TL16C554AFNR Description

Short technical summary and product information.

The Texas Instruments TL16C554AFNR is a Quad UART (Universal Asynchronous Receiver Transmitter) integrated circuit designed for serial communication. It consists of four improved TL16C550C ACEs with steering logic. In FIFO mode, each ACE transmitter and receiver is buffered with 16-byte FIFOs, significantly reducing the number of interrupts to the CPU.

 

This device supports a maximum data rate of 1Mbps and operates over a wide voltage range of 3V to 5.25V. It includes programmable baud-rate generators, allows for standard asynchronous communication bit manipulation (start, stop, parity), and offers independently controlled interrupts for transmit, receive, line status, and data set. The TL16C554AFNR also features auto flow control and modem control functions.

 

Packaged in a 68-PLCC (J-Lead) format, the TL16C554AFNR is designed for surface mounting. Its operating temperature range is -40°C to 85°C. The integrated diagnostic capabilities, including loopback controls and error simulation, aid in communications link fault isolation. This component is suitable for various embedded systems requiring reliable serial data transmission.
