Each UART transmits data sent to it from the peripheral 8-bit bus on the TX signal and receives characters on

the RX signal. Characters can be programmed to be 5, 6, 7, or 8 bits. The UART has a 64-byte receive FIFO and

transmit FIFO and can be programmed to interrupt at different trigger levels. The UART generates its own

desired baud rate based upon a programmable divisor and its input clock. It can transmit even, odd, or no parity

and 1-, 1.5-, or 2-stop bits. The receiver can detect break, idle or framing errors, FIFO overflow, and parity errors.

The transmitter can detect FIFO underflow. The UART also contains a software interface for modem control

operations, and software flow control and hardware flow control capabilities.

The '754C is available in 80-pin TQFP PN and 64-pin TQFP PM packages.

There are two versions available in the PM package, the TL16CP754C and the TL16CM754C. The ’CP754C
