EI16C552 - IMP

EI16C552 Dual FIFO UART and Parallel Port

The Ei16C552 is an enhanced dual channel version of the Ei16C550 Universal Asynchronous Receiver Transmitter (UART). The device serves two serial input/output interfaces simultaneously in microcomputer or microprocessor based systems. Each channel performs a serial-to-parallel conversion on data characters received from peripheral devices or modems, and a pa.
