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 that requires only 0.F capacitors in 3.3V operation. This charge
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 A.
