Fonctionnalités et applications

EXAR, the market leader, offers the industry's broadest line-up of UART and serial protocol transceivers solutions.

With over 200 devices, wide 2.25 to 5.5V power supply range, 1 to 128 bytes of FIFO and compliance with the universal 3.3/5V PCI, Intel and Motorola bus interfaces, including single protocol ICs that support RS-232, RS-422 or RS-485 as well as dual and multi-protocol ICs that support from 2 to 8 of the most popular interface standards with a single IC, Exar has already done the difficult work for you.

We can deliver an immediate competitive advantage to your compressed time-to-market demands accelerating initial design, to functioning prototype and finally volume production.

The SP3238E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers.

The SP3238E uses an internal high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump and Exar's driver architecture allow the SP3238E device to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.0V.

The SP3238E includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.

The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1μA.

Features

  • 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
  • AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown
  • Minimum 250Kbps data rate under load
  • Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations
  • Enhanced ESD Specifications:
    • ±15KV Human Body Model
    • ±15KV IEC1000-4-2 Air Discharge
    • ±8KV IEC1000-4-2 Contact Discharge
