PI7C9X798ME

Pb A product Line of Diodes Incorporated Lead-free Green PI7C9X798 High Performance 1.62V To 3.6V Octal Uart with 64-Byte FIFO Features Description ÎÎ1.62V to 3.6V with 5V Tolerant Serial Inputs The PI7C9X798 (798), is a 1.62V to 3.6V octal Universal Asynchronous Receiver and Transmitter (UART) with 5V tolerant serial (modem) inputs. 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, automatic software (Xon/ Xoff) flow control, RS-485 half-duplex direction control, and auto address detection, Intel or Motorola bus interface and sleep mode with a wake-up indicator. ÎÎSingle Interrupt output for all 8 UARTs ÎÎA Global Interrupt Source Register for all 8 UARTs ÎÎ5G “Flat” UART Registers for easier programming ÎÎSimultaneous Initialization of all UART channels ÎÎA General Purpose Command-driven 16-bit Timer/counter ÎÎSleep Mode with Wake-up Indication ÎÎHighly Integrated Device for Space Saving ÎÎEach UART is independently controlled with: àà 16C550 Compatible 5G Register Set àà 64-byte Transmit and Receive FIFOs àà Transmit and Receive FIFO Level Counters àà Programmable TX and RX FIFO Trigger Level àà Automatic RTS/CTS or DTR/DSR Flow Control àà Automatic Xon/Xoff Software Flow Control àà RS485 HDX Control Output àà RS485 auto address detection àà Infrared (IrDA 1.0/1.1) Data Encoder/Decoder àà Programmable Data Rate with Prescaler ÎÎUp to 8 Mbps Serial Data Rate with 64MHz external clock input Application ÎÎRemote Access Servers ÎÎEthernet Network to Serial Ports ÎÎNetwork Management ÎÎFactory Automation and Process Control ÎÎPoint-of-Sale Systems ÎÎCrystal oscillator(up to 24MHz) or external clock(up to 80MHz) input ÎÎMulti-port RS-232/RS-422/RS-485 Cards ÎÎBuilt in Power-On-Reset circuit ÎÎTotally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) ÎÎHalogen and Antimony Free. “Green” Device (Note 3) Notes:       1.
