Description

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.
