TL16CP554AIPM

The TL16CP554AIPM is a Quad UART (Universal Asynchronous Receiver Transmitter) integrated circuit manufactured by Texas Instruments. It is built upon four improved TL16C550C ACEs with steering logic, and in FIFO mode, each ACE transmitter and receiver is buffered with 16-byte FIFOs to minimize CPU interrupts. This device supports a maximum clock rate of 16 MHz, enabling operation up to 1-Mbaud with supply voltages of 3.3V and 5V.

Key features include programmable baud-rate generators, standard asynchronous communication bit manipulation (start, stop, parity), independently controlled interrupts, and 5V/3.3V operation. It offers fully programmable serial interface characteristics, including 5-, 6-, 7-, or 8-bit characters, even/odd/no parity, and 1-, 1.5-, or 2-stop bit generation. The TL16CP554AIPM also includes false start bit detection, complete status reporting, line break generation/detection, and internal diagnostic capabilities like loopback controls for fault isolation.

This UART supports modem control functions (CTS, RTS, DSR, DTR, RI, DCD) and features programmable auto-RTS and auto-CTS. The device is available in a 64-LQFP package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.
