V0.1 5/9/12’ Prolific Technology Inc. 7F, #48, Sec.3, Nan-Kang Rd., Taipei, Taiwan 115, ROC Tel: 886-2-2654-6363 Fax: 886-2-2654-6161 E-mail : sales@prolific.com.tw http://www.prolific.com.tw OVERVIEW The PL2303TA is a low cost and high performance USB-to-Serial Bridge Controller. The PL2303TA provides a convenient solution for connecting an RS-232 like full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL2303TA 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 PL2303TA 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 PL2303TA is perfect for bus powered operation with plenty of power left for the attached devices. PL2303TA is Pin-to-Pin compatible with PL-2303HXA and PL-2303XA.
