XR16L788  
HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART  
JULY 2008  
REV. 1.2.3  
FEATURES  
GENERAL DESCRIPTION  
• 2.97V to 5.5V with 5V Tolerant Inputs Operation  
• Single Interrupt Output for all 8 UARTs  
• Global Interrupt Source for all 8 UARTs  
• 5G “Flat” UART Registers for Configurations  
• Simultaneous UART Channels Initialization  
The XR16L7881 (788), is a 2.97V to 5.5V with 5V  
tolerant inputs octal Universal Asynchronous  
Receiver and Transmitter (UART). 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, 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.  
• Auto RS485 Half-duplex Control with Program-  
mable Turn-around Delay  
• A General Purpose 16-bit Timer/Counter  
• Sleep Mode with Wake-up Indication  
• Highly Integrated Device for Space Saving  
• First eight registers are 16C550 compatible  
• 64-byte Transmit and Receive FIFOs  
• Transmit and Receive FIFO Level Counters  
• Programmable TX and RX FIFO Trigger Levels  
• Automatic RTS/CTS or DTR/DSR Flow Control  
• Selectable Hardware Flow Control Hysteresis  
NOTE: Covered by US patents #5,649,122 and #5,949,787  
APPLICATIONS  
• Remote Access Servers  
• Ethernet Network to Serial Ports  
• Network Management  
• Factory Automation and Process Control  
• Point-of-Sale Systems  
• Multi-port RS-232/RS-422/RS-485 Cards  
• Automatic Xon/Xoff Software Flow Control with  
Status Indicator  
• Infrared (IrDA 1.0) Data Encoder/Decoder  
• Programmable Data Rate with Prescaler  
• Up to 6.25 Mbps Serial Data Rate at 5V  
• 100-pin QFP Package (14x20x3 mm)
