The ST16C2550CP is a dual universal asynchronous receiver/transmitter (UART) with enhanced features, manufactured by Exar Corporation. This device provides two independent channels of serial communication, each with its own set of control and status registers. It is designed to simplify the interface between a host processor and serial peripherals in a variety of applications.

Applications:

• Multi-port serial cards
• Industrial automation
• Embedded systems
• POS (Point-of-Sale) terminals
• Telecommunications equipment

Features:

• Dual UART channels
• Data rates up to 3 Mbps
• 32-byte transmit and receive FIFOs per channel
• Programmable baud rate generator
• Automatic hardware/software flow control
• Modem control signals
• Interrupt generation
• Multiplexed interrupt output
• 5V Operation
• 48-Pin DIP Package

Benefits:

• Increased throughput: High data rates and large FIFOs improve overall system performance.
• Reduced processor overhead: Automatic flow control and interrupt generation minimize the need for processor intervention.
• Simplified system design: The dual UARTs and enhanced features reduce the need for external components.
• Flexible configuration: Programmable baud rate generator allows for a wide range of communication speeds.
• Reliable communication: Automatic flow control prevents data loss.

The ST16C2550CP's large 32-byte transmit and receive FIFOs help prevent data loss and improve system performance, especially in high-traffic environments. The automatic hardware and software flow control features ensure reliable data transmission by preventing buffer overruns and underruns. The modem control signals enable the control of external modem devices. It uses a programmable baud rate generator, supporting a wide variety of communication speeds. The ST16C2550CP dual UART and enhanced features make it a cost-effective solution for many applications requiring serial communication. The large FIFOs are especially beneficial in applications where the processor may not be able to service interrupts immediately. This versatile UART provides reliable operation. The device is supplied in a 48-Pin DIP package.
