The XR16L7881 (788), formerly XR16L758, is a 5V and 3.3V with 5V tolerant inputs octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for high bandwidth requirement in communication systems. A new feature increases device driver efficiency includes a global interrupt pin with global interrupt source registers that provide complete and detailed interrupt status information for all 8 channels that will speed up interrupt parsing. Other new facilities include simultaneous UART registers initialization, individual UART channel soft-reset, DTR/DSR hardware flow control, software flow control (Xoff/Xon) detection indicators, RS-485 half-duplex direction control with programmable turn-around delay, Intel or Motorola bus interface and sleep mode now has a wake-up indicator.
