3.0 Introduction
PL-2303HX (Chip Rev D) or PL-2303HXD provides a convenient solution for connecting an RS232-like
full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. PL-2303HXD
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.
By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control,
PL-2303HXD is capable of achieving higher throughput compared to traditional UART (Universal
Asynchronous Receiver Transmitter) ports. When real RS232 signaling is not required, baud rate
higher than 115200 bps could be used for even higher performance. The flexible baud rate generator of
PL-2303HXD could be programmed to generate any rate between 75 bps to 12M bps.
PL-2303HXD 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, PL-2303HXD is perfect for bus powered operation
with plenty of power left for the attached devices. Flexible signal level requirement on the RS232-like
serial port side also allows PL-2303HXD to connect directly to any 3.3V~1.8V range devices.

Warning: The exposed center die pad of the PL-2303HX QFN package is connected (bonded) to the
pin VO_33 so it is very important to design the PCB layout wherein this exposed die pad
won’t get grounded on the PCB when mounted.

6.0 OTPROM Configuration
The default configuration descriptors are stored in the chip internally which will be loaded during
power-on reset or USB bus reset whenever OTPROM (One-Time Programmable ROM) is empty.
Several of the USB descriptors could be modified and stored to the PL2303HXD OTPROM during
device startup like Vendor ID (VID), Product ID (PID), Serial Number, Product String, and other
configuration descriptors. The OTPROM can be programmed twice using the Prolific PL2303 EEPROM
Writer utility software which can be requested from Prolific or authorized distributors.

Description
Serial Port Output
Disable
This option allows setting the serial port output
pin signals (TXD, RTS, DTR) to HIGH during
suspend mode.
USB Load Mode
Light Load (100mA)
This option sets the USB device maximum
power if 100mA (low-power) or 500mA (high
power).
This option allows to set the flow control initial
setting to none, H/W, or S/W control.
Flow Control Setting
No Flow Control
Wakeup Trigger Pin
Wakeup trigger on
RI
This option allows setting the trigger pin for
remote wakeup function. When in suspend
mode, changes on the enabled serial port
input signals could trigger a wakeup event.
Shutdown Pin Mode
Output LOW during
suspend
This option allows setting the Shutdown pin
mode to Output HIGH or LOW on normal
mode or Suspend mode.

8.0 PL2303HXD Reference Schematic Diagram
Below is an example of using the PL-2303HX (Chip Rev D) as a USB to RS232 converter (with RS485
option) where a RS232 transceiver (Sipex SP213EHCA) is used to convert the TTL levels serial
interface of the PL2303TA to RS232 levels as well as converting the +5V nominal VCC to the ±9V
required by RS232. The SP213EHCA transceiver provides up to 500Kbps data rate transmission which
is ideal for many designs requiring high speed performance. Contact Prolific FAE for more PCB design
support.
