USB to Serial / Parallel

PL2303EA – USB to Serial Bridge Controller

General

  • High Level and System Level ESD Protection.
  • Eliminates the need for one additional chip that
    results in reduced costs.
  • Ideal for mobile devices.

Feature Rich – ESD Safe:

  • System-level ESD Specification on USB Port (4-Pin)
  • ± 15kV IEC 61000-4-2 Air Discharge
  • ± 8kV IEC 61000-4-2 Contact Discharge
  • Fully Compliant with USB Specification v2.0 (Full-Speed)
  • On Chip USB 1.1 transceiver, 5V->3.3V regulator
  • On-chip 96MHz clock generator
  • ± 15kV High ESD HBM (Human Body Model) Protection on USB Port (4-Pin)
  • Pin-to-Pin compatible with PL-2303HXD (HX Rev D) chip and driver compatible
  • Provides drivers support for Windows, Mac OS, Linux, and WinCE compatible
  • The PL2303EA is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily fit in to any connectors and handheld devices. With very small power consumption in either operating or suspend mode, the PL2303EA is perfect for bus powered operation with plenty of power left for the attached devices. Flexible signal level requirement on the RS232-like serial port side also allows the PL2303EA to connect directly to any 3.3V~1.8V range devices.
