IMP16C554 Quad Universal Asynchronous Receiver/Transmitter (UART) with FIFOs

The IMP16C554 is a universal asynchronous receiver and transmitter with 16 byte transmit and receive FIFO. A programmable baud rate generator is provided to select transmit and receive clock rates from 50Hz to 1.5MHz. The IMP16C554 is an improved version of the IMP16C550 UART with higher operating speed and lower access time. The IMP16C554 on board status r.
