DESCRIPTION
The SP3203E provides a RS-232 transceiver solution for portable and hand-held applications
such as palmtops, PDA's and cell phones. The SP3203Euses an internal high-efficiency,
charge-pump power supply that requires only 0.µF capacitors during 3.3V operation. This
charge pump and Exar's driver architecture allow the SP3203E
to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
The SP3203E is a 3-driver/2-receiver device, with a unique VL pin to program the TTL input and output logic levels to allow inter operation in mixed-logic voltage systems such as PDA's and cell phones. Receiver outputs will not exceed VL or VOH and transmitter input logic levels are scaled by the magnitude of the VL input.
