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.
