PL-2303HX-Edition (Rev D)
USB to Serial Bridge Controller
OVERVIEW
The PL-2303HX is a low cost and high performance USB-to-Serial Bridge Controller. The PL-2303HX
provides a convenient solution for connecting an RS-232 full-duplex asynchronous serial device to any
Universal Serial Bus (USB) capable host. The PL-2303HX highly compatible drivers could simulate the
traditional COM port on most operating systems allowing the existing applications based on COM port to
easily migrate and be made USB ready. The PL-2303HX 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 PL-2303HX is perfect for bus
power operation with plenty of power left for the attached devices. Flexible signal level requirement on the
RS-232 serial port side also allows the PL-2303HX to connect directly to 3.3V ~ 1.8V devices. PL-2303HX
integrates on-chip clock generator and OTP ROM to save external crystal and EEPROM. Customers can
design with effective BOM cost and compact PCB size.
