XR16L784CV-F

产品概述

The XR16L784CV-F is a quad Universal Asynchronous Receiver and Transmitter (UART) designed for high bandwidth requirement in communication systems. The global interrupt source register provides a complete interrupt status indication for all 4 channels to speed up interrupt parsing. Each UART has its own 16C550 compatible set of configuration registers, transmit and receive FIFOs of 64 bytes, fully programmable transmit and receive FIFO level triggers, transmit and receive FIFO level counters, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, IrDA (Infrared Data Association) encoder/decoder and a 16-bit general purpose timer/counter.

• 8-bit Intel or Motorola data bus interface
• Global interrupt source registers for all channels
• 5G (fifth generation) "Flat" register set
• 16C550 Compatible registers
• 64-byte Transmit and receive FIFOs
• Transmit and receive FIFO level counters
• Programmable TX and RX FIFO trigger level
• Automatic RTS/CTS or DTR/DSR flow control
• Selectable RTS Flow control hysteresis
• Automatic XON/XOFF Software flow control

• Automatic RS485 half-duplex control output with 16 selectable turn-around delay
• Infrared (IrDA 1.1) data encoder/decoder
• Programmable data rate with prescaler
• A general purpose 16-bit timer/counter
• Sleep mode with automatic wake-up indicator
