XR16L788  
HIGH PERFORMANCE OCTAL UART  
SEPTEMBER 2001  
REV. 1.1.4  
NEW FEATURES:  
GENERAL DESCRIPTION  
• 5V and 3.3V 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), formerly XR16L758, is a 5V  
and 3.3V with 5V tolerant inputs octal Universal Asyn-  
chronous Receiver and Transmitter (UART). The  
highly integrated device is designed for high band-  
width requirement in communication systems. A new  
feature increases device driver efficiency includes a  
global interrupt pin with global interrupt source regis-  
ters that provide complete and detailed interrupt sta-  
tus information for all 8 channels that will speed up in-  
terrupt parsing. Other new facilities include simulta-  
neous UART registers initialization, individual UART  
channel soft-reset, DTR/DSR hardware flow control,  
software flow control (Xoff/Xon) detection indicators,  
RS-485 half-duplex direction control with programma-  
ble turn-around delay, Intel or Motorola bus interface  
and sleep mode now has 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  
Automatic Xon/Xoff Software Flow Control with Sta-  
tus Indicator
