XR16M681  
1.62V TO 3.63V UART WITH 32-BYTE FIFO AND VLIO INTERFACE  
AUGUST 2009  
REV. 1.0.1  
FEATURES  
GENERAL DESCRIPTION  
VLIO bus interface  
1
The XR16M681 (M681) is an enhanced Universal  
Asynchronous Receiver and Transmitter (UART) with  
a VLIO bus interface and has 32 bytes of transmit  
and receive FIFOs, programmable transmit and  
receive FIFO trigger levels, automatic hardware and  
software flow control, and data rates of up to 20 Mbps  
at 3.3V, 16 Mbps at 2.5V and 10 Mbps at 1.8V with  
4X data sampling rate.  
Pin-to-pin compatible with SC16C850V and  
SC16C850SV in 32-QFN package  
20 Mbps maximum data rate  
Programmable TX/RX FIFO Trigger Levels  
TX/RX FIFO Level Counters  
Independent TX/RX Baud Rate Generator  
Fractional Baud Rate Generator  
Auto RTS/CTS Hardware Flow Control  
Auto XON/XOFF Software Flow Control  
Auto RS-485 Half-Duplex Direction Control  
Multidrop mode w/ Auto Address Detect  
Sleep Mode with Automatic Wake-up  
PowerSave mode  
The Auto RS-485 Half-Duplex Direction control  
feature simplifies both the hardware and software for  
half-duplex RS-485 applications. In addition, the  
Multidrop mode with Auto Address detection  
increases the performance by simplifying the  
software routines.  
The Independent TX/RX Baud Rate Generator  
feature allows the transmitter and receiver to operate  
at different baud rates. Power consumption of the  
M681 can be minmized by enabling the sleep mode  
and PowerSave mode.  
Infrared (IrDA 1.0 and 1.1) mode  
1.62V to 3.63V supply operation  
Crystal oscillator or external clock input  
APPLICATIONS  
The M681 has a 16550 compatible register set that  
provide users with operating status and control,  
receiver error indications, and modem serial interface  
controls. An internal loopback capability allows  
onboard diagnostics. The M681 is available in 24-pin  
QFN, 32-pin QFN and 25-pin BGA packages.
