DescriptionIC UART PCI BUS QUAD 144LQFP
DescriptionExar XR17D154CV Universal (3.3V and 5V) PCI Bus Quad UART
OverviewThe XR17D1541 (D154) is a quad PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with same package and pin-out as the Exar XR17C158, XR17D158 and XR17C154. The device is designed to meet today’s 32-bit PCI Bus and 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 is independently controlled and has its own 16C550 compatible 5G register set, transmit and receive FIFOs of 64 bytes, fully programmable transmit and receive FIFO trigger levels, transmit and receive FIFO level counters, automatic hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, IrDA (Infrared Data Association) encoder/decoder, 8 multi-purpose inputs/outputs and a 16-bit general purpose timer/counter.
Key FeaturesHigh Performance Quad PCI UART Universal PCI Bus Buffers - Auto-sense 3.3V or 5V Operation 32-bit PCI Bus 2.3 Target Signalling Compliance A Global Interrupt Source Register for all 4 UARTs Data Transfer in Byte, Word and Double-word Data Read/Write Burst Operation Each UART is independently controlled with:- • 16C550 Compatible 5G Register Set- • 64-byte Transmit and Receive FIFOs- • Transmit and Receive FIFO Level Counters- • Automatic RTS/CTS or DTR/DSR Flow Control- • Automatic Xon/Xoff Software Flow Control- • Automatic RS485 Half-duplex Control Output with Selectable Turn-around Delay- • Infrared (IrDA 1.0) Data Encoder/Decoder- • Programmable Data Rate with Prescaler- • Up to 6.25 Mbps Serial Data Rate at 8X Eight Multi-Purpose Inputs/outputs General Purpose 16-bit Timer/Counter Sleep Mode with Automatic Wake-up EEPROM Interface for PCI Configuration Same package and pin-out as the XR17D158, XR17C158 and XR17C154 (20x20x1.4mm 144-TQFP)
