DESCRIPTION

The SP3203E provides a RS-232 transceiver solution for portable and hand-held applications such as palmtops, PDAs and cell phones. The SP3203E uses an internal high-effciency, charge-pump power supply that requires only 0.µF capacitors during 3.3V operation. This charge pump and Exars driver architecture allow the SP3203E to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
