XR16L788IQ-F

UART 接口集成电路 2.97V TO 5.5V 64B FIFO temp -45 to 85C HIGH PERFORMANCE OCTAL UART

GENERAL DESCRIPTION

The XR16L788IQ-F 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.
