XR16L788CQ General Description
The XR16L7881 (788), is a 2.97V to 5.5V with 5V tolerant inputs octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for high bandwidth requirement in communication systems. The global interrupt source register provides a complete interrupt status indication for all 8 channels to speed up interrupt parsing. Each UART has its own 16C550 compatible set of configuration registers, TX and RX FIFOs of 64 bytes, fully programmable transmit and receive FIFO trigger levels, TX and RX FIFO level counters, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, autoamtic software (Xon/Xoff) flow control, RS-485 half-duplex direction control with programmable turn-around delay, Intel or Motorola bus interface and sleep mode with a wake-up indicator.
NOTE: Covered by US patents #5,649,122 and #5,949,787
