XR16V794  
HIGH PERFORMANCE 2.25V TO 3.6V QUAD UART WITH FRACTIONAL  
JULY 2008  
REV. 1.0.1  
FEATURES  
GENERAL DESCRIPTION  
2.25V to 3.6V with 5V Tolerant Serial Inputs  
Single Interrupt output for all 4 UARTs  
A Global Interrupt Source Register for all 4 UARTs  
5G “Flat” UART Registers for easier programming  
Simultaneous Initialization of all UART channels  
1
The XR16V794 (794), is a 2.25V 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 4 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.  
A General Purpose Command-driven 16-bit  
Timer/counter  
Sleep Mode with Wake-up Indication  
Highly Integrated Device for Space Saving  
Each UART is independently controlled with:  
16C550 Compatible 5G Register Set  
64-byte Transmit and Receive FIFOs  
Fractional Baud Rate Generator  
Transmit and Receive FIFO Level Counters  
Programmable TX and RX FIFO Trigger Level  
Automatic RTS/CTS or DTR/DSR Flow Control  
Automatic Xon/Xoff Software Flow Control  
NOTE: Covered by US patents #5,649,122 and #5,949,787  
APPLICATIONS  
RS485 Half-Duplex Control Output with  
Remote Access Servers  
Selectable Turn-around Delay  
Ethernet Network to Serial Ports  
Network Management  
Factory Automation and Process Control  
Point-of-Sale Systems  
Infrared (IrDA 1.0) Data Encoder/Decoder  
Programmable Data Rate with Prescaler  
Up to 8 Mbps Serial Data Rate  
Pin compatible to XR16L784. Same 64-pin LQFP  
Package (10x10x1.4 mm)  
Multi-port RS-232/RS-422/RS-485 Cards
