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 high-efficiency, charge-pump power supply that requires only 0.1µF capacitors during 3.3V operation. This charge pump and Exar's driver architecture allow the SP3203E to deliver pliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
SP3203E Key Features
- 3 Driver / 2 Receiver Architecture
- Logic selector function (VL) sets TTL
- Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
- Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source
- Minimum 250Kbps data rate under load
- Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations
