The TL16C554PN is a high-performance quad universal asynchronous receiver-transmitter (UART) integrated circuit from the renowned semiconductor manufacturer, Texas Instruments. This versatile chip is designed to meet the demanding requirements of modern communication systems, providing four independent UART channels in a single package. It is an ideal solution for applications requiring multiple serial interfaces, such as industrial control systems, networking equipment, and multi-port serial cards.

Key Features

• Four Independent UART Channels: Each channel is capable of handling serial communications independently, with a full set of modem control signals to ensure compatibility with a wide range of devices.
• Programmable Baud Rate Generators: Allows precise adjustment of the baud rate for each channel to match specific communication requirements.
• 64-Byte FIFO Buffers: Large FIFOs for each UART channel reduce CPU overhead by minimizing the number of required read and write cycles, especially beneficial in multi-tasking environments.
• Automatic In-Band Flow Control: The device supports in-band flow control using Xon/Xoff characters, facilitating smooth data transfer without the need for additional hardware.
• Modem Control Functions: Each UART includes a full set of modem control signals, ensuring compatibility with modems and other similar peripherals.
• Flexible Character Lengths: Supports 5, 6, 7, or 8-bit character lengths, allowing for customization based on the communication protocol used.
• Even, Odd, or No Parity Bit Generation and Detection: Provides versatile options for data integrity checks.
• Industrial Temperature Range: Designed to operate reliably in harsh environments, with an operational temperature range suitable for industrial applications.
