TL16C554PN Description

Short technical summary and product information.

The Texas Instruments TL16C554PN is a Quad Universal Asynchronous Receiver Transmitter (UART) integrated circuit designed for efficient serial communication. It incorporates four improved TL16C550 ACEs with steering logic, and in FIFO mode, each transmitter and receiver is buffered with 16-byte FIFOs to minimize CPU interrupt frequency.

 

This device operates with a voltage range of 4.75V to 5.25V and supports a maximum data rate of 1Mbps. It includes programmable baud rate generators, allows for standard asynchronous communication bit manipulation (start, stop, parity), and offers independently controlled transmit, receive, line status, and data set interrupts. The TL16C554PN also features false start bit detection, complete status reporting, line break generation and detection, and internal diagnostic capabilities including loopback controls.

 

Packaged in an 80-LQFP (12x12mm) surface-mount configuration, the TL16C554PN is suitable for various embedded systems requiring robust serial communication interfaces. Its design facilitates precise synchronization between the CPU and serial data, making it a reliable choice for applications needing multiple UART channels.
