XR16M2551  
HIGH PERFORMANCE LOW VOLTAGE DUART WITH 16-BYTE FIFO AND POWERSAVE FEATURE  
MAY 2007  
REV. 1.0.2  
FEATURES  
GENERAL DESCRIPTION  
1.62 to 3.63 Volt Operation  
1
The XR16M2551 (M2551) is a high performance  
dual universal asynchronous receiver and transmitter  
(UART) with 16 byte TX and RX FIFOs. The device  
operates from 1.62 to 3.63 volts and is pin-to-pin  
compatible to the XR16L2551 and XR16V2551. The  
M2551 includes 2 additional capabilities over the  
XR16M2550: Intel and Motorola data bus selection  
and a “PowerSave” mode to minimize the sleep  
current. It supports Exar’s enhanced features of  
selectable FIFO trigger level, automatic hardware  
(RTS/CTS) and software flow control, and a complete  
modem interface. An internal loopback capability  
Pin-to-pin compatible to Exar’s XR16V2551 and the  
XR16L2551  
Two independent UART channels  
Register set is 16550 compatible  
Data rate of up to 16 Mbps at 3.3 V  
Data rate of up to 12.5 Mbps at 2.5 V  
Data rate of up to 8 Mbps at 1.8V  
Fractional Baud Rate Generator  
Transmit and Receive FIFOs of 16 bytes  
Selectable TX and RX FIFO Trigger Levels  
Automatic Hardware (RTS/CTS) Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Wireless Infrared (IrDA 1.0) Encoder/Decoder  
Automatic sleep mode with wake-up interrupt  
Full modem interface  
allows  
system  
diagnostics.  
Independent  
programmable fractional baud rate generators are  
provided in each channel to select data rates up to 16  
Mbps at 3.3 Volt and 4X sampling clock. The M2551  
is available in 48-pin TQFP and 32-pin QFN  
packages.  
NOTE: 1 Covered by U.S. Patent #5,649,122
