SP3203E Overview
The SP3203E provides a RS-232 transceiver solution for portable and hand-held applications such as palmtops, PDA's and cell phones. The SP3203E uses an internal highefficiency, charge-pump that requires only 0.1µF capacitors during 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3203E to deliver pliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
