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 high-efficiency,
charge-pump power supply that requires only 0.F 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 V
L 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 V
L for VOH and transmitter input logic levels
are scaled by the magnitude of the V
L input.
