TL16C2550IPFB Description

The TL16C2550IPFB from Texas Instruments is a high-performance dual UART (DUART) designed for embedded systems requiring reliable serial communication. Housed in a 48-TQFP package, this surface-mount IC integrates two independent UART channels, each equipped with a 16-byte FIFO to minimize CPU overhead and enhance data throughput. Operating across a 1.8V to 5V supply range, it supports data rates up to 1.5Mbps, making it suitable for both low-power and high-speed applications. Key features include auto flow control, modem control signals, and false start bit detection, ensuring robust error handling and compatibility with legacy systems. Its internal oscillator simplifies design by reducing external components.

TL16C2550IPFB Features

• Dual UART Channels: Two independent channels for simultaneous serial communication.
• 16-Byte FIFOs: Reduces CPU interrupts and improves efficiency in high-traffic environments.
• Auto Flow Control: Hardware-based (RTS/CTS) flow control prevents data overrun.
• Modem Control: Supports modem interface signals (DTR, DSR, etc.) for telecommunication applications.
• Wide Voltage Range: Operates from 1.8V to 5V, ideal for mixed-voltage systems.
• False Start Bit Detection: Enhances noise immunity in electrically noisy environments.
• Internal Oscillator: Eliminates the need for an external clock source, reducing BOM cost.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
