XR17C158CV-F 5V PCI BUS OCTAL UART
General Description:
The XR17C1581 (158) is an octal Universal Asynchronous Receiver and Transmitter (UART). The device is designed to meet the 32-bit PCI Bus and 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, 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, 8 multi-purpose definable inputs/outputs, and a 16-bit general purpose timer/counter.
Key Features:
- High Performance Octal UART
- 32-bit PCI Bus Interface with EEPROM Interface
- Interrupt Source Register for all 8 UARTs
- Data Transfer in Byte, Word and Double-word
