PL2303TB
USB to Serial and GPIO Bridge Controller
OVERVIEW
The PL2303TB is a low cost and high performance USB-to-Serial/GPIO Bridge Controller. The
PL2303TB provides a convenient solution for connecting an RS-232 like full-duplex asynchronous
serial device and GPIO to any Universal Serial Bus (USB) capable host. The PL2303TB 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 PL2303TB supports up to 12 GPIO pins
including RS232 accessing LED, PWM and multiple clock output functions. With very small power
consumption in either operating or suspend mode, the PL2303TB is perfect for bus powered operation
with plenty of power left for the attached devices.
