPU to service every individual received character immediately, FIFO buffering allows data to accumulate temporarily while the processor performs other tasks.
The “DIJ68-F” designation identifies a particular package and ordering configuration. When sourcing this device, engineers should always verify the complete manufacturer part number, package type, temperature rating, revision, and electrical specifications rather than selecting a component solely by the ST16C554 family name.
Key Features of ST16C554DIJ68-F
One of the main advantages of the ST16C554 is its four-channel UART architecture. A single chip can replace several individual UART devices, helping reduce PCB component count and simplifying system design.
Each UART channel provides independent serial communication functionality. Depending on the system configuration, the channels can be connected to terminals, modems, sensors, controllers, barcode readers, industrial instruments, or other serial peripherals.
FIFO buffering is another important feature. The ST16C554 family is designed with transmit and receive FIFOs that help improve system efficiency, particularly when serial communication traffic is continuous or occurs on several ports at the same time. Buffering can reduce the frequency of CPU interrupts and provide additional time for the processor to handle other system operations.
The device also supports programmable baud rates and common asynchronous serial communication formats. This makes it adaptable to equipment operating at different communication speeds and configurations.
From a system architecture perspective, the ST16C554 is particularly attractive when a processor needs several serial ports but does not have enough integrated UART peripherals. Instead of changing to a more expensive processor with additional serial interfaces, designers can add a multi-channel UART externally.
ST16C554 Related Models
When searching for an ST16C554DIJ68-F supplier, buyers may also encounter related members of the ST16C554 and ST16C550-family UART product lines.
The ST16C554 is a quad-UART architecture, while related ST16C552 devices provide fewer serial channels. Other ST16C550-family products may offer single- or dual-channel configurations. These alternatives can be useful when designing different levels of serial connectivity.
The ST16C454 is another related quad-UART device in the broader ST16C45x family. Depending on the application, engineers may also encounter enhanced UART versions with different FIFO capacities, bus interfaces, power characteristics, or packaging.
However, similar model numbers do not necessarily mean direct interchangeability. Designers should compare register architecture, interrupt behavior, FIFO implementation, clock requirements, package pinout, supply voltage, and electrical characteristics before selecting a replacement.
Applications of ST16C554DIJ68-F
Industrial Automation
Industrial automation is one of the strongest application areas for multi-channel UART devices. Factory equipment frequently needs to communicate with several external devices at the same time. A controller may need one serial port for a human-machine interface, another for a motor controller, another for a measurement instrument, and another for a PLC or supervisory system.
Using a four-channel UART allows these communication functions to be consolidated into a single device. The processor can manage several independent serial streams while the UART handles the low-level transmission and reception of asynchronous data.
This architecture can be particularly useful when upgrading older industrial controllers. Many industrial machines continue to use serial communication because RS-232 and RS-485 interfaces are robust, inexpensive, and supported by a large installed base of equipment.
Industrial PCs and Embedded Computers
Industrial PCs often require more serial interfaces than a standard desktop computer. Applications such as machine vision, factory monitoring, automated testing, and equipment management may need multiple serial connections.
The ST16C554 can provide additional UART channels to an embedded processor, microprocessor, or computer bus. External transceivers can then convert the UART signals to the appropriate physical interface.
For example, one channel can communicate with a temperature controller while the remaining channels communicate with weighing equipment, a programmable instrument, and a barcode scanner. This makes the quad-UART architecture especially useful in equipment that acts as a central communication gateway.
Point-of-Sale and Retail Equipment
Retail and point-of-sale systems have historically used multiple serial peripherals. Receipt printers, barcode scanners, customer displays, payment-related equipment, cash drawers, and other accessories may communicate through serial interfaces.
A multi-port UART can simplify the internal communication architecture of such equipment. Rather than dedicating separate communication ICs to every serial peripheral, the system can consolidate several channels into one component.
For legacy POS equipment, replacement availability is also important. A machine may remain operational for many years, and maintaining the original communication architecture can be easier than redesigning the entire motherboard.
Automated Test Equipment
Automated test systems often need to control several instruments simultaneously. Digital multimeters, power supplies, signal generators, programmable loads, environmental chambers, and other laboratory devices may use asynchronous serial interfaces.
The ST16C554 can provide multiple independent UART channels for these instruments. A host controller can send commands through one channel while receiving measurement data from another. FIFO buffering can also help manage bursts of incoming information without requiring constant processor attention.
This makes multi-channel UART technology valuable in test systems where reliable communication with several instruments is more important than extremely high-speed networking.
Telecommunications and Networking Equipment
Although modern networking equipment increasingly relies on Ethernet and high-speed serial interfaces, asynchronous UARTs remain important for management ports, configuration consoles, diagnostics, and communication with auxiliary controllers.
A four-channel UART can support several maintenance or management interfaces inside telecommunications equipment. It can also be used to communicate with modems, embedded controllers, power-management systems, and other subsystems.
During development and maintenance, serial console interfaces are especially valuable because they provide engineers with direct access to system status and diagnostic information.
Security and Access-Control Systems
Security equipment frequently contains several peripheral devices. Access-control panels may communicate with card readers, keypads, biometric devices, alarm modules, printers, and other controllers.
A quad UART provides an efficient way to manage these serial peripherals. Different channels can operate independently, allowing the central processor to receive information from several devices without needing multiple standalone UART chips.
This approach is also useful in building automation and security gateways where multiple low-speed serial devices need to be integrated into a single embedded controller.
Transportation and Fleet Equipment
Vehicle and transportation systems can contain numerous electronic modules that communicate through serial interfaces. Fleet terminals, diagnostic equipment, GPS-related peripherals, displays, ticketing systems, and specialized controllers may require asynchronous serial communication.
For maintenance equipment and legacy transportation controllers, a multi-channel UART can provide the connectivity required to communicate with several external devices. The availability of independent channels makes it possible to create a compact communication gateway without dramatically increasing PCB complexity.
Data Acquisition and Measurement Systems
Measurement equipment frequently collects information from multiple sensors or instruments. Although many modern sensors use SPI, I²C, USB, or Ethernet, serial interfaces remain common in industrial instruments and older measurement devices.
The ST16C554 can serve as the communication hub between an embedded processor and multiple serial instruments. FIFO buffering is particularly helpful when several devices transmit data at unpredictable intervals.
In long-life measurement systems, maintaining compatibility with existing serial instruments can be more practical than replacing every connected device with a modern interface.
