DESCRIPTION  
The SP3223 products are RS-232 transceiver solutions intended for portable applications  
such as notebook and hand held computers. These products use an internal high-efficiency,  
charge-pump power supply thatrequires only0.ꢀµFcapacitorsin3.3Voperation.Thischarge  
pump and Exar's driver architecture allow the SP3223 series to deliver compliant RS-232  
performance from a single power supply ranging from +3.3V to +5.0V. The SP3223 is a 2-  
driver/2-receiver device ideal for laptop/notebook computer and PDA applications.  
The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shut-  
down state when an RS-232 cable is connected and a connected peripheral is turned on.  
Otherwise, the device automatically shuts itself down drawing less than ꢀµA.
